Areas of application for the pyrometer optris CT G5

The pyrometer optris CT G5 covers a measuring wavelength suited for temperature measurements of glass. One important area of employment for the infrared measuring device is e.g. surveillance of the sterilization of glass bottles requiring sterility for pharmaceutical products.

Other areas of employment for the compact glass thermometer are flat-glass lines, container glass machines, lightbulb production and vehicle glass production. Additionally, the measuring device can be perfectly used for temperature control during the production of solar cells.

Infrared software optris Compact Connect included

The temperature analysis software optris Compact Connect has been developed specifically for the extensive documentation and analysis of temperature measurement data of our stationary infrared thermometers. It is license-free and included in every pyrometer shipment.
