Description
DOCUMENTS

Ideal for monitoring humidity and temperature levels in offices, factories, warehouses, storage rooms, freezers, shipping vans, and during flood restoration, the WB200 combines traditional dry/wet bulb operation (refillable water tank) with electronic circuitry to provide accurate readings and trouble-free operation, especially in dusty environments. A built-in fan provides the fast response time. Audible and visual alerts for temperature and humidity levels higher or lower than the user programmed High/Low set points. Datalogger featuring user programmable sampling rate (15 to 60 minutes) stores 100 records that can easily be recalled on the display. Measures Wet Bulb, Dew Point, Temperature (41°F to 122°F /5°C to 50°C) and Relative Humidity (0.0 to 99.9%RH). Comes with four AAA batteries, 100-240-Volt Universal AC adapter, and user manual.
