Gas Detection Sensors: 20+ Gas Coverage Options

A leading gas detection program begins with configurable and reliable gas sensor technology. As a result of our customizable configurations, swappable cartridges, and strong relationships with sensor manufacturers, Blackline offers one of the largest portfolios of gas sensors on the market. We use only the highest quality sensors from leading providers including Ion Science, City Technology, MIPEX, Gas Sensing Solutions (GSS) and NevadaNano. Constant evolution of our cartridge housings ensure the latest sensors can be deployed using your current Blackline devices, and the same device can be configured for different hazards as needs change.

Modular Gas Sensors for Maximum Versatility

With thousands of gas sensor configuration options, we make it easy to get the most from your gas detection budget. Our G8 personal gas detectors, G7x satellite gas detectors, and EXO area gas monitors each feature a modular, plug-and-play gas sensor cartridge system.

G7-with-three-cartridges-700x500

Single-gas Diffusion Cartridge
Our single-gas diffusion cartridges support you with a choice of over 20 sensors, including PID Gas sensors.

Multi-gas Diffusion Cartridge
Our multi-gas diffusion cartridges support up to five gases when equipped with a dual-toxic COSH gas sensor (CO and H2S). Easily swap from single gas detection to a multi-gas sensor on the same device.

G7 Multi-Gas detector with pump

Multi-gas Pump Cartridge
Designed for remote sampling, our multi-gas pump cartridge supports confined space entries and leak-check surveys. This cartridge supports both diffusion and pump operation modes. Pump detection is available for G8, G7x, and EXO devices.

Area Gas Monitoring Cartridge

With a customizable four-gas cartridge pre-loaded, and the option to add a preset combination of four gases in the gas expansion module, Blackline EXO covers a wide spectrum. An optional integrated gamma radiation sensor can be specified when ordering EXO to further extend detection capabilities.

Gas Cartridge & Sensor Info

Our G8 and G7x personal gas detectors and EXO portable area gas monitors can equip and swap between the sensors listed below.
Many gas sensors can be combined in a multi-gas cartridge, making thousands of potential gas detection portfolios accessible via a single device.

G6 single gas monitors come equipped with one of the following fixed sensors: CO, H2S, O2, or SO2.

Some sensor types cannot be combined in a multi-gas cartridge without impacting accuracy.
This list is not exhaustive of all available sensor options. Legacy devices may not support newer sensor versions.

If you have questions about a particular sensor or custom configuration, please contact our expert advisors.
