HD2178 – Thermocouple – Pt100 Thermometer Data Logger
Brand: Delta OHM S.R.L.
HD2178.1 and HD2178.2 are portable instruments with a large LCD display.
These instruments measure temperature by means of immersion, penetration, contact or air probes with Pt100, Pt1000 or thermocouple probes.
You can connect a 3 or 4 wires Pt100 sensor or a 2 wires Pt1000 sensor to B input, a K, J, T, N, E type thermocouple to input A.
Probes to B input, a 8-poles DIN45326 connector, are equipped with an automatic detection module, with the factory calibration settings already being memorized inside.
A input is equipped with a miniature female polarized connector for thermocouple probes.
The instrument HD2178.2 is a data logger; it stores up to 80.000 samples that can be transferred to a PC when connected to the instrument through a RS232C serial port or a USB 2.0 port.
It is possible to configure the storage interval, the printing and the baud rate or to a portable printer by the menu.
Functions Max, Min and Avg calculate maximum, minimum and average values.
Further functions are: REL relative measure, HOLD and automatic switching-off system (excludable).
Instruments have IP66 protection degree.
