Product Description

EasyMeasures EM-HD2328.0 with two inputs is a portable instrument with a large LCD display. It
measures temperature by means of immersion, penetration, contact or air probes. Its
sensor can be a K, J, T or E thermocouple type.
Functions Max, Min and Avg calculate maximum, minimum and average values.
Further functions are: REL relative measure, HOLD, automatic excludable switchingoff
system and the A-B difference of the two input channels.
The instrument has IP67 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.

(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.
