The Mensor CTD4000 Dry Well Calibrator has been designed for on-site applications as well as for the severe conditions of the naval and marine sectors. Its ease of use, compact and practical design make it unbeatable in industrial processes where calibration of temperature measurement systems is essential for process control and product quality.

Special attention is paid to reduce weight, size and to reinforce robustness by using an aluminum body as well as aluminum and stainless steel for many internal parts. The calibrator operates over a temperature range of -24°C to 140°C with accuracy of 0.25K at 100°C and stability of ±0.1K. With the available standard inserts, the calibrator is versatile and can be easily adapted for calibration of temperature probes with the most common diameters. It also includes the capability to check temperature switches.
