The A14-A11 (formerly O-14P) ozone monitor is the "Cadillac" of ozone control. A remote sensor/transmitter allows ozone measurements in locations separate from the display. The display provides real-time ozone readings. Three adjustable relay outputs carry up to 10A each. 4-20mA signal included!

Multi-Channel Capable!
The A14-A11 Multi channel configurations are available through the drop down boxes above. Multi-channel units with 1 through 9 channels can be selected. Multi channel configurations , allowing you to quickly and easily monitor ozone levels in various areas with one control panel. Call ((712) 439-6880) or e-mail us ( for further details!

Auto-Test Generator Accessory
The A14-A11 is available with an optional Auto-Test Ozone Generator that mounts on the sensor, testing ozone response daily. If the sensor fails to respond to ozone, the user will be alerted to the failure - preventing accidental ozone exposure due to aged or failed ozone sensors. When selecting this option use the drop down box to select the option that matches the channel option you choose.

Sensor Range
A14-A11 come standard with a 0 to 2 PPM sensor transmitter (0-20 PPM available.) To order the A14-A11 in one of these configurations Call ((712) 439-6880) or e-mail us ( for further details !
