Hygrometer sets the standard for power
generators
Michell Instruments has produced an intrinsically safe portable hygrometer.
Cermax IS is a user-friendly hygrometer and is both CENELEC and FM certified for use in gas group IIC Cermax IS provides three important application solutions for engineers within any power station environment: Being IS in design, the instrument is ideally suited to measuring the dewpoint of Hydrogen that is commonly used as a cooling gas on generator sets.The instrument can also be used to confirm the moisture content of sulphur hexaflouride (SF6) that is used as an arc quenching gas on high voltage switchgear

Michell Instruments has launched the high performance Cermet II hygrometer for the on-line monitoring of moisture content in a wide range of process gases.
Better measuring of moisture in natural gases
With the introduction of Promet, Michell Instruments has developed a specific solution to the issue of moisture measurement in natural gas
The third and most common use for any portable dew point meter is that of checking the quality of dry compressed air, used throughout the power industry.
Cermax IS provides raw performance, rugged reliability and advanced features for measuring the dew-point of nonflammable and flammable gases within petrochemical and natural gas plant areas.
This means the advanced portable hygrometer can provide the site chemist and operational staff with an effective means to check the moisture concentration at any point in their process.

The market is soon likely to see the introduction of a full range of humidity sensors designed to provide the exact level of function, flexibility and manual control required in each application.
Dewpointmeter monitors Millennium Seed Bank
The Royal Botanic Gardens (RBG) is using a Dewmet cooled mirror dewpointmeter from Michell Instruments to monitor equilibrium relative humidity (ERH) levels.
Cermax IS is easy to use, fully self-contained and no external services are required, meaning that within seconds, the device is ready to display the measured dew point of the sample gas under test.
The advanced user interface allows you to decide whether to make a simple measurement or to perform more complex functions like pressure compensation, range selections, input scaling, data-logging, etc.
The versatility of Cermax IS means that for more demanding process applications a range of 'bolt-on' sampling systems are available.
While developing Cermax IS, the engineers at Michell Instruments recognised the users requirements and the importance of a fast speed of response.
The intrinsically safe hygrometer has been developed with this feature in mind.
With an inherently fast Cermaic Moisture Sensor and a minimum volume stainless steel sample housing, Cermax IS has a substantial head start on the competition.
The product also has a user selectable field operation mode and this allows even ppm level measurements to made in as little as a few minutes.
The portable dew point meter prides itself with high accuracy and reliability.
The combination of advanced sensor technology and measurement circuitry give Cermax IS a standard measurement range from -100 to +20C dew point and indication down to 120C and up to +30C dew point.
Cermax IS is the latest addition to Michell Instruments' range of versaltile hygrometers suitable for a variety applications.
