Bimetal Thermometer Afriso BiTh63 100 mm 0–120°C with G½ Connection

The Afriso BiTh63 bimetal thermometer with a 100 mm dial and a measuring range of 0–120°C is a mechanical temperature indicator intended for HVAC, heating and industrial applications. It uses a bimetal sensing element to convert temperature changes into a moving pointer on an analogue scale. The instrument features a G½ process connection for direct insertion into pipes, fittings or pockets and is suited to panel or surface mounting where a simple, reliable temperature readout is required.

Advantages

The bimetal sensing mechanism provides maintenance-free temperature measurement without the need for external power. The 100 mm dial offers improved readability for quick visual checks. The G½ connection allows straightforward installation into standard threaded ports commonly found in heating and process systems. The robust construction ensures stable indication under typical HVAC and industrial operating conditions.

Suitable for

• Temperature monitoring in heating systems and boilers
• HVAC distribution and air handling units
• Pipes and process lines where direct insertion measurement is required
• Panel mounting for local temperature indication

Key specifications

• Dial diameter: 100 mm
• Measuring range: 0–120°C
• Sensing element: bimetal coil
• Process connection: G½ threaded connection
• Display: analogue pointer with graduated scale
• Mounting options: direct insertion into threaded port or panel/pipe mounting

How to use

Install the thermometer by threading the G½ connection into a compatible port, pocket or tee on the pipe or vessel. Ensure the sensing element is in good thermal contact with the medium being measured and that any sealing material used is suitable for the operating temperature. For panel mounting, use the appropriate mounting bracket or recess and secure the instrument so that the dial remains visible for reading. After installation, allow the instrument to stabilise and verify the indicated temperature against a reference if required.

Usage recommendations

For accurate readings, avoid placing the thermometer in locations with strong vibrations or rapid air drafts that could affect the bimetal element. Use the thermometer within its specified temperature range and select an appropriate insertion depth or pocket to ensure representative measurement of the medium. Regular visual inspection is recommended to confirm the dial and connection integrity.
