HORIBA LAQUA PD220 | GLP pH, ORP, Dissolved Oxygen & Temperature Meter

The HORIBA LAQUA PD220 Handheld pH and Dissolved Oxygen Meter is designed for water-quality professionals who require combined measurements with traceable records. It measures pH, ORP, dissolved oxygen and temperature, making it suitable for regulated laboratories, wastewater facilities, aquaculture operations, environmental surveys and industrial monitoring programmes.

Its pH measurement range is -2.00 to 16.00 with 0.01 resolution and ±0.01 accuracy, while ORP readings extend to ±2000 mV. The dissolved oxygen channel measures 0.0 to 20.00 mg/L and 0.0 to 200.0% saturation with a galvanic probe that includes an integrated temperature sensor. Salinity and barometric-pressure compensation improve consistency under changing sample conditions. A backlit display, diagnostic messages, and Auto Stable, Auto Hold and Real-Time modes simplify routine field and laboratory work.

Data Tip: Use the real-time clock and date-stamped records to identify each sample by location, batch or process stage before transfer. The PD220 stores up to 1,000 readings and supports optional computer and printer communication for GLP documentation. Buy HORIBA LAQUA PD220 from Kamadi Pakistan for accurate multi-parameter analysis, competitive pricing and professional after-sales support.
