Measure and display real-time indoor ventilation quality. These meters operate with the included universal AC adapter or six AAA batteries. They have automatic baseline calibration. Transfer and view data on your computer using their USB cable and software.

When your work area has too much or too little oxygen, these detectors alert you with an audible alarm, warning light, and vibrating alarm. You can adjust the high and low alarm trigger points to suit your environment.

A calibration check must be performed on the detector before each use to verify that it is working properly. The check can be performed with the press of a button.

The detector with a nonreplaceable battery should be thrown away at the end of its two-year lifespan.

When these detectors sense high levels of carbon monoxide, they alert you with an audible alarm, warning light, and vibrating alarm. You can adjust the alarm trigger point to suit your environment.

A calibration check must be performed on the detector before each use to verify that it is working properly. The check requires a regulator, tubing, and cylinder (sold separately).

The detector with a nonreplaceable battery should be thrown away at the end of its two-year lifespan.

When these detectors sense high levels of hydrogen sulfide, they alert you with an audible alarm, warning light, and vibrating alarm. You can adjust the alarm trigger point to suit your environment.

An audible alarm and warning light alert you to the presence of propane. This detector has a relay for connection to auxiliary alarm systems. A programmable timer allows you to set whether the relay alarm is triggered immediately, or after 4 or 8 minutes of continuous gas exposure. The reset button suspends the alarm and restarts the cycle for 5 to 8 minutes in case of false alarm.

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.

Check your indoor air quality (IAQ) by measuring the amount of particles present. These counters are often used to monitor dust levels in workshops, check for particles in classrooms, and measure filter efficiency in HVAC systems. The sensor probe detects and identifies particles of six different sizes, helping you confirm that your clean room complies with ISO Class requirements. First, use the zero count filter to establish a baseline before taking a sample. Then, either measure the amount of air particles detected within a set time range or the amount of air particles detected within a certain air volume. Counters store up to 10,000 readings in their internal memory, and you can transfer data to your computer via Ethernet or USB connection—no special software required. Compact, lightweight, and battery powered, these counters are portable and able to operate in tight spaces. They’re CE marked as compliant with European health, safety, and environmental standards.

Identify a variety of small leaks quickly and access hard-to-reach areas with the flexible probe. An audible signal increases in intensity the closer you get to the leak. Intrinsically safe for Class I, Divisions I and 2, Groups A, B, C, and D hazardous locations.

These detectors are fluorescent green. Bubbling action at the source provides quick and reliable leak detection, saving time and energy costs. These noncorrosive, nonflammable detectors find leaks in pipes, tubes, fittings, tanks, and cylinders. They adhere to vertical surfaces. All wash off with water.

Use a UV flashlight for enhanced viewing.

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.

This detector converts ultrasonic waves to an audible sound so you can find 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.

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.

Detect halogenated refrigerants such as HFCs, CFCs, and HCFCs. Access hard-to-reach areas with the flexible probe. This unit can detect leaks as small as 0.1 oz. per year in air conditioning and refrigeration systems. An audible signal increases in intensity as you approach the leak.

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 an air quality sensor identify spikes in VOC levels to track air quality changes. Instead of directly measuring VOCs, they measure how much the VOC level has changed in the last 24 hours.

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).
