Portable thermo-hygrometer for relative humidity and temperature

HD2301.0

Portable thermo-hygrometer for relative humidity and temperature, with 0 ... 100%RH, Pt100/Pt1000 temperature input, dew point, g/m3 and hPa calculations, LCD display and IP67 protection.

Introduction

For mobile checks of air conditions, reliable display and probe handling matter as much as the measurement itself. This portable meter measures relative humidity and temperature with combined probes and shows the values on a large 52 x 42 mm LCD, making readings easy to follow during routine inspections.
 
One instrument also covers temperature-only tasks with Pt100 or Pt1000 immersion, penetration, air or contact probes. With a combined probe connected, it calculates absolute humidity, dew point and partial vapor pressure, giving you the key climate values without manual conversion.
 
Daily work stays simple: SICRAM probes are detected automatically and carry factory calibration data, while MAX, MIN, AVG, REL and HOLD functions support quick checks on site. The IP67 instrument protection, 160 g weight and up to 200 hours of battery autonomy make it a practical choice for portable measurement work.

Clear display
Large 52 x 42 mm LCD shows two 4½-digit rows plus symbols for easy reading.
Smart probe handling
SICRAM probes are detected automatically with factory calibration data stored inside.
Protected for mobile use
IP67 instrument protection supports portable measurement in demanding conditions.
Long battery autonomy
Three AA batteries provide up to 200 hours with 1800 mAh alkaline cells.

Features

Humidity and temperature measurement

The instrument works with combined probes for relative humidity and temperature and calculates dew point, absolute humidity and partial vapor pressure.

Temperature probe input

Temperature-only measurements use Pt100 or Pt1000 immersion, penetration, air or contact probes through the 8-pole DIN45326 input.

Measurement functions

MAX, MIN and AVG capture session values. REL displays the difference from a reference value, and HOLD freezes the current reading.

Probe configuration

SICRAM probes are recognized at power-up. Direct Pt100 and Pt1000 probes can be configured through the probe type menu

Selectable units

The display can show %RH, g/m3, hPa, Td and temperature in °C or °F.
