Thermocouple Thermometers
HD2108.1 and HD2108.2 with one input HD2128.1 and HD2128.2 with two inputsThe HD2108.1 and HD2108.2 with one input and the HD2128.1 and HD2128.2 with two inputs are portable instruments with a large LCD display.
They measure the temperature using immersion, penetration air or contact probes. The sensor may be a thermocouple of type K, J, T, N, R, S, B or E. The HD2108.2 and HD2128.2 instruments are dataloggers. The HD2108.1 memorizes up to 76,000 samples, the HD2128.2 up to 38,000 pairs of values. 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.All the models 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 HD2128.1 and HD2128.2 calculate the A-B difference of the temperatures captured by the two input channels. 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.
