What is the primary function of a combined pH and Conductivity Meter?

Its primary function is to simultaneously measure the pH level and electrical conductivity of liquid samples, providing comprehensive water quality data.

Can this type of meter be used for ultra-pure water applications?

Yes, many advanced models include specific functions and temperature compensation algorithms designed for accurate readings in ultra-pure water.

What is Total Dissolved Solids (TDS) measurement?

TDS measurement estimates the total concentration of dissolved substances in water, typically derived from conductivity readings using an adjustable conversion factor.

Are probes included with used units?

Probes (pH electrode, conductivity cell, temperature probe) are essential for operation. While often included, buyers should confirm their presence and condition with the seller.

What maintenance is typically required for these meters?

Regular calibration of pH and conductivity channels, proper storage and cleaning of electrodes, and occasional battery replacement (if applicable) are common maintenance tasks.
