The Polytector III G999M is the best choice for personal protection against a wide range of gas dangers in mining and in Ex-Zone 0 and clearance before entering shafts and confined spaces. Measurements before confined space entry are done with the integrated pump. If a threshold value is exceeded, the G999M will warn its wearer in three ways: via light signals, vibration and a loud horn (103 db(A)). Equipped with an optional radio module, up to 10 portable gas detection devices of the G999 series can be connected to the Connected Safety Monitor TeamLink.
