Frequently Asked Questions
What is the difference between TDS and EC?
TDS stands for Total Dissolved Solids and measures the amount of dissolved materials in water. EC measures Electrical Conductivity which relates to how well water conducts electricity. Higher TDS usually means higher EC and vice versa.
How often should I calibrate my meter?
Calibration should be done at least once a month for frequent users. If you use the meter less often, calibrate before each major session. Proper calibration ensures your readings remain accurate.
Can I use these meters for pH testing?
Not all meters support pH testing. You need a specific meter with pH electrodes. Check the product specifications to confirm it includes pH measurement capabilities.
Why do readings fluctuate in water?
Fluctuations may result from water temperature changes or uneven mixing. Use automatic temperature compensation if available. Stir the water gently and wait for stabilization.
Is a titanium probe better?
Titanium alloy probes are more durable and corrosion-resistant than standard ones. They last longer in varied water conditions. This makes them preferable for frequent testing.
Do these meters require batteries?
Yes most digital meters run on AAA or AA batteries. Check the battery life specifications. Replace them promptly when low indicators appear.
How do I clean the probe?
Rinse the probe with distilled water after each use. Avoid harsh chemicals that might damage the electrode. Store it in the protective cap to prevent drying.
Are these meters waterproof?
Some models are waterproof while others are water-resistant. Check the IP rating for protection levels. Waterproof designs are better for pool or hydroponic use.
