Handheld infrared thermometer with adjustable emissivity setting and Type K thermocouple input. with LCD. 5~14um spectral range. -32~535°C temperature range. Emissivity Setting Adjustable 0.1 to 1.0 and audible alarm. The ST640 Series is a range of low cost, handheld infrared thermometers with laser sighting and large backlit LCD displays.Each unit measures from -32°C to 535°C with 0.1°C resolution. They also offer a superior 12:1 field of view, which helps to minimise errors by producing a small diameter measurement area.The emissivity setting on the ST640 is fixed at 0.95, making it ideal for most organic materials and non-reflective (painted, oxidised or anodised) metals. The emissivity setting on the ST642 is adjustable from 0.1 to 1.0 and can be set automatically by using the thermocouple input and eSmart feature.Both models provide adjustable audible and visual alarms in which 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 turns off.ST640 series thermometers will operate in ambient temperatures from 0°C to 50°C and are powered by a standard PP3, 9V battery.Each unit is supplied with a soft carrying case.
