HHF81 4 IN 1 Air Velocity Humidity Light Temperature Meter 14021

The HHF81 anemometer can measure air flow, humidity, temperature and light. 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.

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.

• Simultaneous Readings of Air Velocity and Temperature or Humidity and Temperature

• Exclusive Photo Diode and Color Correction Filter Light Sensor, Spectrum Meets C.I.E. Photopic

• Standard Type K Thermocouple SMP Input Jack Suitable for All Types of K Probes

• Lux/Feet-Candle Selectable by Pressing Button on the Front Panel
