The handy and reliable instruments of the MH range are used for measuring and recording humidity, temperature or pressure. The MH range is very flexible and is equally suitable for simple measurements and special applications.
Sensors and probes
The high accuracy of the signal detection and processing is achived 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 differencial, pressur differencial, dew point or heat capacity can also be shown on the multifunction display.
Inputs
Automatic sensor recognition through standar DIN socket provides a plug-&-play solution that is easy to install.
Outputs
Extensive alarm functions via the display, freely scalable standard signal output and buzzer and RS 485 interface.
Data storage (log functions)
Some instruments in the MH range can store data. The integrated memory records up to 16200 measurements values.
The data 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. 1800, 2700 or 5700 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 witha serial interface.
The EBS9M software packages are available with extensive recorder and display functions, as is the SOFT3050 for evaluation of the logged values.
Process sequences can then be monitored and analysed clearly using the measurement procedures recorded and visualised, and 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.
User-defined characteristic curve MH3750
With this function, customer-specific curves can be used, alongside the standard calculation of the resistence/temperature characteristic curve in compliance with EN60751.
The MH3750 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 to the MH3750 by means of a user-defined characteristic curve.
Explosion protection
Hand held pressure measuring devices and pressur sensors are available in EXI versions (EEx ib IIC T4-03ATEX0136X).
