AQ3010 Meter

Overview

Thermo Scientiﬁc Orion AQUAfast AQ3010 Turbidity Meter User Guide

Thank you for selecting the waterproof portable AQ3010 turbidity meter.

The AQ3010 meter allows you to measure turbidity of an aqueous sample in the field. This instrument operates on the nephelometric principle of turbidity measurement and is designed to meet the criteria specified in ISO 7027 and DIN 27027 standar Principle section

Functions

The keypad has five keys: ON/OFF, CAL, ▲, ▼ and READ/ENTER.

Key Functions

Powers on and off the meter. The meter automatically shuts off 20 minutes after last key press to conserve the battery life.

Initiates the calibration mode of the meter. When pressed, the meter is set to accept the first calibration standard.

It is also used to exit the calibration mode if the user does not want to follow the complete calibration procedure.

When in measurement mode, the READ/ENTER key is used to perform a measurement.

Single-shot measurements: When the key is pressed and released immediately (a quick key stroke of less than 0.3 seconds), the display will blink [-Rd-] ten times and display the measured value.

Continuous measurements: If the READ/ENTER key is pressed and held, the instrument will perform a continuous measurement during which the display is updated every 2 seconds. This can be used for indexing vials. (This function is not available in calibration mode). After the READ/ENTER key is released, the instrument will automatically perform a single-shot measurement.

Active only during calibration mode. These scroll keys are used to select the next calibration point.

Note: After the successful calibration of one point, the meter automatically selects the next calibration point, or automatically exits the calibration mode after the fourth calibration point.

Four AAA batteries are included in the carrying case.

Note: Use caution when loosening the screws, as some of the screws may be tightly seated

1. Use a Phillips screwdriver to loosen the four screws holding the

battery cover. See Figure 4. attached to the battery cover.

2. Remove the battery cover.

Chapter 2 Turbidity Calibration

Calibration

Overview

Indexing

The AQ3010 turbidity meter was calibrated and tested prior to leaving the factory. The meter kit includes a set of prepared primary standards that can be used to verify the meter calibration daily and to recalibrate the

, if required. Before measuring samples for the first time, verify the

meter meter calibration with the prepared primary standards.

The SDVB primary standards in the meter kit are in plastic bottles for impr

oved precision and shelf life. Four vials are included and labeled for

each standard level.

The instrument includes a light shield cover to keep stray light from changing the calibration and sample measur environments, the light shield is not required. The vial cap keeps stray light from entering the sample well, saving you many steps and reducing analysis time

Due to the high quality of the glass vials provided, indexing is not r

equired. You only need to align the mark on the vial with the mark on the meter. However, in order to achieve a better precision of the measurement, you can proceed with indexing of the vials. See the Indexing a Vial section for mor

We recommend that you use the following materials during calibration to achieve the precision stated in this user guide:

•

CAL 1: 800 NTU calibration standard

• CAL 2: 100 NTU calibration standard

• CAL 3: 20.0 NTU calibration standard

• CAL 4: 0.02 NTU calibration standard

It is well known that diluted Formazin is unstable. If you choose to use Formazin to calibrate the instrument, ensure that you are using a fresh stock suspension of Formazin to achieve the precision quoted for the instr

ument. It is very difficult to accurately pipet Formazin for low level NTU standards, due to the non-homogeneous nature of Formazin and because these standar to use good laboratory technique and accurate Class A pipets and refer to ASTM Method 6855-03 for low level standard vial preparation when using F
