Hand-held instruments / Resistance thermometer

型號:Type MH 3750
  • Excellent measuring accuracy
  • optical and acoustic alarm
  • 2 integrated logger functions
  • user-specific sensor characteristic curve (50 interpolation points)
  • real-time clock with day / month / year
  • freely scalable analogue output
  • Digital universal temperature hand-held instrument for the use of Pt100 changeable sensors.

    The high accuracy in signal detection and processing is achieved by powerful sensors with electronic linearisation of the characteristic curve. For extensive measuring tasks, the appropriate sensors are available.

    The innovative design of the shapely housing as well as the advanced technology provide for comfortable handling. In mobile use, all functions can be conveniently selected and executed at the touch of a button. The membrane keypad ensures protection against dust and humidity.

    In addition to the MIN/MAX values, hold function and the selected units of measurement, various calculated values such as differential temperature, differential pressure, dew point or heat content can also be displayed on the multifunction display.

    The automatic sensor detection via standard DIN sockets offers a plug-and-play solution which is easily installed.

    Extensive alarm functions via display, freely scalable standard signal output as well as PC interface are available.

    Some instruments of the MH series can store data. The integrated memory records up to 16,200 measured values. The values are automatically tagged with date and time. A real-time clock is integrated for this purpose.

    Two logger functions are available:

    In STORE mode, data is stored at the push of a button, and 99 data sets can be stored. The stored values are made visible directly on the display.

    In CYCLE mode, an automatic recording is made at a previously programmed time interval. Depending on the device, up to 16,200 data sets can be stored. The stored values are made visible via PC.

    For the transfer of the measured and stored values to a PC, the majority of MH instruments are equipped with a serial interface. The software packages EBS20M with extensive recorder and display functions and SOFT3050 for the evaluation of logger and alarm values are available. The recorded and visualised measurement processes can then be used to clearly monitor and analyse process sequences, and all data can be exported to standard programs such as Excel.

    An optical and acoustic warning signal indicate exceeding or undershooting a programmed alarm point. The transfer via PC is also possible. Thanks to the real-time clock, all data can be displayed with year and date.
