Regardless of the size and number of standard resistors you have to maintain, Hart has a bath that will do the job for you. Choose one of the three models described here or call us for information on other sizes.

Like all Hart baths, these resistor baths have unbeatable stability and uniformity. (See Buying the Right Bath and Why a Hart Bath?) No other baths limit long-term and short-term drift—as well as gradients—better than these baths. Hart’s proprietary controller senses temperature changes as small as 0.00001°C. This controller is the industry’s best-selling temperature calibration controller for bath retrofits because it improves the stability of almost every other poorly performing bath. So why not buy the best to begin with?

Each bath can be delivered with any size resistor rack you want (a standard model is included with each bath), and the Model 7015 has several other special features that make your work easier. A new independent high- and low-temperature cutout provides maximum protection for your standard resistors and their calibration history.

Model 7015
The Model 7015 has a 95-liter tank and a temperature range of 0°C to 110°C. It’s stable to ±0.0007°C.

It has a one-piece stainless steel lid designed to drain spills and splashes back into the bath as you remove resistors. It has a large access opening to make handling large resistors, like the Thomas Design Standard resistors, easier. The tank has an electrically isolated resistor shelf.

This is truly a quality resistor bath, and it’s backed by Hart’s industry-leading service.
