Extech HD500 psychrometer is capable of a number of temperature/humidity measurements. The built-in infrared thermometer is for non-contact surface temperature measurement of up to 932°F (500°C). The infrared thermometer has a 30:1 distance to target ratio. The type K temperature function uses a type K probe for contact measurements up to 2501°F (1372°C). Extech HD500 psychrometer also measures relative humidity with a range of 0 to 100%. Dew point and wet bulb measuring potentials. Above all, the instrument also measures water vapor in GPP (grains per poung)/g/kg (grams per kilogram). Extech HD500 psychrometer is completed with Windows ® compatible software with USB cable, Type K bead wire temperature probe (-58 to 482°F/-50 to 250°C), built-in stand, hard carrying case, and 9V battery.
