The 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 or air 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 HD2108.2 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 RS232C serial port or USB 2.0 port. The logging 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.
