DCS system is a complete rack-mounted calibration station capable of
producing a flow of air
(or nitrogen) at a pre-specified range of dew-point temperatures
from a minimum of -100°C (-148°F) to a maximum of +20°C (+68°F).
Through customization the DCS system can be PC controlled for
automated calibration sequences or manually operated at pre-determined
When ordering this system, simply specify the required operating range, and Michell Instruments will determine the most economical way to construct your calibration system.
- Complete dew-point calibration solution with optional compressor, dryer, dew-point generator, reference instrument and optional manifold
- Generated output responds quickly to a change of set point
- Stable humidity generation
- Simple operation through manual flow mixing or push-button switching of set points
- Remote control via RS232 comms (dependant on model)

A source of very dry compressed air for use as a zero gas in humidity calibration systems, or for general laboratory applications.
A range of dew-point generators offering ease of use and fast response to humidity step changes.
Low-cost, transportable calibrator for dew-point and relative humidity sensors with built in chilled mirror reference.
Features an integrated sensor head allowing measurement in the range of -60°Cdp to +40°Cdp, combining the measurement sensitivity and ±0.1°C dew point accuracy of the RRS system.
Our flagship chilled mirror hygrometer, capable of measuring as low as -90°C dew point in a compact, lightweight package. The sensor head is optimised for fast response to low moisture levels and features the RRS system for high sensitivity and a dew-point accuracy of ±0.1°C.
Designed for very dry dew point measurements to -100°C (-148°F) with ±0.1°C accuracy. It features excellent stability and reproducibility across its entire measurement range, and is used in calibration and standards laboratories worldwide.
