Hart’s line of portable dry-wells is incredible. They’re the smallest, lightest, and most portable dry-wells in the world. And now they're better than ever!
Since we introduced the world’s first truly handheld dry-well, many have tried to duplicate it—in vain. Despite its small size (57mm x 125mm x 150mm) and light weight, the 9100S outperforms every dry-well in its class in the world.
It’s simple and convenient, too. Anyone can learn to use one in less than 15 minutes. It has a range to 375°C 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. Compare the reading of your device to the display temperature or to an external reference, and the difference is the error in your device. With a proprietary Hart Scientific temperature controller, the 9100S 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.
