Calibration Equipment for Process Analytics

The ADG400 is a two-stage dew-point generator which operates in the range of -80...+20 °Cdp (-112...+68 °Fdp). It features a touchscreen HMI, which allows the user to set the desired dew point, or create and run an automated calibration profile. The generator can also be operated remotely and integrated into customer software via the USB interface.

The 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 dew-point set points.

The DG2 has two stages of gas-flow mixing which allow it to generate dew points down to -75°Cdp (-103°Fdp). The great strengths of the DG2 are its ease of use and its flexibility in manually generating an accurate target dew point by fine tuning the gas mix via its flow metering valves. Infinite mixing is achievable within its working range.

The DG3 is our entry-level, single-stage mixing humidity generator. It is operated by manually mixing the two gas streams using flow control valves. The DG3 provides flows up to 5 Nl/min (10.6 scfh) and generates dew points ranging from -40 to +20°Cdp (-40 to +68°Fdp).

Vapor delivery system for calibration applications.

Pressure Swing dryers provide a source of very dry compressed air for use as a zero gas in humidity calibration systems, or for general laboratory applications. The Michell PSD Series Pressure Swing Dryers use two columns filled with 4Å molecular sieve desiccant, which are used alternately on a two-minute switching cycle.
