Hanna HI98309 UPW Ultra Pure Water EC Test

The Hanna HI98309 UPW Ultra Pure Water EC Test is a high-precision electrical conductivity (EC) tester specifically designed for ultra-pure water applications, where even the smallest ionic contamination matters. This compact and rugged device is ideal for environments such as semiconductor fabrication, electronics manufacturing, laboratory research, and pharmaceutical water validation. Thanks to its durable casing and sensitive graphite electrode, it offers fast, stable, and accurate EC measurements, even in harsh industrial conditions.

Features

• Designed for Ultra-Pure Water Measurement
  The HI98309 measures very low conductivity levels down to 0.001 µS/cm, allowing users to monitor water purity with exceptional sensitivity. As a result, it is perfectly suited for applications requiring the highest water quality standards.

• Factory Pre-Calibrated
  This device comes pre-calibrated using freshly prepared low-conductivity standard solutions, reducing setup time and ensuring immediate accuracy. Therefore, it can be used straight out of the box.

• Graphite Electrode Technology
  Unlike conventional metal electrodes, the graphite sensor minimizes polarization effects, thereby improving measurement stability and extending electrode life.

• Fast Temperature Response
  Equipped with automatic temperature compensation from 0 to 50°C, the tester delivers reliable results even as sample temperature fluctuates. In addition, this enhances usability in dynamic environments.

• Amperometric Measurement Principle
  Based on Ohm’s Law (I = V/R), the tester uses the electrical current response to determine conductivity. Consequently, it delivers results consistent with industrial EC measurement standards.

• Lightweight and Rugged Design
  Housed in a compact body weighing just 95 g, the HI98309 is ideal for both laboratory benchtops and field testing. Moreover, its sealed design protects it from dust and moisture exposure in tough settings.
