Multi-Gas Monitor

Tetra monitors from one to four gases with a single button that controls all functions. A backlit at-a-glance display provides simultaneous viewing of all gas readings, alarm conditions and battery life. Tetra units are rugged despite its compact size and low weight (approximately 1 pound). Tetra gives rapid and effective warnings of the presence of gas when hazardous levels are detected. The user is alerted by extremely bright blue and red LED beacons and a powerful 90-dBA alarm. Sensors are available for oxygen, flammable gas and a full range of toxic gases.
