Benchtop Calibration Baths from Hart Scientific

If you’ve already heard Hart Scientific makes the best-performing calibration baths in the industry, did you also know that we make baths for virtually any application, temperature range or budget? Hart’s line of great baths start with our three benchtop models.

Like our larger floor-model baths, these units feature great stability and uniformity. All three baths are stable and uniform to ±0.005°C. Other companies promise high stability but deliver only ±0.02°C, which is not adequate for temperature calibration work. The companies that make them almost never provide bath stability figures across the bath’s entire operating range. If they did, you wouldn’t buy the bath.

Each of these benchtop units uses Hart’s own proprietary controller technology to achieve cutting-edge control. They have large stainless steel tanks with large openings for holding several probes at a time, and each has an optional RS-232 or IEEE interface package with a 9930 Interface-it software package.

If you don’t want to control your bath with your PC, set-points can be manually set through the front panel. Eight of your most frequently used settings are stored in memory for faster setup. Lexan and stainless steel covers are also available.

These are not mass-produced utility baths. They’re true calibration baths made to meet the demanding needs of calibration labs. Each bath is tested for stability before it’s shipped, and we measure the operating specs in the bath fluid itself, not in an isothermal block to make our numbers look better. No one knows baths the way Hart Scientific does, and no one delivers a better product than Hart. No one!

This benchtop bath takes up just a bit more than one square foot of counter space and weighs less than 26 pounds, yet it achieves stability of ±0.005°C at 100°C and ±0.007°C at 200°C. Uniformity is ±0.007°C at any temperature and anywhere in the tank.

The Model 6025 bath is inexpensive enough to use as a dedicated bath at a fixed temperature. It’s designed to last for years and comes with an unbeatable industry-leading two-year warranty.

The controller is digital, so you can electronically set bath operating temperatures and safety cutouts. There’s an optional interface package for complete computer automation. (Back to Specifications)

If you need a higher temperature range but want the same stability, uniformity and size as found in the Model 6025, Hart has the Model 6035 Benchtop Calibration Bath.

This unit weighs less than 35 pounds with the same footprint as the 6025. The well opening is 18 square inches and the tank is 9.5 inches deep.

Bath stability is ±0.005°C at 100°C and ±0.015°C at 300°C. The set-point resolution is 0.01°C. The tank holds just 2.1 gallons of fluid, so the cost of supplies is low.

If you’re doing work below ambient, this is the benchtop model for you, and like all Hart baths, it leads the industry in performance.

It has stability of ±0.005°C at 100°C and ±0.01°C at –20°C and uses only 2.1 gallons of fluid, so you can move the temperature up and down quickly between temperature changes.

Uniformity is an outstanding ±0.005°C throughout the tank, so you can calibrate or check more than one probe at a time.

Don’t forget: you can do fully automated calibrations with all three of these benchtop units by using the optional Hart 9932 Calibrate-it software package and RS-232 interface. (Back to Specifications)
