Extech WB200

Ideal for monitoring humidity and temperature levels in a wide range of locations, the Extech WB200 combines traditional dry and wet bulb operation with electronic circuitry to provide accurate readings and trouble-free operation, especially in dusty environments. A built-in fan provides fast response time. It has audible and visual alerts for temperature and humidity levels higher or lower than the user programmed high/low set points. The datalogger featuring user programmable sampling rates (15 to 60 minutes) stores 100 records that can easily be recalled on the display. Measures wet bulb, dew point, temperature (5°C to 50°C / 41°F to 122°F), and relative humidity (0.0% RH to 99.9% RH). Comes with four AAA batteries, 100 V - 240 V universal AC adapter, and user manual.
