Where should the gas detector be located?
The ozone gas detector should be installed in the ozone generator room near the equipment between the ozone generator and the destructor. Additional gas sensors may be required for additional damage areas spaced more than 5 m / 16 ft apart. Another ozone gas detector (or ozone detector tube) shall be placed to monitor the exhaust flow. The goal is to be alerted to an ozone leak as soon as possible so that safety measures can be taken to stop and fix it and keep people safe.
At what height should the gas detector be installed?
Pure ozone is heavier than air, but it doesn’t necessarily settle to the floor because it easily mixes with the air. The gas detector/sensor should be mounted approximately 0.6 m / 2 ft from the floor between the ozone generator and the destructor.
How many gas detectors are needed?
JXCT’s ozone gas detectors have a sensor range of approximately 465 m2 / 5,000 ft2. The number of gas detectors will depend on the size of the ozone room, the number of generators/destructors there are inside the room and whether you are using a gas detector or a detector tube to monitor the exhaust air stream. Our knowledgeable Sales Managers can help you determine what is suitable for your application.
What is a crash test? Why do crash tests?
A bump test is a brief exposure of the sensor to the target gas. A bump tests verifies if the sensor is responding and the alarm is functioning.
How often should an ozone gas detector be hit tested?
At a minimum, the ozone detector should be bump tested once a month as part of the monthly maintenance plan for the device. There is no limit on the number of bump tests; they may be done more often depending on application and the comfortability/confidence level one has in the device and how it responds. If a bump test fails, a full calibration should be done. Bump test dates and results should be written down in a log book.
What is calibration? Why calibrate?
Calibration is the exposing of the sensor to a certified concentration of gas for a particular length of time. Calibration verifies that the gas detector is providing an accurate reading.
How often should an ozone gas detector be calibrated?
At a minimum, the gas detector should be calibrated every 6 month. More frequent calibrations may be required depending on application, regulatory laws, sensor response and exposure levels to the gas. If a bump test fails, a full calibration should be done. Calibration dates and results should be written down in a log book.
What is the lifetime of the ozone sensor?
The lifespan of an electrochemical ozone sensor is approximately 2 years (application dependent).
Additional information about ozone sensors.
Ozone is a sticky gas, meaning it adheres to surfaces like calibration tubing. Use a Teflon lined tube no longer than 1 m / 3 ft during calibration so the gas doesn’t saturate and adhere to the tubing, weakening the concentration of gas that reaches the sensor.
A JXCT ozone gas detector will never have a splash guard installed on it. The splash guard would interfere with the sensor, being able to accurately read the gas levels because ozone is a sticky gas.
When calibrating an ozone sensor, you can use a chlorine gas generator or an ozone gas generator.
