The HD2103.1 and HD2103.2 are portable instruments with a large LCD display. They are designed for use in the fi elds of air conditioning, heating, ventilation and environmental comfort. They use hot-wire or vane probes to measure air speed, fl ow 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 fi tted with the SICRAM module, with the factory calibration settings already being memorized inside. The HD2103.1 and HD2103.2 models are fi tted 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. The instruments have IP67 protection degree.
