Pool and Spa Sensors for Water Quality Monitoring

Ready pools, spas and aquatic attractions for the summer season with Sensorex pH/ORP probes
Garden Grove, California (March 22, 2017) – As the weather warms and pool equipment is being readied for the new season, replacement of pH and ORP sensors is a crucial part of the maintenance process. Monitoring water quality with Sensorex’s cost-effective pH and ORP sensors impedes algae growth, reduces surface erosion and increases swimmer enjoyment.

pH and ORP Probes

The Sensorex S465 Series are a direct replacement alternative to Acu-Trol® pH and S420 Series replace Strantrol® pH and ORP probes.

The Sensorex S465 Series are a direct replacement alternative to Acu-Trol® pH and ORP probes, and the robust S420 Series replace Strantrol® pH and ORP probes. In addition to a reasonable price point, both Series are easy to integrate into existing systems and offer long, reliable service life. Sensorex’s advanced sensor technology delivers accurate measurement over a range of 0-14 pH or +/-1000 mV for ORP. Sensors use a higher volume of Sensorex’s proprietary polymer sensor reference gel for longer service life.

Proper disinfection of aquatic environments is a delicate balancing act. Over-chlorinate and cause bather discomfort and equipment erosion; under-chlorinate and increase the risk of illness, odor and discolored water. But identifying correct chlorination levels is difficult to determine. Water quality can fluctuate quickly based on the number of swimmers and the sweat, dirt, oils, and sunscreen they introduce into the water, as well as the level of biological contaminants like insects and leaves. Even temperature plays a role, as some bacteria thrive at temperatures above 80-90°F.

In addition to continuously monitoring pH levels, measurement of Oxidation Reduction Potential (ORP), is one the most reliable and efficient ways to ensure the effectiveness of a sanitizer, such as chlorine, in pools and spas. ORP levels indicate effective chlorination concentration for killing off bacteria and preventing organism growth.

Both the S465 Series and S420 Sensor Series employ a ½” NPT connection for easy in line installation or use with existing Acu-Trol® or Strantrol® flow cells, without modification. The S465pH and ORP models are supplied with a BNR connector for quick connection to an aquatic controller, while the S420 models are available with the option of 30 inch or 10 foot cable lengths for easy integration into existing systems. Advanced signal shielding reduces noise for more accurate communication with process control systems.
