Product Code: HL-1850D

The HL-1850D infrared laser thermometer is very robust and well suited to applications where contact measurement is not possible or desirable. A Type K Thermocouple can be connected via a miniature plug.

The HL-1850D is very easy to use: simply point and measure. The measurement is read within 1 second and the dual laser targetting helps to precisely identify your measurement point. The unit has an an adjustable emissivity, 50:1 spot to distance ratio and includes a data loggin function for up to 99 readings (software and USB cable supplied).

As standard the HL-1850D features a High / Low alarm facility, as well as Min/Max, Average and Difference functions. The temperature readouts are backlit making them easy to read, even in the dark. A wide range of hand-held thermocouples are also available.
