GENERAL CHARACTERISTICS
The Thermohygrometer Model HD2301.0 is a portable instrument that measures an
environment's temperature and relative humidity.
It is fitted with a large LCD display for excellent visualization of the measured data.
The Thermohygrometer Model HD2301.0 measures:
•
relative humidity and temperature using combined probes, fitted with a Pt100
temperature sensor or thermocouple;
•
temperature only by immersion, penetration, or contact probes. The sensor
can be a Pt100 or Pt1000.
When the combined humidity/temperature probe is connected, the instrument
calculates and displays the following data:
•
absolute humidity,
•
dew point,
•
partial vapour pressure.
The probes are fitted with the automatic detection SICRAM module, with the factory
calibration settings already being memorized inside.
The units of measurement are the following:
1.
%RH % of relative humidity
2.
g/m
3
Grams of vapour in a cubic meter of dry air
3.
hPa Partial vapour pressure (hPa)
4.
Td Dew point (°C or °F)
5.
°C/°F Temperature in Celsius (°C) or Fahreneit (°F) degrees.
Using the Max, Min and Avg function of this instrument respectively obtains the
maximum, minimum or average values.
Other available functions are:
•
the relative measurement REL;
•
the HOLD function;
•
the automatic turning off which can also be disabled.
