The 3000 Series dry-wells allow users to check the accuracy of thermometers and sensors as a system on site, without the need for heavy, expensive equipment. The dry-wells are high accuracy portable heat sources which are extremely easy to use. Simply plug in, switch on and set the dry-well to the temperature that you wish to check, insert your probe into the correct size well and take the reading. Compare the temperature reading of your thermometer and probe to the displayed temperature of the dry-well and the difference is the error of your instrument.

The 3000 Series dry-wells features a bright, easy to read, LED display with a temperature range of +33 to +300°C, a resolution of 0.1°C with an accuracy of ±0.5°C over the range of +33 to +199°C and ±1°C accuracy over the range of +200 to +300°C. Should you need to change the temperatures of the heat source, the small, fan cooled aluminium block heats and cools rapidly, so it will not keep you waiting. These units are ideal for use in a variety of industrial and process applications. The 3000 Series dry-wells are powered by 230 volts AC.

Each unit is supplied with a traceable certificate of calibration showing actual test data, which can be used as part of quality assurance programmes. The units measure 57 x 125 x 158mm and weigh 900 grams. Each dry-well is supplied complete with a 5-point traceable certificate of calibration with data at the following points: +50°C, +100°C, +150°C, +200°C and +250°C.

3101 Dry-Well
The 3101 Dry-Well features an easy to read LED display with a temperature range of -10 to +110°C, a resolution of 0.1°C with an accuracy of ±0.5°C over the range of -10 to +99°C. Stability is ±0.2°C. Heating time to +100°C is 10 minutes, cooling time taken from ambient to 0°C is 10 minutes.

The 3101 is excellent for checking the calibration of a wide range of instrumentation including digital thermometers, bi-metal dial thermometers and thermosensors that need calibration checks below ambient. The unit has two wells, both wells are 13mm in diameter and will accept removable inserts for monst sensor diameter sizes as follows: 3.3, 4.1, 4.8, 6.4 and 9.6mm. The 3101 is supplied with two inserts, 4.76 and 6.35mm.
