Handheld pH/ORP/Dissolved Oxygen Meter, IP67 Field Testing with GLP Data Logging

Description

LAQUA PD220 pH, ORP, Dissolved Oxygen and Temperature Handheld Meter is designed for routine water quality testing in the field, combining multi-parameter performance with practical handheld operation. This waterproof standard handheld meter measures pH, ORP, dissolved oxygen, and temperature in one portable unit, making it suitable for environmental monitoring, laboratory use, education, and on-site water analysis. The backlit LCD, built-in electrode stand, and foldable meter stand support efficient daily use, while the IP67 casing is waterproof, dustproof, shock-resistant, scratch-resistant, and non-slip for dependable performance in demanding conditions.

The meter supports automatic pH calibration up to 5 points with USA and NIST pH buffers, or up to 6 points with DIN pH buffers, together with ORP calibration, automatic or manual temperature compensation, and offset and average slope display. Dissolved oxygen measurement is available in ppm, mg/L, and percent saturation, with salinity, temperature, and barometric pressure compensation for more controlled DO testing. Real-time clock and date and time stamp functions support GLP-style record handling, while built-in memory stores up to 1000 data with auto log support. For customer-ready use, the handheld meter kit is supplied in a durable carry case complete with electrodes, 60 mL solutions, operating manual, and 2 x AA alkaline batteries, with USA pH buffers included for this kit configuration.
