This product is now obsolete and has been replaced by the MDM300.

The hygrometer of choice for the measurement of dew point temperature or moisture content in hazardous area gas applications.

Cermax I.S. provides raw performance, rugged reliability and advanced features for measuring the dew point of non-flammable and flammable gases within petrochemical, natural gas plants and other hazardous areas. It provides the site chemist and operational staff with an effective means to check the moisture concentration at any point in their process.

Cermax I.S. is also perfect for any industrial application requiring safe measurement of flammable gases, such as hydrogen used as coolant for electricity generator sets or as a controlled furnace atmosphere for heat treatment of metals.

Easy Operation - Cermax I.S. is a self-contained system - no external services are required. Simply connect a clean sample gas to the Swagelok® inlet port, turn on the power and within seconds Cermax displays the measured moisture value of the sample gas. For process gas applications, sample system modules are available that couple directly to the unit.

Extremely Fast Response - Cermax I.S. was designed for quick speed of response as its key feature. With an inherently fast Ceramic Moisture Sensor and a minimum volume stainless steel sample path, Cermax has a head start on getting you the information you need. Cermax goes even further adding a user selectable field operation mode that allows even ppm level measurements to be made in a few minutes. The result is a world-class hygrometer with superior performance.

High Accuracy and Repeatability - The combination of advanced sensor technology and measurement circuitry give Cermax a standard measurement range from -100 to +20°C dew point with indication down to -120°C and up to +30°C dew point. Cermax offers a measurement accuracy of better than ±1°C dew point over the range of -60 to +20°C dew point and better than ±2°C from -100 to -60°C dew point. Resolution is 0.1°C dew point across the entire calibration range.

Intrinsically Safe Certification - Cermax I.S. is certified by Baseefa (2001) Ltd for use in hazardous areas to II 1G ATEX ia IIC (155°C) T3 and also FM (USA) listed to intrinsically safe CL1, Div1, GpA, B, C & D T3C and CSA (Canada) to Ex ia IIC T3 (Class 1, Div 1, Groups A, B, C & D).
