It’s no secret why Hart’s temperature baths are the most stable baths in the world. In fact, right on page 96 of this catalog we explain that Hart baths use Hart temperature controllers, and they’re flat out the best anywhere. 

If you’re using a homemade bath—or worse, a bath built by one of our competitors—there’s a good chance you can drastically improve its performance by using one of Hart’s two temperature controllers. 

The 2100 controller can sense and respond to temperature changes as low as 0.00001 °C, which means you can enjoy stabilities better than ±0.001 °C in a mechanically sound bath. 

The 2100 has set-point resolution of 0.002 °C using a thermistor input and 0.01 °C using an RTD input. In high-resolution mode you can adjust the set-point in increments smaller than 0.0002 °C. Actual display resolution is 0.01 °C. 

Power output is provided on a standard IEC female power receptacle. An auxiliary power output provides constant line voltage to equipment accessories such as stirrers. 

The 2200 controller is smaller and lighter than the 2100 and uses an RTD input to provide stabilities as good as ±0.015 °C. Resolution is 0.01 °C and temperature range is –100 °C to 800 °C. 

If operated from any line power between 100 and 230 VAC, 50 or 60 Hz, the 2200 will supply up to 10 amps power output on a standard IEC female power receptacle. 

Both models are programmed using the front-panel buttons and also come with an RS-232 interface. 

Either of these benchtop controllers can turn an average temperature bath into a true calibration tool. Call us and tell us your application. We’ll help you pick the best controller for your situation.
