Simple, quick installation
The instrument is easily mounted on a wall
or structure. After installing the sensor,
and plugging the line cord into a 110 VAC
outlet, PointGard II is ready for operation.
Sensors are pre-calibrated before ship-
ment, so calibration is not necessary at
start-up. The simple menu guided user
interface is accessed through 3 buttons
on the front panel of the instrument.
Proven DraegerSensor technology
The heart of the PointGard II is the elec-
trochemical DraegerSensor®, the latest
development in gas sensing technology.
The DraegerSensor is designed for accura-
cy, stability, and long life. Temperature
compensation of the sensor signal has
been optimized and cross sensitivity to
other gases minimized, ensuring an accu-
rate reading of the target gas concentra-
The gas concentration is displayed on a
bright LED display. In an alarm condition
the horn and the strobes are activated.
The measuring ranges can be selected
within a number of set points.
PointGard II has an industry standard
4 to 20 mA output, so the current gas
concentration can be transmitted to a
central control system. The three on-board
relays allow for the connection of additional
alarm devices in a remote area. The alarm
set points can be programmed to any
value, and the relays can be programmed
as latching/non-, acknowledgeable/non-
