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. The IR thermometer features adjustable emissivity and a spot/distance ratio of 8:1. The meter calculates the temperature difference between IR surface temperature and dew point. Ideal for spotting potential areas with mold. Other features include data hold, programmable auto power off and a retractable probe that protects the sensors when the meter is not in use. IR temperature is measured by depressing button on keypad area of unit.
Requires special Extech cable if integration with AstroMC PC driver is desired. Order cable separately (our Item # 1208) or in the RH405 kit. You may require an RS-232/USB adapter for your PC configuration which is available in the Accessories and Supplies section of this site. We recommend our part #1301 or #1302, each of which comes with its own set of hardware level drivers.
Includes hard case and four AAA batteries. Can be used to measure sky temperature and therefore detect cloud cover. Not weatherproof.
