Bimetallic Surface Thermometer Afriso ATh 63F, 63 mm dial, model 63822

Afriso ATh 63F is a bimetallic surface (clip-on) thermometer with a 63 mm dial, model 63822. It provides direct local temperature indication for pipes and flat surfaces using a bimetallic sensing element. The instrument is intended for quick mechanical readings without external power, making it suitable for HVAC systems, industrial piping and general plant maintenance where stable, easy-to-read temperature display is needed.

Advantages

The bimetallic sensing mechanism delivers reliable, maintenance-free temperature readings and does not require electrical power. The compact 63 mm dial offers clear visibility in confined spaces and on building services equipment. Its clip-on design enables simple attachment to pipes or flat surfaces, allowing fast installation and removal for spot checks. The robust construction is designed for repeated use in service and maintenance tasks.

Suitable for

• Temperature checks on heating, ventilation and air conditioning (HVAC) pipework
• Monitoring industrial process and service pipelines
• Routine maintenance and plant inspection tasks
• Spot measurements on flat surfaces and equipment housings

Key specifications

• Dial diameter: 63 mm for compact mounting and good legibility
• Sensing element: bimetallic coil for direct mechanical temperature indication
• Mounting type: clip-on design for attachment to pipes or flat surfaces
• Display: analog pointer on graduated dial for immediate reading
• Construction: durable housing suitable for service and maintenance environments

How to use

Attach the thermometer clip to the pipe or place it securely on the flat surface so that the sensing element has good thermal contact with the measured medium. Ensure the instrument is aligned so the dial is visible for reading. Allow sufficient time for the bimetallic element to reach thermal equilibrium with the surface before taking a reading. For repeat checks, remove and re-clip as required; no calibration power source is necessary for normal operation.

Usage recommendations

For most accurate surface readings, clean the contact area and, where appropriate, use thermal paste or pad to improve thermal coupling between the surface and the sensing element. Avoid exposing the instrument to temperatures beyond its specified operating range and protect it from mechanical shocks. Regular visual inspection will help maintain reliable readings during routine maintenance and inspection work.
