Product Description

The Hanna HI98129 is a handheld, waterproof tester designed for fast and accurate measurement of pH, EC/TDS, and temperature in a single compact device. Its integrated sensors and user-friendly features eliminate the need for multiple meters, making routine measurements efficient and reliable.

The HI98129 combines a high-accuracy pH electrode with a low-range EC/TDS sensor capable of measuring 0 to 3999 µS/cm (EC) and 0 to 2000 ppm (TDS). Temperature readings are also provided simultaneously, ensuring comprehensive monitoring of solution conditions. This multi-parameter approach reduces handling errors and streamlines laboratory or field workflows.

Housed in a lightweight, waterproof casing, the tester is designed for durability and ease of use in a variety of environments. Its graphite sensor minimizes polarization effects and resists oxidation, providing consistent, reproducible readings. The built-in Battery Error Prevention System (BEPS) safeguards against inaccurate measurements caused by low battery levels, while the automatic shut-off with three user-controlled settings conserves energy.

  • Handheld, waterproof meter for pH, EC/TDS meter and temperature measurements.
  • High-accuracy pH measurement and low-range EC/TDS (0–3999 µS/cm EC / 0–2000 ppm TDS).
  • Graphite sensor reduces polarization and resists oxidation for reliable readings.
  • HOLD button for easy measurement recording.
  • Battery Error Prevention System (BEPS) prevents low-battery errors.
  • Automatic shut-off with three user-controlled settings for energy efficiency.

Ideal for laboratory, environmental, agricultural, and industrial applications, the HI98129 ensures fast, accurate, and reproducible measurements in both field and bench settings.
