ETI RayTemp 38 Infrared Thermometer

The RayTemp 38 Infrared Thermometer from ETI is a professional IR thermometer with probe socket which features a dual laser dot alignment.  The infrared thermometer incorporates a 50:1 optic rati (target distance/diameter ratio) to allow users to measure small targets from a distance. 

The user must stand a safe and comfortable distance from their target and point the IR thermometer at the surface they wish to measure.  The temperature can instantly be read when the button is pressed.  The RayTemp 38 from ETI is ideal for measuring the temperature of ceiling vents and hot pipes in the HVAC industry, or any other item that is difficult to reach.  Using this instrument will allow most surfaces to be measured accurately and quickly.

An advantage of the infra red thermometer from ETI is the auto power off facility that turns the instrument off automatically after 60 seconds in order to maximise battery life (function can be disabled if required).  The clear, easy to read, backlit custom LCD display indicates both the temperature and the emissivity.  Different modes can be selected on the RayTemp 38 infrared thermometer through the four-button keypad, such as max, min, differential and average temperatures, view the max/min high and low alarms and adjust the emissivity from 0.1 to 1.0 in 0.01 increments (default set at 0.95).

An additional advantage is that IR thermometers are speedier and non-contact compared to conventional probe thermometers.  However, IR thermometers only measure the surface temperature.

There are some limitations of infrared thermometers.  This includes the inability to measure its internal (core) temperature.  An accurate measurement cannot be taken through any covering, including clingfilm, glass or polythene.  Surfaces which are being measured should be clean and dust free.  Air temperature cannot be measured with an IR thermometer which is another limitation.

This IR thermometer from ETI measures surface temperature over the range of -59.9 to 999.9°C with a 0.1°C (-9.9 to 199.9°C) or 1°C resolution.   Each RayTemp 38 is supplied in a protective ABS carrying case. 

Note: probe not included, must be purchased separately.
