AS-500 Buyer's FAQ
Q.What replacement parts are needed?
A.The only replacement parts are the membrane & electrolyte solution.
Q.How long will the replacement parts last on the AS-500 dissolved ozone monitor?
A.The electrolyte solution ($16) should be replaced every 3-6 months. The membrane ($75) should be replaced every year, or as necessary. This will occur more frequently in water with higher turbidity or TSS.
Q.Where is the AS-500 manufactured?
A.The AS-500 dissolved ozone monitor is made in the USA.
Q.Does water quality affect electrolyte solutions replacement frequency?
A.The electrolyte replacement frequency is not directly dependent on water quality. However, higher dissolved ozone levels in the water will consume the electrolyte faster, poor water quality usually requires higher dissolved ozone levels, therefore the electrolyte would be consumed faster. Water quality normally only affects the life of the membrane cap.
Q.What is the relationship of ORP (Oxidation Reduction Potential) to Dissolved Ozone?
A.There is no direct relationship of ORP levels to dissolved ozone levels. ORP is measuring the cleanliness of the water, or the oxidation potential of the water. This is usually a measure of the oxygen, or even ozone in the water. So, it is true that there is a correlation of ozone to ORP, however, depending upon water quality this relationship will vary from water to water.

Q.How do I calibrate my dissolved ozone monitor?
A.Unlike most ambient air ozone monitors which can be sent back to Ozone Solutions for calibration, dissolved ozone monitors should instead be calibrated at the customer site for best results. The industry standard for calibrating dissolved ozone monitors generally accepts chemkits or single analyte meters as valid references to calibrate against. For further detail, refer to our K-7402, SAM-2, or SAM-3 products, which are listed on the Dissolved Ozone Monitors page.
Q.Can the AS-500 handle salt-water?
A.The AS-500 dissolved ozone monitors have not been tested in saltwater. We think the sensors would not be reliable in that type of application due to high ionic strength/salt concentration and unknown levels of dissolved organics and suspended particles. e.g., membranes clog up easily in some of those conditions. The unit we recommend for saltwater is the DOM-1. The sensing technology in the DOM-1 does not come into contact with the saltwater.
Q.What is the maximum cable length between the probe & display?
A.The maximum cable length for the AS-500 dissolved ozone monitor is 100-ft. The cable is shielded to eliminate EMF interference.
Q.How often does this monitor require calibration?
A.The manufacturer recommends a yearly calibration. The readings of all ozone monitors will start to stray over time and need to be corrected when possible.
Q.Will I get a tracking number when my item ships?
A.For customers who chose UPS: a tracking number is automatically sent via e-mail before the order leaves our warehouse.
For customers who chose FedEx: a tracking number is usually available if requested by either e-mail or phone.
For customers who chose USPS: tracking numbers are only created by USPS for select services, such as insured packages. We will be happy to provide available tracking information if requested.
