Crowcon T3 Multi Gas Detector
The Crowcon Tetra 3 is a multi gas detector and can detect a combination of 2, 3 or 4 gases. The O2 sensor includes a 3-year warranty. Configurations also include an LEL sensor, hydrogen sulphide (H2S) and carbon monoxide (CO) sensor. Other sensors are available to allow the Tetra 3 to adapt to other industries.
The Tetra 3 multi gas detector is effective in harsh environments thanks to its rugged design and IP65/67 rated casing. This makes it water and dust resistant and allows it be briefly submerged in water. The T3 can be securely attached to clothing using the integral alligator clip.
Crowcon have ensured the gas T3 is also reliable and have included a triple alarm system to alert the wearer to the presence of gas. This includes a 95dB alarm, a bright blue/red visual alarm and an internal vibrating alarm.
