The ST642 is a low-cost, high-quality handheld infrared thermometer with laser sighting and a large backlit LCD display.
A wide temperature range covers most general industrial applications. The unit offers a narrow 12:1 field of view, with a small diameter measurement area, thus allowing the unit to have a precise aim. The default emissivity setting is 0.95, making the ST642 ideal for most organic materials and non-reflective (painted, oxidised or anodised) metals.
The emissivity setting is adjustable from 0.1 to 1.0 and can be set automatically by using the thermocouple input and eSmart feature. This model has adjustable audible alarms, and also has visual alarms: the colour of the display changes when the target temperature exceeds the alarm set point. Readings can be taken in °C or °F and when the trigger is released, the last measurement is held for approximately 7 seconds before the unit automatically powers off.This thermometer will operate in ambient temperatures from 0°C to 50°C and is powered by a standard PP3, 9V battery. Each unit is supplied with a soft carrying case.
