EziLab’s Automatic Potentiometric Titrator EZL-APT51 covers pH 0.00 to 14.00 and mV from -1800 to 1800 at 0.01 pH resolution, using a 10 mL burette with 1/10000 resolution and charging in roughly 55 seconds per full fill. An LCD display, multiple titration modes, and a smart guide system walk operators through setup, while USB or RS-232 computer control exports titration curves for reporting. Temperature compensation from -5C to 105C keeps endpoint detection stable across sample temperatures, and the included platinum, silver, pH, and reference electrodes cover common titration types out of the box. As a pH titrator built for potentiometric endpoint detection, this unit suits labs running acid-base, redox, and precipitation titrations on one shared instrument. Pharmaceutical laboratories use it for assay and content uniformity testing, while food and beverage QC teams rely on the same automatic titrator for acidity and salt content checks. Environmental monitoring programs apply it to water hardness testing, and chemical labs use the wide mV range for redox titrations too. Cosmetics manufacturers running raw material QC keep an automatic titration system like this one to replace manual burette work. Titration modes and burette size drive daily throughput, so see how this unit ranks on the Petroleum Testing Equipment and Automatic Potentiometric Titrator pages.
