Manometer - Thermometer

Model  Description 
HD 2304.0  Manometer-Thermometer with one input

The HD2304.0 is a portable instrument with a large LCD display. It performs 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 probes with SICRAM module or 4 wire direct Pt100 probes.
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 Max, Min and Avg function calculate the maximum, minimum or average values.
Other functions include: the relative measurement REL, the HOLD function, and the automatic turning off
that can also be disabled.
