Fluke 3103-3 Insert "B" with comparison holes for 9103 and 9011
What is the Fluke 3103-3 Insert “B” Calibration Insert?
The Fluke 3103-3 Insert “B” is a precision temperature calibration insert designed for UK calibration technicians and electrical engineers using Fluke dry-well calibrators. It allows accurate and repeatable probe positioning when calibrating temperature sensors in the Fluke 9103 Field Dry-Well and compatible models.
With multiple comparison hole sizes, this insert supports a range of probe diameters, helping improve thermal contact and measurement stability during field or laboratory calibration work.
How does the 3103-3 stand out in everyday calibration work?
The insert’s comparison-hole design allows technicians to calibrate multiple probes with consistent heat transfer, reducing errors caused by poor probe fit. It’s ideal for engineers working in electrical maintenance, process control and calibration services who need dependable results that support compliance and traceability.
Designed as a removable insert, it also makes it easy to expand probe compatibility or replace worn inserts without replacing the entire dry-well system.
