Aeroqual Ozone Monitors

Q: Do these measure ozone in the water?

No — they are ambient air monitors that detect ozone gas in the room; dissolved ozone in water is controlled with an ORP controller or a dissolved ozone probe.

Q: Which model should I choose?

The SM70 is the compact fixed monitor with relay and analog output, while the Series 900 and 930 suit installations needing 4-20 mA and multiple control outputs.

Q: Can it switch an ozone generator on and off?

Yes — the outputs are designed to control external devices, including an ozone generator.

Q: What happens when the sensor drifts?

The ozone sensor board is replaceable and can be sent back for recalibration rather than replacing the whole monitor.

Q: What power supply do they need?

The SM70 runs on 12 VDC at 800 mA from the supplied plug-in adaptor, and the Series 900 on a regulated 12 V DC 800 mA supply.

Q: How do I get a price?

Request a quote with the ozone concentration you need to detect, the outputs or alarms you want and where the monitor will be mounted — we’ll come back with the right model, sensor range and lead time.

Product Information

Key Features

Three fixed monitors — SM70, Series 900 and Series 930 — for detecting ambient ozone gas in the room, not dissolved ozone in the water
Plug and play, with real-time ozone concentration shown continuously on the display
Multiple outputs for control of external devices such as an ozone generator
Alarm options to signal ozone exceedences for health and safety
Active sampling for improved accuracy
Replaceable ozone sensor board that can be sent back for recalibration
SM70 uses Aeroqual’s GSS gas sensitive semiconductor sensor with RS232, RS485, 0-5 VDC analog and a 24 V 5 A relay output; the Series 900 adds 4-20 mA opto-isolated output and four transistor outputs
Each monitor takes one of two ozone sensor ranges, and Aeroqual does not publish those ranges or their resolution against this listing — so tell us the ozone concentration you need to detect and whether it is leak detection or workplace exposure monitoring, and we’ll confirm the model and sensor range.
