HD 2303 Thermo-Anemometer

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 hotwire 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 chosen from the Pt100, Pt1000.  The probes are equipped with the SICRAM module, with the factory calibration data stored 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 excluded.  The instruments have IP67 protection degree.
