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 CTD9100 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.

The new instrument concept brings together a stable heat source with precision Pt100 temperature measurement. This enables industrial temperature probes to be calibrated even more efficiently.

Regular monitoring of temperature probes helps to recognise failures promptly and shorten downtimes.

Easy to use

The temperature dry-well calibrators of the CTD9100 series work with temperature-controlled metal blocks and interchangeable inserts.

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

Thermometers with different diameters can be fitted into the calibrator using inserts, drilled to suit.

A new block design, with improved temperature homogeneity at the calibrator’s lower range, leads to smaller measurement uncertainties. The large insertion depth of 150 mm considerably reduces heat dissipation errors.

Model CTD9100-650

Temperature range from 40 ... 650 °C (104 ... 1.202 °F) This is the high-temperature model. This also works with an electrical resistance heating. When it comes to testing at high temperatures, such as for exhaust gases measurements

on test benches or in power generation, the model CTD9100-650 is the right choice.
