Personal 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 user 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. Response Time: T90 in 10 Seconds Sensor Life: 60 Months (Approximately) Temperature Compensation: Integral Visual Alarms: Panel Mounted LED's Warranty: 12 months Analyzer & Sensor *Accuracy at constant conditions Optional Configurations: 24V DC Input Power Remote Oxygen Sensor (OMD-351-O2-Remote) The oxygen sensor used in the OMD-351-O2 is based on the galvanic electrochemical fuel cell principal. All oxygen sensors are manufactured in house by Southland Sensing Ltd. under a strict quality program. The sensors are self-contained and minimal maintenance is required - no need to clean electrodes or add electrolyte.
