HD 2178.1, HD 2178.2 – Pt100 and Thermocouple double Input Thermometers

HD2178.1 and HD2178.2 are portable instruments with a large LCD display. These
instruments measure temperature by means of immersion, penetration, contact or
air probes with Pt100 or thermocouple probes. You can connect a 3 or 4 wires Pt100
sensor or a 2 wires Pt1000 sensor to B input, a K, J, T, N, E type thermocouple to
input A. Probes to B input, a 8-poles DIN45326 connector, are equipped with an
automatic detection module, with the factory calibration settings already being
memorized inside. A input is equipped with a miniature female polarized connector
for thermocouple probes. The instrument HD2178.2 is a data logger; it stores up to
80.000 samples that can be transferred to a PC when connected to the instrument
through a RS232C serial port or a USB 2.0 port. 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 switching-off system, excludable.

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.

(1) Materials for thermocouples are generally supplied so to comply with the factory tolerances specified in the table for temperatures over -40°C. However these materials can sometimes not comply with the factory tolerances for the low
temperatures reported under Class 3, for thermocouples of T, E, K and N type, when thermocouples have to comply at the same time the limits of Class 3 and Class 1 and/or Class 2.
