Apera PH8500-DP . Portable pH Meter Kit

Developed for professional pH measurement of dairy products (milk, yogurt, cream, yogurt, etc.) and other liquid foods (jams, BBQ sauces, etc.) using the LabSen 823 pH/Temperature electrode. Also suitable for general aqueous solutions.

GLP data collection and management

amount. Or manually record data via GLP data management (500 groups of data storage) and USB data output for further analysis and reporting.

Easy to calibrate

Quick and easy car from 1 to 3 points. pH calibration, setting pH standards 1.68, 4.00, 7.00, 10.01, 12.45. Self-diagnosis ensures that pH calibration occurs

LabSen 823 pH/electrode temperature

LabSen is equipped with special sensor technology and high quality materials from Switzerland, with pH/temperature 823. This electrode is suitable for professional pH measurement of milk, cream, yogurt, sauces, jams, soups and other liquids containing protein.

special electrolyte

Apera Blue Gel does not work at all, which means that it never ulcers. The bar also works well upside down. It is not only more convenient to use, but also improves the measurement accuracy by eliminating the heat load in the inner glass film.

The external electrolyte used for the electrodes, Protelyte, consists of a solution containing proteins to prevent the conductions from clogging.

Swiss patented pH/Temperature formula structure

Compared with traditional built-in thermistors, the temperature response time is increased by 40%, which speeds up the ATC and installation process.

Silver ion trap reference system

Combination of a long range reference system and a silver ion trap. Silver ion trap absorbs all extruded Ag+ and ensures no Ag+ in the reference electrolyte, avoiding junction blockages caused by samples containing sulfides, proteins or TRIS solution.

Data logger with USB output

amount. Or manually record data via GLP data management (500 groups of data storage) and USB data output for further analysis and reporting.

Everything is contained in a sturdy carrying case

All necessary solutions and accessories are included in a sturdy carrying case, including 3 bottles of pH calibration solution (4/7/10), soaking solution, etc.

strong and durable

The IP57 waterproof construction makes this gauge ideal for use in harsh environments. The rubber casing protects the device from general shock and gives you a secure grip.
