Fluke 724 Temperature Calibrator

Fits field temperature transmitter and sensor checks where you need one handheld tool that measures and sources thermocouples and RTDs, measures V/mA, and provides a 24 V loop supply with a dual measure/source display.

Key advantages

• Measure and source temperature — 10+ TC types and 7 RTD types plus V/mA/ohms on one handheld.
• 24 V loop supply — power two-wire transmitters during field checks (22 mA max, short-circuit protected).
• Published V/mA accuracy — typically 0.02% + 2 counts; RTD e.g. Pt100 (385) 0.33 °C (4-wire).
• Dual measure/source display — backlight UI with 25%/100% steps and auto step/ramp.

Typical applications

• Field calibration of temperature transmitters and sensors.
• Loop checks that need simultaneous measure and source with 24 V supply.
• Shop carts consolidating TC/RTD and V/mA tools into one calibrator.

Selection guide

• Measure / source ranges — V DC measure to 30 V / source to 10 V; mA 0–24 mA measure; resistance 0–3200 Ω; 10+ TC types + 7 RTD types measure/source.
• Accuracy — V/mA typically 0.02% + 2 counts; RTD e.g. PT-100 (385) 0.33 °C (4-wire); TC type-dependent (OEM tables).
• Outputs / loop — Source/simulate V, ohms, TC, RTD; 24 V loop supply (22 mA max, short-circuit protected).
• Supply — 4× AA alkaline (battery); typical life 25 h.
• Connections — Banana jacks; TC mini connector with internal CJC.
• Display — Dual measure/source display with backlight.
• Ambient / altitude — Operating −10…+55 °C; storage −40…+60 °C (OEM non-operating); operating altitude 3000 m max.
• Size / weight — 96 × 200 × 47 mm; 650 g.
• Features — 25%/100% steps; auto step/ramp. Three-year warranty per OEM published terms.
• Notes — Approvals field in JSON notes EMI-tolerant / field portable design per OEM documentation. No IP or hazardous-area rating published in the OEM extract used here. Certificates and standalone dimensional drawing were not harvested as public assets.

Common mistakes

• Ordering the 724 when you need documenting / HART communication — this SKU’s JSON does not list a communication bus; confirm against the OEM documentation if you need documenting.
• Assuming a single TC accuracy number — TC accuracy is type-dependent; use the OEM tables for the types you calibrate.
• Expecting an IP or Ex rating from this page — those fields are empty in our JSON.
• Ignoring battery life (~25 h typical) and spare AA cells for long field days.
• Mixing measure vs source voltage limits (measure to 30 V DC; source to 10 V).

When to RFQ / what to tell us

1. Sensor types you calibrate (TC types / RTD types) and whether 4-wire RTD is required.
2. Whether 24 V loop supply and mA measure are needed on the same tool.
3. Any documenting / HART need (confirm if this SKU fits or if another calibrator is required).
4. Quantity, accessories (test leads, cases), and ship-to country.

FAQ

Q: Which sensors can the 724 measure and source? A: 10+ thermocouple types and 7 RTD types, plus V, ohms, and mA measure ranges listed above. Confirm your exact TC/RTD types against the OEM documentation tables.

Q: Does it power a transmitter loop? A: Yes — 24 V loop supply, 22 mA max, short-circuit protected per the OEM extract.

Q: What accuracy should I quote for PT-100? A: Example published figure: PT-100 (385) 0.33 °C (4-wire). V/mA typically 0.02% + 2 counts; TC accuracy is type-dependent.

Q: What should I send for a quote? A: Sensor types, loop-power need, quantity, accessories, ship-to. Available for systems that use Fluke 724 — we do not claim authorized-dealer status.
