The HI98309 utilizes a conductometric method to assess water purity, making it perfect for applications in the electronics and semiconductor industries. Encased in durable housing, this tester ensures reliable performance even in harsh industrial environments.
Equipped with an amperometric graphite electrode, the HI98309 guarantees superior repeatability in measurements as it prevents oxidation. Its amperometric measurement of EC is based on Ohm’s Law (I = V/R), where R relies on the distance between two pins and their surface area. The non-oxidizing graphite pins provide an optimal surface, ensuring accurate and dependable results. Calibration is a breeze — simply immerse the electrode tip into the calibration solution and adjust the trimmer located on the side of the tester.
Conductivity and resistivity are normalized terms used to denote a substance’s bulk intrinsic property.
Key Features:
- Pre-calibrated: Arrives factory-calibrated with freshly prepared low-conductivity solutions
