Safeguard Analytics manufactures high quality gas detection sensors, safety control systems and gas process analyzers. Our team of scientists, engineers and marketing professionals have years of experience in the global gas detection market creating innovative and distinctive products. We design our products by keeping them simple and intuitive. We deliver safe and reliable solutions for virtually any commercial or industrial gas sensing application.


Model SA-1N4 gas detection sensors are designed to detect and monitor toxic, oxygen and combustible gases in ambient air. Sampling is via diffusion. The design features a full range of sensor technologies; electrochemical sensors, photo ionization detectors, non-dispersed infra-red and a multi spectrum combustible gas detection sensor. Specific gas type is determined by installing a selected Model SA1 smart sensor module. Each sensor module stores gas type, range of sensitivity and the last zero and span calibration data points.

All electronics are contained within a NEMA 4X weather proof enclosure suitable for installation in non-hazardous locations. Model SA-1N4 gas detectors feature non-intrusive calibration using a small magnet or an Android™ phone or tablet and the Safeguard OpCheck application. The col-or graphic display provides simple and intuitive user interface with real time readings and full script service instructions. Device status is readily determined by screen color; green normal – no alarm condition, yellow alarm level 1, red alarm level 2 and blue indicates a fault condition.
