Portable Multi-Gas Detectors
When this detector senses high levels of combustible and toxic gases, it alerts you with an audible alarm, warning light, and vibrating alarm. You can adjust the alarm trigger points to suit your environment. There is also a motion sensor that sounds an alarm if the user becomes disabled.
A calibration check must be performed on the detector before each use to verify that it is working properly. The check requires a regulator and cylinder (sold separately).
Note: LEL is lower explosive limit.

Early-Warning Surface-Mount Hydrogen Detectors
This detector triggers a “caution” alert when a small amount of hydrogen is detected and a second “danger” alert if levels continue to rise. When hydrogen concentration reaches 1% by volume, a yellow warning light illuminates and the first relay closes to trigger a remote exhaust fan and/or alarm. When hydrogen reaches 2%, a red warning light illuminates, an alarm sounds, and the second relay closes to activate another remote exhaust fan and/or alarm.
Use the optional remote and cable to keep an eye on the detector’s alert status from a distance. Remote has a buzzer and the same yellow and red warning lights as the detector.

Economy Gas Leak Detectors
Check for combustible gas leaks in equipment such as pipes, valves, and storage tanks. When these detectors sense combustible gas, they alert you with a warning light and a continuous beeping sound. Unlike our other gas leak detectors, these are compact and can fit in your pocket. However, they only detect combustible gas, not toxic gas.
Static absorption detectors also indicate the presence of static that could ignite flammable gases or vapors. To ensure strong charges aren’t present, test for static absorption before entering an area to test for gas leaks.

Unlike typical leak detectors, this unit doesn’t rely only on the presence of a gas to work, making it suitable for a wider range of applications. In addition to gas leaks, it identifies ultrasonic sound caused by failing solenoids, valves, and bearings.
For systems under 10 psi, use the optional ultrasonic sound generator.
Import regulations restrict sales to the listed areas.
Acoustic Imaging Gas Leak Detectors
Locate leaks up to 10 times faster than traditional leak-detecting methods. These detectors use 124 microphones to determine the precise location and size of leaks in compressed air and specific gas systems. The screen displays a high-resolution acoustic image that’s overlaid on a digital live shot of your facility to help you visualize the leak. It also displays analytics related to the leak, such as the rate and the potential cost savings of patching your system. You can capture the on-screen view through photos and video to review later. With a built-in flashlight, they remain accurate even in low-light spaces. Light enough to carry with one hand, you can bring these detectors on the go. A 650 ft. range means you can use them from one end of your facility to another, or to detect in hard-to-reach systems.
Connect the detector to your computer using Wi-Fi or the included USB cable to quickly transfer collected data.

Environmental-Monitoring Modules for Development Boards
Keep equipment running and working conditions safe—these modules add air quality tracker capabilities to your development board. Each module gathers data on air conditions, ranging from temperature and humidity to carbon dioxide or volatile organic compound (VOC) levels. These modules easily connect to boards and other components with Qwiic cords or by soldering.
Modules with a temperature, humidity, and air quality sensor help you make sure the air is healthy in your facility. They directly measure the amount of carbon dioxide in the air.
Modules with a temperature, humidity, air quality, and barometer sensor give you the most comprehensive picture of air conditions in your facility. They directly measure the amount of VOCs and give you an estimated measurement of carbon dioxide based on VOC levels. They monitor air quality using Germany’s Air Quality Index (AQI).
