The HD2124.1 and HD2124.2 are portable instruments with two inputs and large LCD display. They perform measurements of absolute, relative and differential pressure, and temperature.
The PP471 electronic module is used to measure the pressure. The PP471 electronic module works as an interface between the instrument and the TP704 and TP705 series Delta Ohm probes. The temperature is detected with immersion, penetration, contact or air Pt100 probe with SICRAM module or 4 wire direct Pt100 probe.
The temperature probes are fitted with SICRAM module and the factory calibration settings are already memorized inside. Upon turning on the instrument automatically detects them.
The HD2124.2 instrument is a datalogger. It memorizes up to 32, 000 samples which can be transferred from the instrument connected to a PC via the multi-standard RS232C serial port and USB 2.0. The storing interval, printing, and baud rate can be configured using the menu.
The HD2124.2 model is also fitted with an RS232C serial port and can transfer the acquired measurements in real time to a PC or to a portable printer.
The Max, Min and Avg function calculate the maximum, minimum or average values, the Peak function detects the presence of pressure peaks, the A-B function calculates the difference of the pressures or temperatures measured by the
two inputs A and B. Other functions include: the relative measurement REL, the HOLD function, and the automatic turning off that can also be disabled.
The instruments have IP67 protection degree.
