Portable Micromanometer-Thermometer Data Logger with 20mbar built-in sensor. It performs measure of absolute, relative, differential pressure and temperature. In order to measure the pressure you use the electronic module PP471 that works as an interface between the instrument and Delta OHM probes series TP704 and TP705. Temperature is measured by means of Pt100 with SICRAM module or direct 4 wires Pt100 probes for immersion, penetration, contact or air. Temperature probes are equipped with SICRAM module and factory calibration data are stored inside. Measuring range -200°C +650°C. Datalogger which stores the maximum, minimum, average value and can store up to 36,000 couples of samples. USB output for data transfer in real time to a PC. Functions: REL, HOLD, PEAK (with probes TP704 or TP705), auto power off which can be disabled, IP 66 protection degree.
