Hand Held Instrument for Temperature : UM RTD.2


Possible areas of application

Digital universal temperature hand-held instrument for use with Pt100 exchangeable sensors.


Sensors and probes

The high accuracy of the signal detection and processing is achieved by means of powerful sensors with electronic linearisation of the characteristic curve. The correct probes are available for a wide range of measuring tasks.

Operating comfort

The innovative design of the attractive housing and the advanced technology make the sensors comfortable to operate. In mobile use, all functions can be selected and carried out easily by pressing the buttons. The membrane keypad guarantees protection against dust and moisture.

Multi-function display

As well as MIN / MAX values, hold function and the selected unit of measurement, various calculation values, such as temperature differential, pressure differential, dew point or heat capacity can also be shown on the multi-function display.


Automatic sensor recognition through standard DIN socket provides a plug-&-play solution that is easy to install.

Customer-specific curve

With this function, customer-specific curves can be used, alongside the standard calculation of the resistance / temperature characteristic curve in compliance with EN 60751.

The UM RTD.2 has a very high accuracy of measurement. In order to be able to exploit this high degree of accuracy, appropriate high-quality temperature sensors must be used. Various standard classes of accuracy are available for this purpose.

For applications that require a very high degree of accuracy which is higher than the accuracy of the sensor itself, it is recommended that the sensor be calibrated by means of a user-defined characteristic curve.

To perform the calculation the calibrated actual values of the sensor are determined and compared with the actual temperatures in a calculation table. On the basis of these reference points the sensor curve is calculated with a mathematical function and stored in the gauge. The UM RTD.2 can store 10 value pairs.

PC Interface

To transfer the measurement values and stored values to a PC, the majority of the instruments are fitted with a serial interface. The software packages are available with extensive recorder and display functions, also for evaluation of the logged and alarm values. Process sequences can then be monitored and analysed clearly using the measurement procedures recorded and visualised as well as all data can be exported into standard programs e.g. Excel.

Time displays

All data can be displayed with the year and date, thanks to the real time clock.
