Extech RH401 Triple Display Hygro Thermometer Psychrometer with Built in Infrared Thermometer

Description

Thermohygrometer simultaneously displays relative humidity, surface temperature and air temperature, dew point, or wet bulb on a triple LCD with backlighting. IR thermometer features a built-in laser pointer, adjustable emissivity of 0.3 to 1.0 and a spot/distance ratio of 8:1. The meter calculates the temperature difference between IR surface temperature and dew point. Other features include data hold, programmable auto power off, low battery indicator, over/under range alert and a retractable probe that protects the humidity sensors when not in use. Optional RS-232 cable (37803-31) allows downloads onto PC via Windowsr Hyper Terminal utility. Meter can be calibrated in the field with using optional RH calibration standard salt bottles. Monitor relative humidity, temperature, wet bulb, and dew point IR thermometer allows quick non-contact surface temperature measurements. Meter can be calibrated in the field using optional salt standards
Item is a Class II laser product, 1mW power output.
Built-in IR thermometer with laser pointer measures surface temperature from -40 to 932°F (-40 to 500°C)
Displays air temperature, humidity and surface temperature or dew point, humidity and surface temperature or wet bulb, humidity and surface temperature on a triple LCD with backlighting
Calculates the temperature difference between IR surface temperature and dew point
Can locate potential mold problems by spotting surface temperatures below the dew point
