Keterangan
The HD2178.1 and HD2178.2 are portable instruments with a large LCD display.
They measure the temperature using immersion, penetration air or contact probes with RTD or thermocouple sensor. A 3 or 4 wire Pt100 sensor or a 2 wire Pt100 sensor can be connected to the input B, while a thermocouple of type K, J, T, E, N to the input A.The probes for input B, 8 poli DIN45326 connector, are equipped with automatic detection module with the factory calibration settings already being memorized inside. A miniature polarized connector for thermocouple is provided for input A. The instrument HD2178.2 is a datalogger which stores up to 80,000 samples. These data can be transferred from the instrument connected to a PC via the multi-standard RS232C serial port and USB 2.0. The storing interval, printing, and baud rate can be confi gured using the menu.The models HD2178.1 and HD2178.2 are fi tted 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. Other functions include: the relative measurement REL, the HOLD function, and the automatic turning off that can also be disabled. The instruments have IP67 protection degree.

Accuracy of the thermocouple probes:
The tolerance of a type of thermocouple corresponds to the maximum acceptable shift from the e.m.f. of any thermocouple of that type, with reference junction at 0°C. The tolerance is expressed in degrees Celsius, preceded by the sign. The percentage tolerance is given by the ratio between the tolerance expressed in degrees Celsius and the measurement junction temperature, multiplied by one hundred. The thermocouples conforming to regulations must comply with one of the following tolerance levels, the values of which are reported in the table.
G I (special tolerances)
G II (normal tolerances)
The tolerances refer to the operating temperature expected for the thermocouple, in agreement with the thermoelements’ diameter.
