Fieldpiece TC24 Pipe Clamp Type K Thermocouple | 3/8" to 1-3/8"

Fieldpiece TC24 Pipe Clamp Type K Thermocouple — Fast Pipe Temperature Readings for HVAC/R

The Fieldpiece TC24 is a pipe clamp style Type K thermocouple designed for fast, accurate pipe temperature measurement on residential and light commercial HVAC/R systems. The sensor clamps directly onto the pipe surface — no tape, no putty, no waiting — and delivers a stable reading in under 30 seconds. It suits pipe diameters from 3/8" to 1-3/8" outside diameter, covering most common suction and liquid line sizes in residential and light commercial cooling systems.

The TC24 connects to any thermometer with a Type K thermocouple mini jack — it is not a wireless probe. If you need wireless pipe temperature measurement for the Fieldpiece Job Link system, see the Fieldpiece JL3PC wireless pipe clamp.

TC24 vs JL3PC — Wired vs Wireless

• TC24 ($154.95): Wired Type K thermocouple. Connects to any compatible thermometer via mini plug. No batteries, no app required. Simple and reliable for everyday pipe temperature measurement.
• JL3PC ($250.95): Wireless Bluetooth pipe clamp for the Fieldpiece Job Link system. Connects to the Job Link app for remote monitoring, data logging, and report generation. Suited to technicians using the Job Link wireless diagnostic ecosystem.

Best For

• HVAC/R technicians measuring suction line and liquid line temperatures for superheat and subcooling calculations
• Residential and light commercial AC service and maintenance
• Technicians who need a simple, reliable wired pipe temperature probe
• Use with Fieldpiece meters and any thermometer with a Type K mini jack

Check Before Ordering

• Confirm pipe outside diameter is within 3/8" to 1-3/8" range
• Confirm your thermometer has a Type K thermocouple mini jack input
• The TC24 is a wired probe — for wireless Job Link connectivity, see the JL3PC
• Maximum continuous use temperature is 257°F (125°C) — confirm suitability for your application
• Confirm warranty terms with HVAC Trade Supply at time of purchase

Frequently Asked Questions

What pipe sizes does the TC24 fit?

The TC24 fits pipe outside diameters from 3/8" to 1-3/8". This covers most suction and liquid line sizes in residential and light commercial cooling systems. Confirm your pipe OD before ordering.

What thermometers is the TC24 compatible with?

The TC24 connects to any thermometer with a Type K thermocouple male mini jack input. Confirm compatibility with your specific meter before ordering.

How accurate is the TC24?

Standard accuracy is ±4°F (±2°C). After field calibration, accuracy improves to ±1°F (±0.5°C) in the 32°F to 176°F range — meeting California Title 24 specifications.
