This 4 in 1 environmental meter is an anemometer, hygrometer light meter and thermometer in one. Measure air velocity temperature, light, and humidity in one compact device. The thermometer uses type K (NiCr-NiAl) thermocouple input jack. The Humidity is measured by a high precision thin-film capacitance sensor. Light is measured with a photo diode and color correction filter. Includes carrying strap. Uses 9V battery not included.
