rh401:digital psychrometer + infrared thermometer

humidity, wet bulb, dew point, air temperature plus non-contact ir temperature

• triple display with backlighting
• displays air temp+rh+surface temp or dew point+rh+surface temp or wet bulb+rh+surface temp
• built-in infrared thermometer with laser pointer and 8:1 distance to target ratio
• adjustable emissivity from 0.3 to 1.0
• precision humidity capacitance sensor is retractable for protection during transportation and storage
• calculates t1 (ir surface temperature) - dp (dew point) differential
