HT3320 digital thermometer is a professional meter for temperature measurements without contact thanks to its ergonomic “gun” shape using infrared rays. High accuracy is granted by a built-in laser pointer and a good Distance to Spot ratio of 50:1.


The instrument performs saving of JPG pictures and small 3GP videos into its internal memory or external micro SD card as well as temperature recordings with programmable time thanks to the internal data logger feature. All tests can be easily downloaded to a PC through the provided USB cable without any software. Other measurements which can be performed are air temperature/humidity with internal probe, dew point/wet bulb temperature and temperature with type K probe.


HT3320 permits to set MAX and MIN alarm thresholds on the whole range activating an alarm buzzer should these limits be exceeded. Data HOLD function freezes results on display. It is provided with a large backlighted LCD display for easier reading under critical conditions. The Auto Power Off function preserves internal battery when instrument doesn’t work.
