Simple and compact
The METTLER TOLEDO RM40/RM50 refractometers are modern, compact instruments suitable for use in a vast diversity of application areas. They can be used, for example, in quality control as well as in research and development and meet the most demanding requirements.
These compact refractometers perfectly combine simple, easy-to-understand operation with an extremely high level of measuring accuracy and outstanding reliability. With their plug & play capability, they automatically detect external devices and sensors.
These refractometers can be operated as standalone instruments or run from a computer using the LabX PC software. Straightforward user guidance on the large color touchscreen enables intuitive operation. User-defin able shortcuts allow all functions to be activated directly from the home screen with a single click.
Touchscreen control of the instrument and the method function parameters are described in the Operating Instructions. The Installation Instructions explain all the necessary steps for setting up your instrument. You are then guided through the first refractive index measuring process with the aid of a practical example. If you have any additional questions, METTLER TOLEDO is always available to assist you.

7Introduction

2Description of the Refractometer
The RM40 / RM50 refractometers measure the refractive index nD of liquids. The two instruments differ in mea suring precision. Both instruments:
measure liquids whose refractive indices range respectively from 1.3200 to 1.7000 (RM40) and to
1.58000 (RM50).
require only minimal sample quantities for measurements (0.5 mL),
maintain the temperature of the sample constant with the aid of a built-in Peltier thermostat in a range from 5 to 100°C (RM40) and 5 to 75°C (RM40).
directly indicate the sugar content of samples in various sugar units (Brix, invert sugar, HFCS42 or HFCS55)
calculate the concentration of a solution by means of data from measured standard solutions, literature tables or formulas
are equipped with an integrated test function that enables regular testing of the accuracy of the measure ment,
enable checking of the product-related specification limits and generate rolling statistics.
The samples can be introduced manually with a syringe. For the optimal use of the RM refractometers, the fol lowing pumps and sample changers are available:

8 Description of the Refractometer

A maintenance-free LED is used as a light source for the measurements.
The measuring prism is made of sapphire. It is therefore extremely corrosion resistance and very robust. It also has a high thermal conductivity.
For temperature measurement, NTC thermistors with extreme long-term stability are used. This means that there is no need to regularly readjust the measuring cell.

3.1Definition of the Refractive Index
The refractive index of a substance is the ratio of the speed of a light beam in a vacuum to its speed in the sub stance (dimensionless).
If a light beam crosses at a certain angle from an optically less dense to an optically denser medium (e.g. from air to water), it is deflected; when the beam crosses from one medium to another perpendicularly no directional change takes place. According to Snell's law, the ratio of the refractive index of the two media is proportional to the ratio of the incident and refrac tive angle of the light beam:
If a light beam passes from an optically denser to a less dense medium, it is also deflected. If the angle of incidence α is increased, then it reaches a critical value, at which the light beam no longer enters the less dense medium (refractive angle
= 90°). When this "critical angle" is exceeded, total internal reflection occurs. The refractive index is calculated from this critical angle α :
As refraction depends on the wavelength of the incident light, the refractive index n is measured as standard with the D line of sodium (wavelength 589.3 nm) and designated nD.
The refractive index not only depends on the wavelength of the light but also on the temperature of the mea sured sample. For this reason the temperature must always be stated along with the result, e.g. n The standard temperature is 20 °C.

D
The light emitted from the light source passes through the prism and hits the sample. In the process it is partly refracted (angle of incidence < critical angle) and partly reflected (angle of incidence > critical angle).
The reflected light is measured by means of an optical sensor (CCD). The boundary between the dark and light area corre sponds to the critical angle required for calculation of the refractive index.

3.3Design of Measuring Cell
The light source is a light-emitting diode (LED), whose beam passes through a polarization filter, an interfer ence filter (589.3 nm) and various lenses before it reaches the sample via the sapphire prism. The reflected light (angle of incidence > critical angle) is deflected via a lens to the optical sensor that determines the critical angle. The temperature in the prism/sample boundary is measured with a built-in sensor.

A distinction should be made between the following two cases in the installation of instruments:
1.
There is still no setup entry available in the unit (delivery state). A new entry has been generated and the parameters automatically generated.
2.
A setup entry was previously manually created in the instrument: The PnP parameters are automatically entered, the remaining parameters, previously edited by the user, remain unchanged.
18 Setup
When a PnP instrument is unplugged, the status changes to "not installed".
Below is described how you can administer the various devices in setup. This includes the creation of devices or changing the parameters in the setup.
Create automation units
So that methods for the application of automation units can be created and configured without the automation unit being connected, these units must be created in the setup via the button New.
Delete automation unit
It is not possible to delete the entry of a connected device.
If you want to delete an entry for a unit that is not connected from the list, a message with the termination option appears indicating that after deletion the methods that use the external instruments will no longer be exe cutable.

2.
A setup entry was previously manually created in the instrument: The PnP parameters are automatically entered, the remaining parameters, previously edited by the user, remain unchanged.
When a PnP instrument is unplugged, the status changes to "not installed".

Via the button External instruments in the Hardware dialog, you can obtain the list of instruments. By touching a list entry, you obtain more detailed information about the corresponding instrument.

Create device
So that methods can be created and configured with external instruments, without having to connect the instru ment, the setup entries of the external instruments can be manually created via the button New.
The pH and conductivity meters can be assigned names individually using the "Instrument" parameter.
Delete devices
It is not possible to delete the entry of a connected device.
If you want to delete an entry for a unit that is not connected from the list, a message with the termination option appears indicating that after deletion the methods that use the external instruments will no longer be exe cutable.

19Setup
3 For temperature compensation, set the unit [°C] at the measuring instruments. Two types of temperature
compensation exist:
- ATC (automatic temperature compensation) with a temperature sensor connected.
- MTC (manual temperature compensation) with no temperature sensor connected. Note: The pH or conductivity meters switch automatically, depending on the arrangement. If the temperature unit at the pH meter or conductivity meter is set to [°C], the results "TpH" and "TCond" will be converted to the temperature unit set in the instrument, i.e. either [°C] or [°F] . By contrast, if [°F] is set at the pH or conductivity meter, no result will be calculated. "--" will be output in the results field.
The conductivity units are [mS/cm]/ [μS/cm] (depending on the range) or [mS/m][μS/m] (depending on the range). However, the results are expressed in [μS/cm]. If you wish to have the result displayed in [mS/cm] or [mS/m][μS/m], it will be necessary to recalculate the result using the "Calculation" method function.
Colorimeter
- Lovibond
The Lovibond colorimeter can be used for extinction or transmission measurements. The wavelengths are out put in 5nm (in the range 420 – 710nm).
A color measurement may take longer than 25s.
- Minolta colorimeters CM-5 / CR-5
The Minolta colorimeters can be used for transmission measurements (liquids). Transmission data are supplied in 10nm increments within the spectral range 360 – 740nm. A color measurement takes approximately 1s. The measurements involve high-energy light flashes. For this reason, color scales are not offered for reflection measurements in the crude oil industry.
The CR-5 colorimeter does not supply any spectral data.
Calibration is possible directly at the colorimeter only. The USB link must be disconnected.
"Illuminant" and "Observer" can be set in the "Configuration" method function. For more information, see "Methods and products: Method functions> Configuration (page42)".
- Color scales Navigation: Home > Setup > Hardware > External instruments > Parameters

Navigation: Setup>Hardware>Auxiliary Instruments
Auxiliary instruments can be any instruments that access the 24V output or USB-RS232 adapter of the measur ing instrument and that are to be used in a method.
An auxiliary instrument that accesses the 24V output is switched on for a predefined period and then switched off again via the corresponding command. The instruments are controlled via the "Auxiliary instrument" method function.
Auxiliary instruments form part of a method, while peripheral devices are classified as input/output devices (printers, barcode readers etc.), which do not have direct access to methods.
Starting from the auxiliary instrument list, you can add new auxiliary instruments or select existing ones or modify their parameters. In addition, the selected auxiliary instruments can be deleted.
A maximum of 30 auxiliary instruments can be entered.
