Accudata’s new GVM-Alert is proving very popular with our rental customers. Designed, like the Accudata GVM-1, for extreme ease of use, the GVM-Alert doesn’t really need a user manual although written instructions are included. 
Accudata GVM-Alert with Accudata GVM-1, a two-stage wireless alarm
The transmitter unit sits in the case alongside the GVM-1. The receiver unit with sounder and LEDs may be used up to 30m away to warn by flashing LEDs and an audible alarm (that may be switched off by the user) if levels of ground-borne vibration exceed either of the two user set levels of Peak Particle Velocity (PPV).
