DIGITAL MANOMETER THERMOMETER 

HD2304.0 Manometer-Thermometer, input for SICRAM module PP471 to connect probes TP704 and TP705 series. Temperature measurement with Pt100 probe complete with SICRAM module, measuring range -200°C +650°C. Storage of maximum, minimum, average value.
Functions: REL, HOLD and auto power off which can be disabled, IP 67 protection degree.

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.
