Specializing in Electronic Confined Space Monitoring. Exclusive dealer of the LifeLine System. Safe Environment Engineering is proud to announce the next generation of the Life line Personal Safety Monitor (PSM). The monitor, designed and engineered to the demanding standards of the Life line System and Safe Environment Engineering, utilizes the latest technology to provide two-way voice communication and telemetry/data acquisition in a proactive real-time fashion. The PSM has been reduced in size over 75% and now measures 4"x2.2"x1". The dramatic reduction in size facilitates a lighter and easier to wear unit. Now, about the size of a cellular phone, the PSM can be easily be carried in a pocket or worn on a belt, vest, or harness, leaving the user without the need to carry another piece of gear. This is the industry's most compact integrated 4 gas detector . Call Mr. Hutchinson for a free onsite demonstration
