Frequently Asked Questions

What is the difference between pH and ORP measurement?

pH measures the acidity or alkalinity of a solution on a scale from 0 to 14. ORP (Oxidation-Reduction Potential) measures the tendency of a solution to gain or lose electrons, indicating its oxidizing or reducing capacity, typically measured in millivolts.

Do your sensors require regular calibration?

While all electrochemical sensors benefit from periodic calibration, our digital sensors with built-in diagnostics and temperature compensation require less frequent calibration than analog counterparts. Many optical sensors (like DO) require no calibration at all.

Can I connect multiple sensors to one controller?

Yes, our Multi-Parameter Controllers (like the MCC200-A8) support 1-8 digital sensors simultaneously, including pH, ORP, conductivity, dissolved oxygen, turbidity, and more, all communicating via RS485 Modbus.

What is the typical lifespan of your pH sensors?

With proper maintenance and storage, our industrial pH sensors typically last 1-2 years in continuous operation. Digital sensors with advanced diagnostics provide early warnings for membrane replacement or cleaning.
