The HD2124.1 and HD2124.2 are portable instruments with a 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 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 that can be
transferred from the instrument connected to a PC via the RS232C serial port or USB 2.0 port. The
memorization interval, printing, and baud rate can be configured using the menu.
The HD2124.1 and HD2124.2 models are 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 IP66 protection degree.
