portable measuring device for temperature and pressure | HD21...

general information:

These measuring devices are portable instruments with a large LCD display. They measure absolute, relative and differential pressure, as well as temperature.

Pressure is measured using an internal module which differentiates from the atmosphere by a fixed final value. With the PP471 module acting as an interface, the instrument can be connected to all the Delta Ohm probes of the series TP704 and TP705. The internal module of HD2114B.0 and HD2114B.2 measures the barometric pressure.

The temperature is detected by using immersion, penetration, contact or air probes, with SICRAM module or directly with 4 wire probes. The sensor is available in the contruction types Pt 100 or Pt1 000. Factory calibration data are stored inside of temperature probes equipped with SICRAM module, so that they can easily be retrieved when the instrument is connected.

The instruments HD2114.2, HD2134.2, HD2164.2 and HD2114B.2 are dataloggers. They store up to 36,000 samples which can be transferred to a PC via the RS232C and USB 2.0 serial ports. The storing interval, printing, and baud rate can be configured using the menu. The devices can transfer the acquired measurement data in real time to a PC or to a portable printer (p.e. the HD40.1) with the helb of the RS232C serial port.

Via the functions Max, Min and Avg the maximum, minimum or average values can be calculated. The Peak function can be activated by connecting external probes to the module PP471. It is used to detect the presence of pressure peaks. Other functions include: the relative measurement REL, the HOLD function, and the automatic turning off which can also be excluded. The instruments have protection degree IP66.
