INTRODUCTION
The
HD2101.1
and
HD2101.2
are portable instruments with a large LCD display. They measure
relative humidity and temperature using a Pt100 sensor or thermocouple humidity/temperature
combined probe. Temperature only is measured by immersion, penetration or air contact probes.
The sensor can be a Pt100, Pt1000 or Ni1000.
When the combined humidity/temperature probe is connected, the instrument calculates and
displays the absolute humidity, the dew point, the partial vapour pressure, and the
comfort indices
.
The probes are fitted with automatic detection module, with the factory calibration settings already
being memorized inside.
The HD2101.2 instrument is a
datalogger
. It memorizes up to 38,000 samples which can be
transferred from the instrument connected to a PC via the RS232C serial port or USB 2.0 port. The
storing interval, printing, and baud rate can be configured using the menu.
The HD2101.1 and HD2101.2 models are fitted with an RS232C serial port and can transfer the
acquired measurements in real time to a PC or to a portable printer.
The Max
,
Min
and
Avg function calculate the maximum, minimum or average values.
Other functions include: the relative measurement REL, the HOLD function, and the automatic
turning off that can also be disabled.
The instruments have IP66 protection degree.
This manual describes the HD2101.1 and HD2101.2 models: if not otherwise specified, the
description is intended to be applicable to both models.
