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 configured using the menu.
The models HD2178.1 and HD2178.2 are fitted 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.
