Fluke 714B Temperature Calibrator

Fits field thermocouple calibration where you need to source/measure 17 TC types plus mV, and simultaneously measure an isolated mA loop — not a full multi-function documenting calibrator.

Key advantages

17 TC types + mV — source/measure thermocouples and −10…75 mV on one tool.
Isolated mA measure — simultaneous 0–24 mA channel; mA accuracy 0.010% + 2 µA.
IP52 handheld — 4× AA; magnetic hanger; dual backlit inputs.
Published TC tables — 1-year and 2-year TC accuracy tables in OEM documentation.

Typical applications

Field thermocouple calibration of transmitters and recorders.
Loop checks needing TC source plus isolated mA measure.
Companion use with RTD-focused 712B on the same cart.

Selection guide

Measuring / source range — 17 thermocouple types + mV (−10…75 mV); isolated mA measure 0–24 mA.
Accuracy — mA 0.010% + 2 µA; mV 0.015% + 10 µA (1-year, 18–28 °C); TC accuracies per OEM documentation tables. 1-year and 2-year specifications published.
Output / channels — TC / mV source; simultaneous mA measure channel. Dual inputs, backlit display.
Supply — 4× AA NEDA 1.5A IEC LR6.
Electrical connection — TC mini; banana for mA.
IP — IP52 (IEC 60529).
Ambient — Operating −10…+50 °C; storage −30…+60 °C; operating altitude 2000 m.
Mounting — Handheld; magnetic hanger included.
Weight / size — 515 g; 52.5 × 84 × 188.5 mm (H×W×L).
Approvals — IEC 61010-1; IEC 61326-1 Portable; MIL-T-28800E Class 2 vibration.

Common mistakes

Expecting RTD source/measure — 714B is thermocouple / mV focused with isolated mA measure; confirm RTD need against a different calibrator family.
Using 1-year accuracy figures outside 18–28 °C without checking the 2-year / extended ambient tables.
Assuming the mA channel sources loop current — datasheet lists isolated mA measure (0–24 mA), not mA source.
Ignoring IP52 limits in wet or dusty plant areas beyond that rating.
Ordering without confirming TC mini vs banana lead set for your sensor connectors.

When to RFQ / what to tell us

TC types you source/measure most often, and whether mV mode is required.
Whether simultaneous mA measure (0–24 mA) is needed on the same job.
Accuracy window (1-year vs 2-year) and ambient you calibrate in.
Lead/connector needs (TC mini, banana) and magnetic hanger use.
Quantity, ship-to country, and any documentation beyond the included traceable certificate.

FAQ

Q: Which sensors does 714B cover? A: 17 thermocouple types plus mV (−10…75 mV), with an isolated mA measure channel 0–24 mA. It is not positioned as an RTD calibrator in this OEM extract.

Q: What accuracy should I quote? A: mA 0.010% + 2 µA and mV 0.015% + 10 µA at 1-year, 18–28 °C; TC tables are in the datasheet. State which TC types and ambient you need.

Q: Is a calibration certificate included? A: OEM states a traceable certificate of calibration is included. Confirm any extra accreditation marks in the RFQ.

Q: What should I send for a quote? A: TC types, mA-measure need, accuracy window, quantity, ship-to. Compatible with workflows using Fluke 714B — we do not claim authorized-dealer status.
