You’ll find more Hart baths in national calibration labs than any other brand, and there’s a reason for that. No one else can match the stability, uniformity, and performance of a Hart bath, and we absolutely guarantee it.
These three models are designed for high-temperature work up to 550°C. Most labs use them as salt baths for calibration of thermocouples, RTDs, and SPRTs. In fact, these baths are so good you can even do comparison calibrations of SPRTs with them. These baths are stable to ±0.005°C or better at 300°C.
Each bath has a drain, built-in cooling coils, electronically adjustable temperature cutouts, optional floor carts, and optional automation software and interface packages. (The 6050 and 6050H come with an insulated cover.)
Hart is the only company that offers complete automated calibration software packages that work with the bath interface option. Our optional software is not just a data acquisition package; it actually controls the calibration, including bath temperatures.
Choose the model that most closely matches your needs. These baths are compatible with salt for higher temperatures and also with oils for lower temperatures.
Model 6045
This bath has a temperature range of 40°C to 400°C and is perfect for thermocouples and RTDs.
It has a large well opening (5 by 10 inches) so you can calibrate a number of sensors at once. It’s 12 inches deep and uses 25 liters of fluid.
The automation interface package gives you complete PC control of the bath, including precalibration setup. It’s available with an RS-232 interface or IEEE-488 interface.
Model 6050
The Hart Model 6050 goes to 500°C and is 10 to 100 times more stable than alternative calibration devices.
It, too, is 12 inches deep and has a 5- by-10-inch well opening for easy access. Ports in the rear of the bath access cooling coils if you want to cool the bath rapidly with external fluids.
