Fluke 7103 | Low-Temperature Portable Micro-Bath -30°C to 125°C

Below-ambient temperature calibration can be difficult when sensors are short, oddly shaped or unsuitable for conventional dry-well inserts. The Fluke Calibration 7103 Micro-Bath provides liquid-bath flexibility in a compact portable system operating from -30°C to 125°C.

The Micro-Bath design supports stability to approximately ±0.03°C and uniformity to ±0.02°C. Its 48 mm × 140 mm tank accepts sensors with shapes or lengths that are difficult to accommodate in dry blocks. Compressor-free cooling contributes to portability and reduces mechanical complexity, while the spill-resistant lid assists transport with calibration fluid. RS-232 connectivity, eight stored set points and thermal-switch contacts support structured calibration procedures in both laboratory and field environments.

Low-Temperature Micro-Bath Selection Guide

Choose the 7103 when a liquid calibration environment is required from -30°C to 125°C. The 6102 is intended for above-ambient work up to 200°C.

Market Relevance

The Fluke 7103 is relevant to Pakistan's cold-chain, pharmaceutical, food, refrigeration, laboratory and temperature-validation sectors. Buy the Fluke 7103 from Kamadi Pakistan for portable below-ambient liquid-bath calibration.

Key Features

• Temperature range down to -30°C
• Compact portable liquid bath
• Stability to ±0.03°C
• Uniformity to ±0.02°C
• RS-232 and thermal-switch contacts

Technical Specifications

• Model: Fluke 7103
• Temperature Range: -30°C to 125°C
• Stability: ±0.03°C
• Uniformity: ±0.02°C
• Tank Diameter: 48 mm
• Tank Depth: 140 mm
