Optris P20 05M Hand Held Infrared Thermometer


The Optris P20 are among the highest performance hand held infrared thermometers available. Their wide temperature and high optical resolution make them suitable for the most demanding of applications. All P20 thermometers include the innovative Optris dual laser aiming system which gives you both the location of the measuring and also its size at any distance. Also included is a scope for accurate aiming. Each model is packed with lots of useful features, and comes with a USB port making it very simple to connect to a PC and utilise the Optris Connect Report Software  that gives you graphical data in real time.

The Optris P20 05M is designed to measure the temperature of molten metals in castings applications. What makes it suitable is the sensitivity to very short wavelength infrared making it ideal in applications with very low emissivity such as this. With a wide measurement range of up to 1000 to 2000°C and excellent optical resolution of  300:1 giving you very small measuring spot sizes even at large distances. This allows the measurement of very high temperature at a safe distance which is not easily achieved by a traditional dip probe.

For solid metal and secondary metals processing please see P20 1M/2M. For lower temperature ranges please see P20 LT.
