These portable dry wells are the smallest, lightest, and most portable dry-wells in the industry.
Despite its small size (2 1/2 inches high and 5 inches wide) and lightweight, the 9100S outperforms all other dry-wells in its class. Anyone can learn to use one in less than 15 minutes. It has a range to 375°C (707°F) and is perfect for checking RTDs, thermocouples, and small bimetal thermometers in the field.
Plug it in, switch it on, set the temperature with the front-panel buttons, and insert your probe into the properly sized well. Benefiting from a proprietary Hart Scientific temperature controller, the HR910021 has a display resolution of 0.1 degrees, an accuracy of ±0.5°C, a stability of ±0.1°C, and a stabilization time of just five minutes.
The HR9102S is excellent for dial gauges, digital thermometers, bulb switches, and other sensors that need calibration below ambient. For work in the temperature range of -10°C to 122°C, the HR9102S dry-well is the industry’s choice, featuring stability to ±0.05°C. This dry-well is only four inches high and six inches wide, achieves temperatures as low as -10°C. The HR9102 has two wells so you can use one for a reference thermometer to increase accuracy. Both wells are 1/2 inch in diameter, and each has inserts available for almost any sensor size. The HR9102S also has a battery pack option that gives you approximately four hours of field use when AC power is unavailable.
