SI-100R Fixed Gas Detector
SI 100 R is a full function fixed gas detection head, with options for flammable gas (Catalytic pellistor and NDIR), oxygen and toxic gas detection. In excess of 30 sensor options are available.
The device is ATEX approved explosion proof, and has a local display allowing gas levels to be read and the device to fully configured without opening the casing. In addition to an industry standard 4-20mA output signal the SI-100 R also carries onboard alarm and fault relays.
