Handheld Dissolved Oxygen Meter, IP67 Waterproof Field Testing with GLP Data Logging

Description

LAQUA DO220 Dissolved Oxygen and Temperature Handheld Meter is designed for routine water quality testing in the field, combining portable dissolved oxygen measurement with practical handheld operation. This waterproof handheld meter measures dissolved oxygen in ppm, mg/L, and percent saturation, while also displaying temperature for broader testing convenience. The backlit LCD, built-in electrode stand, and foldable meter stand support efficient day-to-day use, while the IP67 housing is waterproof, dustproof, shock-resistant, scratch-resistant, and non-slip for dependable use in demanding field conditions.

The meter is built for reliable dissolved oxygen testing with salinity, temperature, and barometric pressure compensation, together with up to 2 calibration points using a galvanic DO electrode. Real-time clock and date and time stamp functions support GLP-style record handling, while built-in memory stores up to 500 data with 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 galvanic electrode, operating manual, and 2 x AA alkaline batteries. As a DO-only kit, 60 mL solutions are not included in this configuration.
