Automation Package 

Interface-it software and an RS-232 computer interface is included for setting the bath temperature via an external computer. For IEEE-488, add 2001-IEEE. 

Do you need a bath that chills below –40 °C to temperatures as low as –60 °C or even –100 °C? Would you like a bath that reaches those temperatures without using any external coolants? Hart has a variety of baths that meet these temperature requirements and give you the best stability in the industry. 

These baths are completely self-contained. They require no auxiliary cooling fluids or devices to achieve their set-point temperatures. Using Hart’s unique “heat-port” design, stability at –100 °C is ±0.0025 °C. No other company makes a bath that can match a Hart bath’s performance, and Hart baths are backed by our guarantee that if they don’t perform exactly the way we say they will, we’ll take them back. No arguments. No ifs, ands, or buts. 

Automate each of these baths with an interface package and Hart’s 9930 Interface-it software. If you want to completely automate the entire calibration process, see the description of Hart’s MET/TEMP II software package. 

Forget commodity-like utility baths! They’re not designed for high performance calibration needs. And be careful of companies that advertise performance specifications they don’t meet. It’s easy to write down numbers; it’s more difficult to meet them with an instrument. 

Remember, if our baths don’t perform the way we say they will, just send them back. Our equipment won’t disappoint you. 

Hart sells a complete selection of fluids for your bath. You can find these here.
