Description

Versatile in application

Nowadays, fast and simple testing of thermometers is a “must” when it comes to the operational safety of machines and plants. The portable calibrators of the CTx9100 family are particularly suited for on-site calibrations and extremely user-friendly. Due to their compact design and their low weight, the instruments can be taken and used almost anywhere.

Using a dry-well calibrator or a micro calibration bath to calibrate either surface thermometers or non-contact

thermometers does not reect the application and can result

in false values. In these cases, the model CTM9100-150 temperature multi-function calibrator should be used.

With this temperature multi-function calibrator, in the temperature range from -20 ... +150 °C [-4 ... +302 °F], you can cover not only the common functions, but also, with special inserts, this can be used as a surface temperature calibrator and an infrared black body. Like having four instruments in one!

Easy to use

The temperature multi-function calibrator combines four application possibilities in one instrument. The simple instrument design enables fast and simple switching, back and forth, between individual applications. Changing between the four possibilities can be made very easily using one of the four keys and the toggle switch on the front.

It is possible to calibrate nearly every thermometer with

the dierent inserts, even contact (TC, Pt, surface) or non-contact (infrared) thermometers.

The calibration temperature, adjusted simply using two keys on the controller, can be very quickly controlled. The actual and set temperature can be displayed simultaneously on a large 4-digit, high-contrast LC display. Thus reading errors are virtually eliminated.

Inserts and their applications

The insert has several bores into which the thermometer

being calibrated and one of the additional customer reference thermometers, for comparative calibration, can be inserted. The block is either heated or cooled to the desired calibration temperature. Once a stable temperature has been reached, the temperature probes to be calibrated can be compared with the reference thermometer. The documentation of this comparison represents the calibration.

Angled probes, large-diameter probes or probes with special designs cannot be calibrated with a dry-well calibrator. For this reason the temperature multi-function calibrator also has the possibility to function as a stirred liquid bath. The liquid is circulated by a magnetic stirrer and thus provides very good temperature distribution within the bath. The liquid used is chosen depending upon the desired calibration temperature.

The measuring spot of the pyrometer being calibrated must be smaller than the diameter of the infrared insert.

The sleeve has been specically manufactured with

regard to its design and surface in order to achieve a

dened emissivity for the measurement.

The calibration of surface temperature probes is very

dicult and not fully dened. Temperature probes

mounted on surfaces dissipate heat from the surface and create a cold zone on the surface being measured. In the temperature multi-function calibrator, the calibration temperature is created in a specially designed surface insert and an external reference thermometer measures the temperature directly under the surface.

Angled temperature probes are supplied to match the inserts.
