Greisinger GOF 900 HO Surface Temperature Probe Pt1000 -65 to +900°C 117220

The GOF 900 HO stands out among surface probes with its spring-loaded silver lamella tip, which follows flat or slightly curved surfaces for fast, repeatable measurements. A Pt1000 sensor in 2-wire configuration covers -65 to +900 °C with short-term excursions to +1000 °C, making it suitable for demanding industrial and laboratory tasks.

Highlights

• Spring-loaded silver lamella tip (15 mm diameter) for optimal surface contact
• Wide measurement range: -65 to +900 °C, short-term up to +1000 °C
• Pt1000 sensor, Class B accuracy (±0.3 °C at 0 °C)
• Fast response: t90 approx. 3 seconds on metal
• Robust stainless steel shaft (8 mm diameter, 130 mm length)
• 1 m cable with 3.5 mm stereo jack plug

In daily use

The TPE handle and cable withstand up to +100 °C, allowing the probe to be used near hot surfaces without damage. The 2-wire Pt1000 element provides reliable resistance-thermometer measurements when connected to compatible Greisinger instruments or other devices with a 3.5 mm jack input.
