Buying Guide

Parameters and probe compatibility

Choose meters that measure the specific parameters you need (pH, EC, TDS, salinity, chlorine) and confirm probes or sensors are replaceable and compatible with lab calibration solutions

Accuracy and calibration

Look for meters with stated accuracy specs and multi-point calibration support to maintain reliable readings for lab or regulatory work

Build and ingress protection

Waterproof housings and robust pocket or handheld designs are beneficial for field or pool testing; check the device rating for splash or immersion resistance

Data handling and connectivity

Consider whether the meter supports data logging, PC connectivity, or export (via USB/Bluetooth) when you need traceable records or integration with lab software

Consumables and maintenance

Factor in availability of replacement electrodes, calibration solutions and recommended maintenance intervals to keep long-term operating costs and downtime low
