Common questions about this category

Answers for buyers sourcing ph/ec/tds meters and solutions.

What meters do commercial growers need?
At minimum, reliable pH and EC (or TDS) meters at every mixing point, plus the calibration and storage solutions to keep probes accurate. For larger operations, inline monitoring adds continuous data, but handheld meters remain the backbone of batch verification.
How often should pH and EC meters be calibrated?
Calibrate on a regular schedule and whenever readings drift, using fresh buffer solutions. Probes are consumables that degrade with use, so budget for replacement and keep buffers and storage solution on hand to protect accuracy between calibrations.
What is the difference between EC and TDS?
Both estimate dissolved nutrients from conductivity. EC reports conductivity directly, while TDS converts it to an estimated solids figure using a factor that varies by meter. Pick one unit and standardize so your team reads feed strength consistently.
Why does pH matter for nutrient uptake?
pH controls which nutrients plants can absorb. Out-of-range pH locks out specific elements even when the feed is correct, showing up as deficiencies. Keep solution pH in your media's target band and verify it every batch with a calibrated meter.
