Water Quality Instruments FAQs
What is the difference between TDS and conductivity?
Conductivity measures how well water conducts electricity, while TDS is usually an estimated value calculated from conductivity. Both are commonly used to assess dissolved salts in water treatment applications.
When do I need a pH meter?
A pH meter is useful when checking acidity or alkalinity, adjusting chemical dosing, commissioning treatment systems or monitoring process water conditions. Calibration is important for reliable readings.
What is ORP used for?
ORP is commonly used as an indicator for oxidation-reduction conditions, often in chlorination, disinfection or process control applications. It should be interpreted together with the specific treatment process.
Do handheld meters need calibration?
Yes. Handheld pH, conductivity and ORP meters usually require regular calibration using suitable calibration solutions. Calibration frequency depends on usage, accuracy requirements and storage conditions.
Can instruments be used for system control?
Some instruments are designed only for manual testing, while others can be connected to controllers, dosing pumps or monitoring systems. Check the signal output, installation type and control requirements before selection.
