  •     10.0 ppm range = 0.1 ppm resolution
• Graphic Display: Indicates the current ozone level and past 12 hour trend graph
• Response time: Within 8 seconds
• Measurement principle: HMOS (heated metal oxide semiconductor) sensor
• Size: 11" long x 4.5" deep x 8" wide
• Weight: 1 lb
• Power requirements: 12 VDC at 300 mA. - 120 VAC to 12 VDC Adaptor included.
• Relay Outputs: 10 amp relay 
• Analog output: 4-20 mA output linear with ozone level
• Calibration: Replace your sensor annually 

Replaceable Sensor:

The OA-1 Ozone Alarm uses the SM-3 Sensor for ozone detection.  This is a field-replaceable sensor chip that can be replaced every 6-months - 1-year to maintain ozone detection accuracy without ever having to remove the OA-1 from service.  Simply pull the old sensor off, and replace it with new at a cost comparable to calibration. 

As the replacement sensor has a similar cost to calibrating an existing sensor, long-term sensor + calibration cost will be lower than any other comparable sensor options that require calibration, then, eventual sensor replacement.

Data Logging:

Data logging with the OA-1 Ozone Alarm is possible with an external data logger such as the DL-3.  Using the 4-20 mA output signal from the OA-1 the DL-3 can log and save gas measurements. 

Wireless Monitoring & Data Logging Kit:

Use the Wireless Monitoring & Data logging Kit with your fixed mount monitor to connect it to the internet allowing access from anywhere. Receive Instant notifications with free text and email alerts. This is a great addition for your fixed mount gas detector.
