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.
