HD 2108.1, HD 2108.2, HD 2128.1, HD2128.2 – Thermocouple Thermometers: K, J, T, N, R, S, B, E

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 logger, 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.

Product Description

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 logger, 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.
All models are equipped with RS232C serial port and are able to transfer the acquired
measures, in real time, to a PC or a portable printer.
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.
Instruments have IP66 protection degree.

Thermocouple probes accuracy:
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 tolerances refer to the operating temperature expected for the thermocouple, in
agreement with the thermo-elements’ diameter.
Those thermocouples that comply with the limits for temperatures over 0°C, do not
necessarily comply with the limits for ranges below 0°C.
