Bimetal Thermometer Afriso BiTh 80 (model 63806) — bimetal sensor, dial 80 mm

The Afriso BiTh 80 bimetal thermometer (model 63806) is an analog temperature indicator with an 80 mm diameter dial and a bimetallic sensing element. It provides direct local temperature readings for HVAC, heating systems and simple industrial monitoring. The instrument is designed for straightforward installation on panels, pipes or surfaces when used with appropriate mounting accessories, offering a reliable visual reference for process monitoring and basic control tasks.

Advantages

The bimetal sensor delivers stable mechanical response without the need for electrical power, ensuring continuous temperature indication. The 80 mm dial offers clear legibility at typical viewing distances, and the analog pointer enables immediate recognition of temperature trends. Compact construction and robust materials provide durability in building services and light industrial environments, while compatibility with common mounting options supports flexible installation and retrofitting.

Suitable for

• Temperature monitoring in HVAC systems and boilers
• Pipe and surface temperature indication in heating networks
• Local temperature display for industrial machines and equipment
• Panel mounting for electrical and control cabinets

Key specifications

• Sensor type: bimetallic sensing element
• Dial diameter: 80 mm
• Display: analog pointer on graduated scale
• Mounting options: panel, pipe or surface (dependent on accessory)
• Application environment: HVAC, heating systems, light industrial use

How to use

Select the appropriate mounting accessory for panel, pipe or surface installation and ensure the sensing element is in direct thermal contact with the measurement point. Mount the instrument securely to avoid vibration and mechanical stress that could affect reading accuracy. Read the temperature from the analog pointer on the 80 mm dial; allow sufficient time for the bimetal element to reach equilibrium after a rapid temperature change. Periodic visual inspection and basic checks ensure continued reliable operation.

Usage recommendations

To maintain reading accuracy, avoid installing the thermometer in locations subject to strong drafts, direct radiant heat or rapid temperature cycling. If a sealed or remote measurement is required, choose an appropriate probe or thermowell accessory and follow installation guidelines specific to the mounting option.
