The Convir ST8839 Series is a
professional, low cost, handheld infrared thermometer with laser sighting and
large backlit LCD display.
Each unit measures from -50°C to 1000°C with 0.1°C resolution. They also offer an
outstanding 50:1 field of view, which helps to minimise errors by producing a small
diameter measurement area.
The emissivity setting is adjustable from 0.10 to 1.0 making the ST8839 suitable
for measuring most surfaces.

Readings can be taken in °C or °F, and when the trigger is released the last
measurement is held for 7 seconds before the unit automatically turns off.
This rugged unit will operate in ambient temperatures from 0°C to 50°C and is
powered by a standard PP3 9 V battery.
The ST8839 is supplied with a hard carrying case for added protection when
not in use.
