7103 Overview

The Fluke Calibration 7103 Micro-Bath is a portable instrument/bench-top temperature calibrator. Used for calibrating thermocouple and RTD temperature probes, it is small enough to use in the field, and accurate enough to use in the lab. With an ambient temperature of 23 Celsius (74 F), calibrate over a range of −30 C to 125 Celsius (-22 F to 257 F). The resolution of the display is 0.01 degrees.

It's lighter and smaller than most dry-wells, has a spill-proof lid, and is easier to carry than your lunch. You can take it where you need to go without carts or excessive effort. Micro-Baths can even be transported with the fluid in them.

Wherever you go with your Micro-Bath, you can count on its performance. You get the stability and precision of a liquid bath in a dry-well-sized package. Don’t be fooled by competitors who pour oil into a dry-well and call it a bath. Micro-Baths are maximized for true fluid-bath performance.

With a 48 mm (1.9-inch) diameter, 140 mm (5.5-inch) deep tank, a Micro-Bath can calibrate any type of sensor including short, square, or odd-shaped sensors. The problems of fit and immersion are virtually eliminated by using a fluid medium rather than a dry-block calibrator. Micro-Baths are perfect for liquid-in-glass and bimetal thermometers.

Cold Micro-Baths are CFC-free, and also compressor-free. That's right—no heavy, noisy compressor to lug around. Fluke achieves its temperature range and stability with only one moving part. This means more durability and less weight. Fluke Calibration manufactures and sells temperature calibration baths of every size and shape, and now Fluke has the smallest and lightest baths in the industry to go with the dozens of other models they make.
