Buying Guide

Parameters you need

Choose a meter that measures the specific analytes you use most often—pH, TDS/EC, salinity, chlorine and temperature are common in this price class

Calibration and accuracy

Prefer meters that support multi-point calibration and report accuracy or resolution for each parameter to ensure reliable lab data

Sensor and probe quality

Look for replaceable or protected probes and clear guidance on probe storage to extend lifespan and keep readings stable

User interface and logging

Simple menus, hold/auto-stabilize functions, and any data-hold or averaging features improve repeatability when testing multiple samples

Build and portability

Assess housing durability, splash resistance, and battery type for field use; compact units are useful for pool and on-site testing
