Compact pH Meter EZL-PM311

EziLab offers the Compact pH Meter EZL-PM311, a portable digital pH meter that reads from -2 to 19.99 pH with millivolt readout in a 360 g body measuring 160 by 90 by 30 mm. An IP57 rugged, skid-proof shell and two AA batteries make it fit for field work, while a white-backlit LCD stays readable outdoors. A microprocessor handles auto calibration, auto temperature compensation, auto shutoff, self-diagnosis, and low-battery warning, and memory stores up to 200 result sets. The kit ships with a pH electrode, temperature probe, spare batteries, and 50 ml bottles of 4.00, 6.86, and 9.18 buffers. Automatic temperature compensation corrects readings as samples warm or cool between sites, and stored results let technicians log readings now and review them later. The meter also handles high-purity water and ammonia-dosed water, where basic testers struggle. Food and beverage plants track acidification in fermented foods, brines, and canned vegetables, while craft breweries monitor mash and wort. Growers test soil and hydroponic nutrient feeds, and machine shops check cutting oils and alkaline wash baths. Water utilities and QC labs carry this handheld pH meter for quick field checks.
