Handheld Conductivity/TDS/Salinity Meter, IP67 Waterproof Field Testing with GLP Data Logging

Description

LAQUA EC220 Conductivity, Resistivity, Salinity, TDS 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 supports conductivity, resistivity, salinity, total dissolved solids, and temperature measurement in one portable unit, making it suitable for laboratory, environmental, process, and on-site testing applications. The backlit LCD, built-in electrode stand, and foldable meter stand support convenient day-to-day use, while the IP67 casing is waterproof, dustproof, shock-resistant, scratch-resistant, and non-slip for dependable use in demanding environments.

The EC220 is built for flexible conductivity-based testing with automatic calibration up to 4 points and manual calibration up to 5 points, together with adjustable reference temperature, adjustable temperature coefficient, selectable measurement unit, and adjustable cell constant. It also supports conductivity to TDS conversion, four TDS calibration curves, and two salinity curves for broader application coverage. For better record management, the meter includes a real-time clock, 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.
