DIGITAL ANEMOMETER THERMOMETER 

HD2303.0 Anemometer Thermometer for air speed measurement which use hot-wire or vane probes with SICRAM module, for temperature Pt100 sensor for probes input with SICRAM module, measuring range –200°C +650°C. Storage of maximum, minimum, average value.
Functions: REL, HOLD and auto power off which can be disabled, IP 67 protection degree.

The HD2303.0 is a portable instrument with a large LCD display.
It is designed for use in the fields of air conditioning, heating, ventilation and environmental comfort.
It uses hot-wire or vane probes to measure air speed, flow rate, and temperature inside pipelines and vents.
Temperature only is measured by immersion,penetration or air contact probes.
The temperature sensor used can be chosenfrom the Pt100, Pt1000.

The probes are fitted with the SICRAM module, with the factory calibration 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.
