Compact baths with the stability and uniformity required for precision thermometer testing
- Stability and uniformity each better than ±0.008°C
- Metrology-level performance in lab-friendly sizes
- Convenient use on benchtops or on matching carts
Find a high temperature bath (300 °C) or refrigerated calibration bath for low temperature calibration (i.e. –80 °C), in compact packages from Fluke Calibration. Fluke Calibration metrology baths are well known world-wide for excellent temperature control that maintains excellent temperature stability (±0.005 °C) and uniformity (±0.005 °C).
When you only need a circulator or utility bath to control a process within a few degrees or to maintain biological test samples, talk to a utility bath manufacturer. But when you’re doing precision thermometer testing, and stability and uniformity are critical to the success of your work, talk to us.
Fluke Calibration has been making the world’s best-performing temperature baths for almost two decades. With our proven heating/cooling designs and hybrid analog-digital controller, Fluke Calibration baths apply the most effective technologies that are commercially feasible. These four compact baths are no exception.
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.
