AV90 anemometer SPECIFICATIONS AIR VELOCITY Mounting Nut: 1/4" x 20 Operating Temperature: Meter: 0°C to 50°C (32F to 122°F) Vane: 0°C to 60°C (32F to 140°F) WIND VELOCITY Units Resolution Threshold TEMPERATURE Temperature Scale: Celsius or Fahrenheit user selectable Temperature Sensor: NTC Measurement Range: -20°C to 60°C / -4°F to 140°F Measurement rate: 1 times per second. This meter displays temperature (°C or °F) and airflow at the same time. Maximum and minimum figures for flow measurements, up to 8 readings can be taken and automatically averaged. and temperature can be shown. For more accurate In addition, measurements can be taken over either 2 or 16 seconds with the average of 2 or 16 readings being displayed. Airflow measurement can be displayed as: metres/second, feet/minute, knots, mph, kph. x Simultaneous display of both temperature and air speed. Low battery indication Accuracy: Stated accuracy at 23°C ± 5°C, <80% relative humidity Operating environment: 0°C to 50°C at <75% relative humidity Storage environment: -20°C to 55°C at <80% relative humidity Memory of maximum, minimum and average record for both temperature and wind speed.
