Buying Guide

Parameters covered

Choose a meter that directly measures the analytes you need — common combinations include pH, TDS/EC/salinity, ORP, and free chlorine

Sensor accuracy and range

Check the stated accuracy and operational range for each parameter; lab-style tasks require tighter accuracy than general pool or tap-water checks

Calibration and maintenance

Prefer meters that support manual or automatic calibration and provide guidance on calibration solutions and electrode care to maintain long-term accuracy

Form factor and durability

Handheld pen-style devices are portable for field use, while rugged or splash-resistant housings improve durability around pools and labs

Battery life and power

Consider run time and common battery types; replaceable batteries are convenient for remote testing whereas rechargeable units reduce recurring costs
