The GDS-68SXP Odorant Monitor uses industry-proven electrochemical sensor technology to measure the level of odorants in natural gas. Sensors are available for mercaptans, tetrahydrothiophene (THT) and blends such as Spotleak ® by Arkema and Scentinel ® from Chevron Phillips.

Scentinel ® from Chevron Phillips. The GDS-68SXP Monitor offers an alternative to expensive analyzers or constant monitoring using pull tubes. While federal regulations still require human ‘sniffers’, the GDS-68SXP provides a cost-effective, automated and objective way to continuously measure and report odorant levels throughout a natural gas distribution network.

Reliable Measurements Day & Night

The GDS-68 SXP Odorant Monitor automates the entire measurement process. Before displaying the calculated value, each result is verified for proper gas flow, zero drift, overrange, sensor response and more.

Designed for Remote Environments

The GDS-68SXP is designed to be installed in remote, unattended locations. Power usage is less than 10 watts, making solar-powered operation practical and reliable. Automatic calibration allows the GDS-68SXP to periodically perform System Calibration cycles on daily, weekly or monthly intervals. Error conditions are reported as multi-level fault values, allowing remote diagnosis via the 4-20mA analog output or RS-485 MODBUS interface.

Advanced User Interface with Bluetooth ® Wireless Technology

The GDS-68SXP features a large, easy-to-read color screen that displays the current reading, system status, time to next measurement and more. The companion GDS Connect iOS app for iPhone ® connects to the GDS-68SXP via an internal Bluetooth wireless interface and allows the user to monitor or change settings and issue commands if GDS-68SXP user security settings allow.
