Description

The all-purpose model CTH6500 hand-held thermometer, for
superior mobile temperature measurement, is notable for its

precision, exibility and ease of handling.

In addition to Pt100 resistance thermometers, it can
also process signals from typical thermocouples. Thus
temperatures from -200 ... +1,500 °C (-328 ... +2,732 °F)
can be measured. The explosion proof version is only for
measuring Pt100 resistance thermometers available.

Through its high accuracy of 0.03 K in ranges from

-100 ... +150 °C (-148 ... +302 °F), this instrument can
also be used as a reference instrument in biotechnology,
pharmaceutical and food industries. The CTH6500 is thus
also ideal for all service and maintenance tasks.

Hand-held thermometer model CTH6500

In this way it is possible to reduce measuring errors to a
minimum and ensure a high display accuracy.

Additional elds of application

The instrument has been primarily designed for temperature
measurement, though it can, with the appropriate probes,
also be used for:

■

Humidity measurement with a combined temperature­humidity probe

■

Flow measurement from 0.1 ... 40 m/s with a vane sensor

The calibration and adjustment possibilities above are also
applicable to these measurement parameters.

Low-drift measuring ampliers ensure small measurement

errors, while easy-to-use adjustment features considerably
simplify adjustments and calibrations:

■

Calibration by code for fast setting of standard probes via

identication numbers

■

Physical calibration of probe and display at one, two or

three dierent temperatures
