Bimetal exhaust gas thermometer Afriso RT 80, Ø80 mm, length 150 mm, 0–300°C, axial, class 2

Afriso RT 80 is a bimetal exhaust gas thermometer for direct, mechanical indication of flue and exhaust gas temperatures. The instrument has an 80 mm diameter dial, a rigid stainless steel probe 150 mm long and an axial connection. The measurement range covers 0–300°C with accuracy class 2, making it suitable for visual monitoring of combustion systems where a simple, robust temperature indicator is required.

Advantages

The bimetal sensing element provides reliable, maintenance-free readings without electrical supply. Its axial mounting and compact Ø80 mm dial allow installation in tight boiler rooms and on burners. The stainless steel probe ensures resistance to typical exhaust gas environments, and the clear graduated dial supports quick checks by technical staff. The mechanical design reduces vulnerability to electrical interference and offers long-term stability under normal operating conditions.

Suitable for

• Monitoring boiler exhaust gas temperature
• Checking furnace and kiln flue gas temperatures
• Industrial burner temperature supervision
• Field service checks and mechanical control panels

Key specifications

• Measuring principle: bimetal thermometer
• Dial diameter: 80 mm
• Probe length: 150 mm (rigid)
• Connection orientation: axial
• Measuring range: 0 to 300 °C
• Accuracy class: 2
• Display: analog pointer on graduated dial
• Probe material: stainless steel (suitable for exhaust gas use)

How to use

Install the thermometer in an axial port of the exhaust or flue system so that the probe extends into the gas stream to the required insertion depth. Tighten the connection securely to prevent gas leaks and ensure the dial is visible to operators. Observe the pointer position on the graduated dial to monitor temperature; no electrical connection is required. For best results, install at a representative location of the flue where flow conditions and stratification are minimal.

Usage recommendations

When using the Afriso RT 80, avoid mounting the probe in locations with excessive soot buildup, strong condensate formation or direct flame contact. Regular visual inspection of the probe and dial for soiling or damage will help maintain readability and reliable operation. For systems with pulsating flow or aggressive exhaust components, consider protective sleeves or appropriate maintenance intervals.
