HD2128 Thermocouple Thermometer
Brand: Delta OHM S.R.L.
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 switching off system (excludable).
HD2128.1 and HD2128.2 calculate A-B difference of the temperatures acquired by the two input channels.
Instruments have IP66 protection degree.
