True Wireless® Gas Detection

Gastronics pioneered the first all-in-one wireless gas monitor in 1999 where the radio is an integral part of the gas monitor. The True Wireless gas detection system offers the most economical solution for monitoring gases from remote locations. Our UHF/VHF monitors offer up to 6 watts of power and are capable of transmitting in and around steel structures and over long distances in worst case scenario. True Wireless is also available for ISA100.11a MESH Networks and M2M GPRS Cellular Radio.
