Specification

The HD2301.0 is a portable instrument with a large LCD display. It measures rela-tive humidity and temperature using a Pt100 sensor or thermocouple humidity/temperature combined probe. Temperature only is measured by immersion, pen-etration or contact probes. The sensor can be a Pt100, Pt1000 or Ni1000.When the humidity/temperature combined probe is connected, the instrument calculates and displays the absolute humidity, the dew point, the partial vapour pressure.The probes are fi tted with an automatic detection module, with the factory calibra-tion settings already being memorized inside. 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 IP67 protection degree.
