Uni Portable Ozone Monitor

The WatchGas UNI is a compact and easy to use Portable Toxic Gas Monitor and is also available as a single gas monitor for many other gases. Available with wide range of sensors that are suitable for many types of gases, such as special sensors for oxygen. In addition, the WatchGas UNI Sustainable also offers a wide choice of sensors for toxic gases. With its bright LED display and loud 95dB acoustic alarm, no alarm will pass you by, ensuring your safety with regard to gases.
The UNI offers a simple portable solution for a wide array of toxic gases and O2 applications. With a large LCD screen, the UNI provides maximum readability in the field. Six bright red LEDs and a loud beeper provide unmistakable alarm notification. It even has a built-in vibration alarm, for extra peace of mind in noisy work environments and when working with hearing protection.
The UNI is constructed using strong and durable materials, to provide protection in the harshest of environments. It also rests easy in your hand, with an easy-grip, rounded surface for optimal usability even when wearing multiple layers of protective clothing. The UNI series can easily be bump tested and calibrated with the WatchGas Mono/Multi Dock.
