Product overviewThe 7007, 6054 and 6055 deep-well baths provide immersion depth and thermal stability for precision temperature calibration. The 7007 is refrigerated, covers −5 °C to 110 °C, has a 24 in well and a removable polycarbonate cover. The 6054 covers 50 °C to 300 °C, has a 24 in well and a removable stainless steel cover. The 6055 is designed for 200 °C to 550 °C using molten salts, includes a pumping system to maintain fluid level for liquid-in-glass (LIG) thermometer calibrations and can be fitted with an optional stainless steel thermometer carousel (Model 2018). All wetted parts are 304 stainless steel and the series shares Fluke Calibration performance standards for stability and uniformity.
Key features- Extra-deep wells (17–24 in) for probes and LIG thermometers requiring deep immersion.
- Concentric-tube design for constant liquid level and repeatable conditions.
- Viewing channel and LIG sighting features (6055) to support glass thermometer alignment.
- Digital set-point and display with high-resolution options and repeatable temperature control.
Models- 6054 — Mid-range deep-well bath (50 °C to 300 °C), 24 in well, stainless steel cover.
- 6055 — Hi-temp deep-well bath (200 °C to 550 °C) using molten salts, 17 in well (configurations vary), optional Model 2018 thermometer carousel.
- 7007 — Refrigerated deep-well bath (−5 °C to 110 °C), 24 in well, removable polycarbonate cover.
