Fixed Type Gas & Flame Detection

Solid State Gas Sensor Monitors 20X/200X

Sierra Monitor’s 20X/200X gas sensor monitors consist of three gas sensor modules used to monitor combustible gas, Hydrogen Sulfide (H2S), and Carbon Monoxide (CO).

The 20X/200X monitors are based on solid state (semiconductor) technology, a simple and robust method of detection capable of detecting low points-per-million (ppm) levels of gases.

Though the 20X and 200X monitors look different in structure and size, the two monitors function similarly. The solid-state type sensor and associated electronic circuitry ensure trouble-free, long-term operation. There are no pumps, filters, or chemical cells to replace or maintain. With the exception of periodic calibration to verify the alarm setting, no attention is required after installation. The standard configuration has a normally operating relay, with a fail-safe normally operating closed relay being field selectable.

The Solid State Gas Sensor Monitors 20X and 200X are approved and certified by a variety of third party agencies, including UL and CSA. These approvals and certifications assure our customers that we carry only the highest quality of products and performance.
