Optional Temperature Probe (Pt-1000 ohm RTD)

Measures 11 environmental conditions including light|Accurately measure air velocity, airflow, temperature, humidity, wet bulb, dew point, heat index, windchill, barometric pressure, altitude, and light|Auto-rotating, dual-line LCD with backlight for easy reading in low light|Operational modes include auto-off and low-battery indicators, MIN/MAX, and data hold|Versatile anemometer uses a low-friction vane and displays air velocity measurements in five units. High-precision humidity sensor provides a quick response time to make accurate calculations for wet bulb, dew point, heat index and windchill readings. Dual-line display simultaneously shows relative humidity and temperature, or air velocity and temperature. Optional external high-accuracy temperature probe expands the measurement range to 14 to 212F (-10 to 100C).
