About Sierra Monitor Corporation (SMC)
SMC offers a full range of high-quality gas detectors, manufacturing everything from single, fixed-point to system-wide, multi-point and customizing each gas detection system to each specific application as needed.
Sierra Monitor's gas detectors detect literally dozens of toxic/dangerous gases, alert you to oxygen deficiency, and are equipped with numerous advanced technologies, such as protocol converters and remote management systems, that make them exceptionally easy to use.
Nine of the most popular SMC gas detectors and related products are listed below:

Sentry IT Fire & Gas System
Sentry IT offers best-in-class performance for fire and gas detection with integrated IT sensors, a modern, comprehensive controller, and compatibility with numerous interfaces (both new and legacy).

Smart Gas Detectors (IT Series)
These gas detectors are highly flexible since they have 4-20 mA, Sentry and Modbus output capability, and their displays, diagnostics, and all else is fully up-to-date.

Specialty 4-20 mA Analog Gas Sensors
These are essentially equivalent to the IT Series but tailored to a variety of specific gases.

Two-Wire Gas Sensors
These are loop-powered gas detectors that are fast and easy to install and yet full of upscale features, like continuous self-diagnostics, a 16-character display, and an industry leading calibration length.

Gas Monitors
This is SMC's "basic" line of gas alarms/monitors, simple audio/visual alarms that reliably detect gas presence over a predetermined level.

Open Path Gas Detection
The SMC Open Path covers expansive areas, operates in real time, is ruggedly built for harsh environments, and has very low incidence of false alarms.

Gas Detector Calibrators/Accessories
SMC calibration/sensor accessories fine-tune and enhance the performance of your gas detection system.

Flame Detectors
These devices alert you to fire/flames in the earliest stages with a multi-spectrum UV and/or Infrared sensor. They are custom-fit to various industrial applications and almost never have a false alarm.

Customized Systems
SMC routinely customizes special gas detection systems for a wide range of applications and for commercial, industrial, and military clients.
