Features:Handheld infrared thermometer for non-contact temperature measurement of objects. Adjustable emissivity; data hold function; the temperature of the optional units: C ( C) and Fahrenheit ( F). PM6530A&B can set the upper and lower limit alarm: when the measured value is greater than the ambient temperature + HAL value or less than the ambient temperature + LAL value, the red indicator will light up. PM6530D can display the ambient temperature, ambient humidity, dew point temperature, emissivity and surface temperature at the same time. PM6530D can insert K thermocouple for temperature contact measurement. PM6530D can be used to determine whether the measured object is moldy according to the difference between the surface temperature and the dew point temperature. PM6530D with UV lamp can be used to detect leakage of vehicle air conditioning and other high pressure systems. Color LCD display for fast and easy reading. Compact size and light weight, with a storage bag, easy to carry.
