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, air
or contact probes. The sensor may be a thermocouple of type K, J, T, N, R,
S, B or E.
Instruments HD2108.2 and HD2128.2 are data loggers, they store up to
76.000 samples the first and 38.000 couples of values the second. These
data can be transferred into a PC connected to the instrument through
the serial ports RS232C and USB 2.0. It is possible to configure the storage
interval, the printing and the baud rate by the menu.
Functions Max, Min and Avg calculate maximum, minimum and average
values.
Further functions are: REL relative measure, HOLD and automatic switchingoff system (excludable). HD2128.1 and HD2128.2 calculate A-B difference
of the temperatures acquired by the two input channels.
