Descriptions: The KL-98102 is an ideal pocket tester for educational purposes. Designed with a 0.01 pH resolution and one-point manual calibration through easy-to reach trimmers, it immediately displays pH variations to reflect the smallest change in the sample. With only two operation buttons, it allows immediate and precise response in a concise design. This is a rugged unit that can be used again and again. The probe is even durable enough to be used as a stirrer. The HOLD button will freeze the display reading for your documentation requirements.

Descriptions: •Renewable junction •Easy 1 point manual calibration •Simple to use •Economical The Champ revolutionized the pH industry by providing non-technical personnel with a simple, inexpensive solution to accurate pH measurement. PH 98081 is used by millions of people around the world to monitor pH in laboratories and industrial applications as well as in agriculture, fish farming, food manufacturing and quality control, swimming pools and the printing industry. With a renewable cloth junction, the Champ has an extended life over typical pH testers. A normal junction clogs with use over time and a typical tester would normally have to be thrown away once the junction is too contaminated. PH 98081’s junction is 2 cm long and when dirty, can be pulled out to expose a fresh section to effectively renew the Champ’s life. Calibration is performed manually at 1 point with a trimmer located on the side of the tester. Specifications: Mea , suring range 0.00~14.00PH Accuracy
