Sierra Monitor Analog Gas Sensors have a variety of calibration and sensor options to insure accurate and reliable monitoring of hazardous gases.

A variety of accessories help provide accurate and reliable monitoring of hazardous gas conditions. These options aid in providing a system designed to meet the specific needs of the user.

Calibrators - a selection of calibrator systems and calibration gases to enable the user to easily and properly calibrate the gas sensor modules

Sample Draw Products - used in applications in which the sensor cannot be installed directly at the gas sensing location, due to poor accessibility or the harshness of the environment

Mounting options – Sensors are available in NEMA 4X enclosures and in some cases available with sensors remotely mounted from the transmitter.

Rainshield - The Model 5311-00 Rainshield is mounted over the sensor head to protect the sensor from direct exposure to rain, hosedown and other splashing liquids.

Duct Mounting Fitting - The Model 5394-00 Duct Mount fitting facilitates installation of the gas sensor module onto an air duct. The fitting also includes the 5360-00 calibration gas delivery fitting so that calibration gas can be delivered to the sensor without removing the module from the duct.

Battery Backup – The battery back-up system provides operating power when AC power drops below 90VAC. Includes battery, AC line filter, two battery charging modes, and a 12 to 24 VDC converter.

Calibration Adapters - The Sierra Monitor gas sensor modules are designed for easy calibration of the sensor modules. The standard calibration adapter screws over the head of the sensor.
