Have you been thinking about buying a zero-point dry-well? Forget those ugly-looking units the competition makes. You can get a great looking and great performing zero-point dry-well from Hart Scientific. 

The Hart 9101 has three test wells for inserting more than one probe at a time. All three wells are stable to ±0.005 °C. One well accommodates changeable inserts for varying probe diameters. 

The Model 9101 takes advantage of the latest solid-state cooling technology rather than relying on older, less reliable sealed-water-cell devices. This eliminates the possibility that the sealed water cell will freeze and burst while transporting the unit to field locations. And our solid-state cooler is run by an adjustable electronic controller that can be recalibrated in your lab for convenient recertification. Simply place a certified standards thermometer in one of the wells and, if needed, tweak the 9101 controller until the standards thermometer reaches equilibrium at 0 °C. 

Since the unit is completely self-contained and doesn’t require any user settings, you can run it on demand for instant access to an accurate, traceable zero point. Set it up with the reference junction of a thermocouple for high-accuracy thermocouple measurements. 

Less costly than refrigerated baths, more accurate and less problematic than ice baths, and more durable and better looking than competitive units using sealed-water cells, the Hart 9101 Zero-Point Dry-Well is a great choice for any calibration lab!
