What is a Supco tachometer used for?

The Supco tachometer measures rotational speed in rpm across HVAC equipment during maintenance and diagnostics. Field technicians use it for quick speed verification of motors, fans, and compressors without contact, supporting preventive maintenance workflows across Singapore's commercial cooling sector.

What are the specifications of the Supco tachometer COP14022?

Operating temperature range is -10 to 50°C with storage to -20 to 60°C. Measurement distance is 10–60 cm. It measures rotational speed in rpm and includes reflective marker, lanyard, and 3x AAA batteries for field deployment.

Where can I buy a Supco tachometer in Singapore?

3G Electric, an established industrial equipment distributor since 1990, supplies the Supco tachometer to Singapore. We handle all logistics, customs clearance, and delivery across the region, with lead times available on request.

How do I use a tachometer to check HVAC equipment speed?

Position the tachometer 10–60 cm from the equipment's rotating surface, aiming the sensor at the reflective marker placed on the spinning component. The display shows rpm in real time. Verify readings within the equipment's rated speed range to confirm normal operation.
