Optris CSlaser G5HF Infrared Pyrometer

The CSlaser series of sensors are the lowest cost in our range of infrared pyrometers with the innovative dual laser aiming system which gives the user both the position of the measurement and also its size as the lasers are factory configured to match the optics of the sensor. The sensor and electronics are housed in one convenient housing and connected to your instrumentation by standard cable. Emissivity is adjusted easily via two switches in the back of sensor accessed by four screws.
The CSlaser G5HF, operating in the 5µm part of the infrared spectrum, this sensor has been designed specifically for accurate temperature measurement of glass surfaces during manufacture and processing. A selection of optics allow measuring spot sizes to be as small as 1.6mm with the CF1 selection or alternatively the SF optics with an optical resolution of 45:1 give moderate spot sizes at further distances. The sensor has a wide measuring range of 200 to +1450°C and an industry standard 4-20mA output. It is also easy to connect our innovative USB interface which allows simple configuration and on screen measurement with the included Compact Connect Windows software.

Take a look at what makes the CSlaser LT such a great infrared pyrometer.

Calibration as well as a full range of accessories are available for the Optris High Performance infrared pyrometers.
