HORIBA LAQUA PD220 Waterproof Handheld pH/ORP/Dissolved Oxygen/Temperature Meter
Description
HORIBA LAQUA PD220 Waterproof Handheld pH/ORP/Dissolved Oxygen/Temperature Meter
Product Overview
The HORIBA LAQUA PD220 is a professional dual-channel handheld water-quality meter for measuring pH, ORP, dissolved oxygen (DO) and temperature. It combines pH/ORP measurement with dissolved oxygen testing in a rugged, portable IP67 waterproof instrument for laboratory and field applications.
The meter supports automatic pH calibration, ORP calibration, DO calibration, automatic compensation functions and data logging. Its backlit display, integrated electrode holder and durable carrying case support convenient routine testing in water monitoring, aquaculture, research and process applications.
