I would like to commend Ozone Solutions for their quality workmanship and superior customer service. Ozone Solutions provided us with a well-designed ozone sparge system with plenty of room inside to move around and perform the operation and maintenance on the ozone system. You were extremely helpful during the engineering, planning, and building process...

Overview

The AS-500 is a very versatile ozone meter that can be used in many different applications. The sensor can work at pressures from 0 - 30 PSI. This allows the sensor to be used in-line with no extra flow cell!

What makes the AS-500 different?

The AS-500 has a leg-up on other dissolved ozone monitors because of it's rugged no-nonsense sensor probe. It is not a high-precision instrument when compared to some other meters, but most dissolved ozone meters require very tightly controlled water pressure and flow in order to achieve ccuracy whereas the AS-500 does not. The probe can be installed directly into water piping and operate reliably and consistently without being overly sensitive to changes in pressure and flow.

Frequently Asked Questions

  1. What replacement parts are needed?
  2. Where is the AS-500 manufactured?
  3. Does water quality affect electrolyte solutions replacement frequency?
  4. What is the relationship of ORP (Oxidation Reduction Potential) to Dissolved Ozone?
  5. How do I calibrate my dissolved ozone monitor?
  6. Can the AS-500 handle saltwater?
  7. What is the maximum cable length between the probe & display?
  8. How often does this monitor require calibration?
  9. How long will the replacement parts last on the AS-500 dissolved ozone monitor?
  10. Can I measure ozone levels above 5 ppm?
  1. What replacement parts are needed?

    The only replacement parts are the membrane & electrolyte solution.

  2. Where is the AS-500 manufactured?

    The AS-500 dissolved ozone monitor is made in the USA.

  3. Does water quality affect electrolyte solutions replacement frequency?

    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.

  4. What is the relationship of ORP (Oxidation Reduction Potential) to Dissolved Ozone?

    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. Please review the following link for more information: www.ozonesolutions.com/ORP_Ozone.html

  5. How do I calibrate my dissolved ozone monitor?

    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-7404 or I-2019 products, which are listed on the Dissolved Ozone Monitors page.

  6. Can the AS-500 handle saltwater?

    This unit has 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.

  7. What is the maximum cable length between the probe & display?

    The maximum cable length is 100-ft. The cable is shielded to eliminate EMF interference.

  8. How often does this monitor require calibration?

    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.

  9. How long will the replacement parts last on the AS-500 dissolved ozone monitor?

    The electrolyte solution should be replaced every 3-6 months. The membrane should be replaced every year, or as necessary. This will occur more frequently in water with higher turbidity, TSS or high dissolved ozone levels.
