DIGITAL THERMOMETER 

HD2128.1 Thermocouple thermometer for probes type K, J, T, R, N, S, B, E measuring range –200°C +1370°C, two inputs, large display. Storage of maximum, minimum, average value and the difference between the two inputs, RS232 C output for data transfer in real time to a PC or printer.
Functions: REL, HOLD and auto power off which can be disabled, IP 67 protection degree.
HD2128.2 Thermocouple thermometer for probes type K, J, T, R, N, S, B, E, two inputs, large display. Datalogger which stores maximum, minimum, average value, it can store up to 38.000 couples of samples. RS232C/USB output for data transfer in real time to a PC or printer.
Functions: REL, HOLD and auto power off which can be disabled, IP 67 protection degree.

The HD2128.2 instruments are data loggers. The memorizes 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 configured using the menu.

All the models 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 HD2128.1 and HD2128.2 calculate the A-B difference of the temperatures captured by the two input channels.
