OMD-351 Ambient Air Monitor
Online Oxygen Monitor with Alarms & Battery Backup

应用领域
The OMD-351-O2 Ambient Air Monitor is designed to measure and
assure the appropriate levels of both oxygen in an enclosed or confined area. Personnel safety is a primary issue in nearly every industry and is magnified within confined spaces where oxygen depletion
or asphyxiation due to a leak in an inert gas container can quickly
and unexpectedly take place.
The OMD-351-O2 is designed with an easy to use interface with
features that are optimized for safety and mitigate the dangers of
confined spaces and oxygen deficiency. The analyzer comes with 2
pre-configured oxygen concentration alarms that match the OSHA
recommendations of 19.5% and 20.0%. Alarm functionality comes
in the form of 2 fully adjustable, form C non-latching, relay contacts,
an integral audible buzzer and local LEDs’ loaded into the front of the
unit. The unit also has a built in POWER FAIL relay contact.
The unit comes standard with an integral battery backup which helps
accentuate “brown out” conditions. With this standard feature,
power outages will not interfere with a properly working monitor.
The standby power source uses a rechargeable lead acid battery.
The oxygen sensor used in the OMD-351-O2 is based on the galvanic
electrochemical fuel cell principal. The sensors are self-contained
and minimal maintenance is required – no need to clean electrodes or
add electrolyte.
