HHF80 4IN1 Anemometer - thermometer, anemometer, hygrometer and photometer

The HHF81 anemometer can measure flow of air, moisture, temperature and light. The built-in microprocessor circuit ensure excellent performance and precision. The HHF81 can track of the maximum and minimum values along with the current readings. The HHF81 and HHF82 show the flow rate according to your choice of knots, feet per second, kilometers per hour, miles per hour or feet per minute.
The HHF81 and HHF82 used a design of wheel mounted on a low-friction bearing to provide high precision at high and low air speeds. Impeller offers excellent accuracy (3 to 4) and the ability to measure slight Breeze (0.3 msec.). For the temperature readings, the HHF81 has an internal thermistor or is compatible with any K-type thermocouple with SMP connector, with an accurate reading of ±1 ° C 1. The humidity sensor measures up to 95 of relative humidity using a sensor of capacitance of thin film of high precision with rapid response to changes in humidity. The light metering uses exclusive color correction and photodiode filter light sensor.
