The built-in microprocessor circuit assures excellent performance and accuracy. The HHF81 can track the maximum and minimum values along with current readings. The HHF81 displays the flowrate in your choice of knots, meters per second, kilometers per hour, miles per hour, or feet per minute.\u003cbr\u003e \u003cbr\u003e The HHF81 relies upon a low-friction ball bearing mounted wheel design to provide high accuracy at high and low air velocity. The impeller provides excellent accuracy (±3 to 4%) and the ability to measure the slightest breeze (0.3 m\/s). For temperature readings, the HHF81 has an internal thermistor or is compatible with any Type K thermocouple with SMP Male connector, and is accurate to ±1°C + 1% of reading. The humidity sensor measures to 95% relative using a high precision thin-film capacitance sensor with fast response to humidity changes. The Light measurement utilizes an exclusive photo diode and color correction filter light sensor.\u003cbr\u003e \u003cbr\u003e \u003cb\u003eSPECIFICATIONS\u003c\/b\u003e\u003cbr\u003e \u003cb\u003eAIR VELOCITY\u003c\/b\u003e\u003cbr\u003e \u003cb\u003eMeasurement Range:\u003c\/b\u003e 80 to 5910 ft\/min, 0.4 to 30.0 m\/s, 0.9 to 67.0 mph, 1.4 to 108.0 km\/hr, 0.8 to 58.3 knots, 0.8 to 58.3 knots\u003cbr\u003e \u003cb\u003eResolution:\u003c\/b\u003e 1 ft\/min, 0.1 m\/s, 0.1 mph, 0.1 km\/hr, 0.1 knots\u003cbr\u003e \u003cb\u003eAccuracy:\u003c\/b\u003e \u003cbr\u003e    \u003cb\u003e≤20 m\/s:\u003c\/b\u003e 3% FS\u003cbr\u003e    \u003cb\u003e\u0026gt;20 m\/s:\u003c\/b\u003e 4% FS\u003cbr\u003e \u003cb\u003eTEMPERATURE (Internal Thermistor)\u003c\/b\u003e\u003cbr\u003e \u003cb\u003eMeasurement Range:\u003c\/b\u003e 0 to 50°C (32 to 122°F)\u003cbr\u003e \u003cb\u003eResolution:\u003c\/b\u003e 0.1°C\/°F\u003cbr\u003e \u003cb\u003eAccuracy:\u003c\/b\u003e ±1.2°C (±2.5°F)\u003cbr\u003e \u003cb\u003eOperational Temperature:\u003c\/b\u003e 0 to 50°C (32 to 122°F)\u003cbr\u003e \u003cb\u003eTEMPERATURE (External Type K Thermocouple)\u003c\/b\u003e\u003cbr\u003e \u003cb\u003eMeasurement Range:\u003c\/b\u003e -100 to 1300°C (-148 to 2372°F)\u003cbr\u003e \u003cb\u003eResolution:\u003c\/b\u003e 0.1°F\/°C\u003cbr\u003e \u003cb\u003eAccuracy:\u003c\/b\u003e ±(1% + 1°C) of rdg [±(1% + 2°F) of rdg]\u003cbr\u003e \u003cb\u003eHUMIDITY\u003c\/b\u003e\u003cbr\u003e \u003cb\u003eMeasurement Range:\u003c\/b\u003e 10 to 95%\u003cbr\u003e \u003cb\u003eResolution:\u003c\/b\u003e 0.1%\u003cbr\u003e \u003cb\u003eAccuracy:\u003c\/b\u003e\u003cbr\u003e    \u003cb\u003e\u0026lt;70% RH:\u003c\/b\u003e ±4% of rdg\u003cbr\u003e    \u003cb\u003e≥70% RH: \u003c\/b\u003e±(4% rdg + 1.2 % RH)\u003cbr\u003e \u003cb\u003eOperational Humidity Max.:\u003c\/b\u003e 80% RH\u003cbr\u003e \u003cb\u003eLIGHT LUX\u003c\/b\u003e\u003cbr\u003e \u003cb\u003eMeasurement Range:\u003c\/b\u003e 0 to 2200 Lux, 1800 to 20000 Lux, 0 to 204.0 Fc, 170 to 2000 Fc\u003cbr\u003e \u003cb\u003eResolution:\u003c\/b\u003e 1 Lux, 10 Lux, 0.1 Ft-cd, 1 Ft-cd\u003cbr\u003e \u003cb\u003eAccuracy:\u003c\/b\u003e ±(5% rdg +8 dgt)\u003cbr\u003e \u003cb\u003eOverange Display:\u003c\/b\u003e “----”\u003cbr\u003e \u003cb\u003eBattery:\u003c\/b\u003e 9V (included)\u003cbr\u003e \u003cb\u003ePower Consumption:\u003c\/b\u003e Approx.
