3701-030 Dynagard Stand-alone System, Oxygen (O2) by GfG
Single-point Area Monitors
Dynagard AutoCal® monitors are single point detection instruments that accurately measure toxic gases and oxygen levels. Alarm lights on the front panel illuminate and an internal horn sounds when gas concentrations are exceeded.
Simple and effective
The units accurately display values on a large backlit LED and can transmit a linear 4-20 mA output. AutoCal® calibration and maintenance is done effortlessly through front panel push-buttons. Smart sensors enable the user to change measuring ranges or gas types in the field without a need for additional programming. The Dynagard is equipped with onboard relays for two adjustable alarm points. It also has one sensor fault for local connection and activation or deactivation of external devices like strobes, fans, auto dialers etc.
Features
- AutoCal® automatic calibration
- Smart sensor technology
- Digital display / control connection
- Internal push-button alarm settings
