Configuring the PID Sensor
Updated June 26, 2025
The Photoionization detector (PID) measures and reports the overall local concentration of volatile organic compounds (VOCs) in the local environment when used with the default configuration within Blackline Live.
This article provides information about configuring the PID sensor in Blackline Live, including specifying a target VOC (single or custom), selecting alarm thresholds, as well as STEL and TWA exposure values.
Blackline Safety devices may include default sensor threshold values for convenience; however, these defaults may not align with the regulatory or safety requirements of your jurisdiction. Consult with your Environmental Health and Safety group for your organization’s recommended PID Sensor thresholds and overall sensor configuration.
Blackline Safety recommends always reviewing and updating threshold settings before deploying devices to ensure compliance and to maintain appropriate protection levels for your work environment.
