Hand-held instrument for Temperature : MH 3750

SKU MH 3750

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.


Extensive alarm functions via the display and buzzer, freely scalable standard signal output and PC interface are available.

Data storage (Log functions)

Some instruments in the MH range can store data. The integrated memory records up to 16 200 measurement values. The date and time is automatically added to the values. A real time clock is integrated for this purpose.

Two log functions are available:

  • In the STORE mode, data is transferred by means of pressing a button and 99 records can be stored. The values stored are shown directly on the display.
  • In CYCLE operation, values are recorded automatically at a pre-programmed interval. Up to 16 200 records can be stored. The stored values are shown on a PC.

PC Interface

To transfer the measurement values and stored values to a PC, the majority of the MH instruments are fitted with a serial interface. The EBS 20 M software packages are available with extensive recorder and display functions, as is the SOFT 3050 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.

Alarm- & time displays

A visual and acoustic warning signal indicates when measurements exceed or fall below a programmed alarm point. Transmission via PC is also possible. All data can be displayed with the year and date, thanks to the real time clock.


To confirm the outstanding accuracy for applications in the service sector, measurement and control workshops and in quality assurance, works or DKD certificates are available to you from our DAkkS laboratory.
