Key features
- Stability and uniformity better than ±0.008°C, perfect for precision thermometer testing.
- Can be used on benchtops or on matching carts
- Available in high-temperature (150 °C) and low-temperature (-80 °C) models.
- Excellent temperature stability (±0.005 °C) and uniformity (±0.005 °C).

7340
With an optional floor cart (including locking casters), your bath can easily be moved to any place you need it. (Available for the 7340). Casters included on the 7380.
Also featuring large work areas, our Model 7340 baths cover your needs for low temperature calibrations. The 7340 reaches cold temperatures to –40 °C. Below 0 °C, these baths maintain an impressive stability of ±0.005 °C with uniformities better than ±0.006 °C. No utility bath performs as well as Fluke Calibration’s compact baths below 0 °C or at critical room and body temperatures—or even at important higher temperatures such as 100 °C and 122 °C.
7380
For ultracold temperatures, the 7380 reaches –80 °C quickly and maintains a two-sigma stability of ±0.006 °C when it gets there. The 7380 is a true metrology bath, not a chiller or circulator. With uniformity to ±0.008 °C, comparison calibration of temperature devices can be performed with high precision.
Each bath includes an RS-232 serial interface and our Model 9930 Interface-it software for controlling your bath from a PC. With a Fluke Calibration thermometer readout, such as a Black Stack, and our MET/TEMP II software, automated calibrations can run unattended.
Fluke Calibration doesn’t make chillers, circulators, or so-called utility baths, and utility bath manufacturers don’t make metrology baths. Use the right tools for your work and reap the best possible results. Baths from Fluke Calibration are the most stable and uniform of any you’ll find. They’ll give you results no other bath can.
