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. ±0.8°C (-10…+80°C) 0…80°C Clean air, RH<80% Approx. 20 hours @ 20 m/s with Approx. 30 hours @ 5 m/s with alkaline batteries alkaline batteries Unit of Measurement Speed Flow rate Pipeline section for flow rate calculation Cable length m/s – km/h – ft/min – mph – knot l/s - m3/s - m3/min - m3/h - ft3/s - ft3/min 0.0001…1.9999 m2 ~2m (*) It’s referred to all the probes except the hot wire ones, which autonomy is stated in the next pages INSTRUMENT TECHNICAL CHARACTERISTICS Instrument Dimensions (Length x Width x Height) 140x88x38mm Weight 160g (complete with batteries) Materials ABS Display 2x4½ digits plus symbols Visible area: 52x42mm Operating conditions Operating temperature Storage temperature Working relative humidity Protection degree -5…50°C -25…65°C 0…90%RH without condensation IP67 Power supply Batteries 3 1.5V type AA batteries Autonomy (*) 200 hours with 1800mAh alkaline batteries Power absorbed with instrument off < 20μA Measuring unit °C - °F - m/s - km/h - ft/min - mph - knot - l/s m3/min - m3/h - ft3/s - ft3/min ±0.8°C (-10…+80°C) 0,1 m/s AP472S1… AP472S2… AP471S3 AP471S2 AP471S1 AP472S4… Air speed 125 Air speed Speed
