Buying Guide

Which parameters matter

Prioritize meters that measure the parameters you need (pH, TDS/EC, salinity, chlorine) rather than a long feature list with low accuracy

Sensor type and calibration

Look for devices with replaceable probes or one-point/two-point calibration to maintain accuracy over time

Readout and units

Choose a clear digital display and units you use (ppm for TDS, µS/cm for EC) to avoid conversion errors in the field

Build and water resistance

Select meters with durable housings and splash resistance if you’ll test pools or outdoor sources frequently

Battery and portability

Check battery type and size plus form factor so the meter suits field use and won’t need frequent battery changes

Value score vs. price

Compare value score and core features instead of only price; a slightly higher value score can mean longer-term reliability
