Pyrometer optris CT G5 for temperature measurement of glass

Due to its special spectral range of 5.0 µm, the pyrometer optris CT G5 is perfectly suited for the measurement of glass temperatures, e.g. during container glass production, vehicle glass production or solar cell production.

The IR thermometer’s stainless steel measuring head is extremely small and can be employed in ambient temperatures of up to 85 °C without additional cooling. A multi-installation of the pyrometers, e.g. in series as line scanner, is therefore cost-efficient and can be performed even in limited spaces.
