Handheld pH/DO Meter, IP67 Field Testing with Backlit LCD

Description

LAQUA PD210 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 dual-channel meter measures pH, ORP, dissolved oxygen, and temperature in one portable unit, making it suitable for environmental testing, laboratory use, education, and on-site water analysis. The backlit LCD, built-in electrode stand, and foldable meter stand support convenient day-to-day use, while the IP67 housing is waterproof, dustproof, shock-resistant, scratch-resistant, and non-slip for dependable use in demanding conditions.

The meter supports automatic pH calibration up to 5 points with USA and NIST buffers, or up to 6 points with DIN 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 testing. Built-in memory stores up to 500 data with auto log support, while auto stable, auto hold, and real-time modes improve workflow convenience. The handheld meter kit is supplied in a durable carry case complete with electrodes, 60 mL USA pH buffer solutions, operating manual, and 2 x AA alkaline batteries, making it a practical ready-to-use solution for portable water quality testing.
