Infrared Thermometer UNI-T UT309A PRO The professional non-contact infrared
thermometer UT309A can quickly and accurately determine the surface temperature
in the range of -35°C to +450°C by measuring the infrared energy radiated from
the target surface. The UT309A is a very durable device suitable for everyday
use. It is resistant to falling from 3m and the excellent degree of protection
IP65 ensures good resistance to water and dust. The UT309A has a fixed
emissivity of 0.95 and one aiming laser, which indicates the correct aiming of
the thermometer. The ratio of the distance to the diameter of the measured
surface is 10: 1 with this instrument. The indication of preset functions and
measured temperature values ?is provided by a high-contrast LCD black-and-white
display, and exceeding the temperature limit values ?is indicated by LED diodes
(exceeding the upper limit red and the lower limit blue). It is possible to set
a continuous measurement, when after 2 minutes the backlight of the display
turns off, after the end of the measurement by pressing the shutter button
again, the temperature value remains on the display. The temperature measurement
time is up to 250msec in 95% of cases. It is possible to indicate the minimum,
maximum and average temperatures and the difference between the highest and
lowest measured temperature (MIN, MAX, AVG, DIF). The thermometer switches off
automatically, in order to reduce consumption, if it is not used for 8 s. This
switch-off can be switched off. Product parameters : - infrared thermometer for
non-contact measurement of surface temperatures - temperature range -35°C to
