Handheld pH/ORP/Temperature Meter, IP67 Waterproof Field Testing with GLP Data Logging

Description

LAQUA PH220 pH, ORP and Temperature Handheld Meter is designed for routine water quality testing in the field, combining precise measurement with practical portability. This waterproof handheld meter measures pH, ORP, and temperature in one unit and features a backlit LCD, built-in electrode stand, and foldable meter stand for convenient use across laboratory, environmental, and on-site testing applications. Its IP67 housing is waterproof, dustproof, shock-resistant, scratch-resistant, and non-slip, making it suitable for demanding working conditions where reliable handheld performance matters.

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 0.01 pH resolution, offset and average slope display, ORP calibration option, and automatic or manual temperature compensation. For better data control, the PH220 includes a real-time clock and date and time stamp for GLP compliance, built-in memory for up to 1000 data, and auto log support. PC connection by USB cable and printer connection by RS232 cable also support data collection and printout workflows. For customer convenience, the handheld meter kit is supplied in a durable carry case complete with electrode, 60 mL solutions, operating manual, and 2 x AA alkaline batteries, with USA pH buffers included for this kit configuration.
