The Cermet II I.S. is an all-in-one humidity meter that is easy to install and used to measure the moisture content in flammable or common gases. Its special design is suitable for hazardous environments. It includes an inherently safe transmitter Transmet I.S. and a safety application control module Cermet II I.S. Under the stainless steel casing, the sealing protection level of Transmet I.S. reaches IP66 (NEMA 4X). The Cermet II I.S. control module is a 19 'rack mounted component with display, voltage regulator module, and safety barrier, suitable for safe areas. This humidity meter provides all necessary interfaces for users, including multi unit display, alarm, analog and digital output, etc. The cable between the control module and the transmitter through the safety barrier can be up to 500m in length. highlight ATEX, FM, and CSA certifications Pressure sensor input Measurement accuracy ± 1 ° C dew point User selectable measurement unit Up to 4 channels of alarms Wide range, calibration range -100~+20 ° C dew point Analog and digital outputs

Other similar materials are available for selection Maximum length of 500m (depending on the technical specifications of the cable) safety The Cermet II I.S. humidity meter complies with the standard BS5345: Part 1:1989 and other relevant European safety regulations for the operation of sensors in hazardous environments and the sampling system for analyzing gases. The Cermet II I.S. control module must be placed in a non hazardous location (or in an optional EExd explosion-proof box). Transmet I.S. is ATEX certified and can be used in hazardous environments II 1G EEx ia IIC T4 after using a pair of isolated or Zener safety barriers on signal and power connections. Transmet I.S. also meets FM certification (USA) for CL1, Div1, GpA, B, C&D, T4, as well as CSA (Canada) certification for Ex ia (Class 1, Groups A, B, C&D).
