Extech WB200 Wet Bulb Hygro-Thermometer Datalogger

DISCONTINUED ITEM

Portable Hygro-Thermometer with Wet Bulb and Dew Point Temperature readings. This meter combines traditional dry/wet bulb operation with modern electronic circuitry to provide accurate readings and trouble-free operation especially in dusty environments. For hanging or bench-top use, the meter is ideal for greenhouses, paint booths, food processing, and other environmentally sensitive locations.

• 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)
• Resolution: 0.1°F/°C and 0.1%RH
• Basic accuracy: ±1°F/±0.6°C; ±3%RH
• Audible and visual alarm alerts when temperature and humidity level is higher or lower than the user programmed High/Low set points
• Two thermistors provide fast and accurate readings
• Dual color LED indicator for datalogging (Green) and alarm (Red) modes
• Datalogger stores100 records that can easily be recalled on meter display
• User programmable datalogging sampling rate from 15 to 60 minutes in 5 minute increments
• Water and Dust resistant construction, Low battery indicator
• Complete with four AAA batteries and 100-240V Universal AC adaptor

Ideal for greenhouses, paint booths, food processing, and other environmentally sensitive locations.

• LCD Display: 7-segment digit type for readings and messages. Function icons above and below reading for units and mode status.
• LED Status Indicator: Flashes red in an Alarm condition; Flashes green when a reading is logged
• Audible Alert: Sounds intermittently when in an Alarm condition
• Response Time: 120 second update rate
• Temperature Units: Switchable Temperature units (° C/° F)
• Measurement Ranges: Temperature (air, wet bulb, dew point): 41 to 122° F (5 to 50° C) Relative Humidity: 0.0 to 99.9%
• Resolution: 0.1° C/F (air, dew point, and wet bulb temperature) 0.1% Relative Humidity
• Accuracy: RH: ± 3% (10 to 90%RH @ 25° C; ± 5% outside of this range) Air, Dew Point, and Wet Bulb Temperature: ± 1° F (0.6° C)
• Datalogger Memory: Up to 100 reading sets (each set includes one measurement from each of the four measurement modes). Recall readings directly on the meter’s LCD display. The internal memory is non-volatile.
• Datalogging Sample Rate: Programmable from 15 to 60 minutes in 5 minute increments
• Over Range Indication: “E3” appears on the LCD
• Under Range Indication: “E2” appears on the LCD
• Low Battery Indication: Empty battery symbol appears on the LCD ( )
• Power Supply: Four (4) 1.5V ‘AAA’ batteries or 5V universal power adaptor (included)
• LCD Dimensions: 0.94(H) x 1.58’’ (W) / (24 x 40 mm)
• Meter Dimensions: 2.8 (top cover) x 3.1 (bottom cover) x 7.0 (H)’’ (70.8 x 77.6 x 177mm)
