Hanna Instruments – HI98301 DiST 1 Waterproof TDS Tester with 0-2000 ppm Range

The HI98301 DiST 1 Waterproof TDS Tester is a compact, low-range total dissolved solids (TDS) meter designed to measure 0 to 2000 ppm (mg/L) with ±2% F.S. accuracy. It features automatic one-point calibration at 1382 ppm, automatic temperature compensation, and a durable graphite sensor that reduces polarization effects and resists oxidation. Built with a slim ergonomic design, waterproof floating casing, and Battery Error Prevention System (BEPS), this tester is ideal for water filtration, environmental monitoring, laboratory use, and educational applications.

  • Measures TDS from 0–2000 ppm with ±2% F.S. accuracy
  • Automatic one-point calibration at 1382 ppm
  • Waterproof floating design with ergonomic slim body
  • Graphite sensor with BEPS and battery level display

Description

The HI98301 DiST 1 TDS Tester is designed for accurate and reliable measurement of total dissolved solids in water up to 2000 ppm (mg/L). With automatic temperature compensation (0–50°C) and a fixed EC-to-TDS conversion factor of 0.5, it ensures consistent and precise readings across varying conditions. The graphite sensor minimizes polarization effects and does not oxidize, providing stable long-term performance.

Compact and user-friendly, the tester features a waterproof casing that floats if dropped, making it suitable for field use. The automatic one-point calibration at 1382 ppm simplifies operation, while the Battery Error Prevention System (BEPS) and battery percentage display at startup prevent inaccurate readings due to low power. Its slim, pocket-sized design makes it convenient for daily professional or laboratory use.

Features

  • TDS Measurement: 0–2000 ppm (mg/L) range with ±2% F.S. accuracy.
  • Automatic Calibration: One-point calibration at 1382 ppm with single-button operation.
  • Temperature Compensation: Automatic from 0–50°C (32–122°F) with 1.9%/°C coefficient.
  • Graphite Sensor: Reduces polarization effects and resists oxidation for stable readings.
  • Waterproof Floating Design: Durable casing that floats if dropped in water.
  • Slim Ergonomic Body: Comfortable handheld or pocket-sized tester.
  • Battery Error Prevention System (BEPS): Prevents low battery from affecting measurement accuracy.
  • Battery Indicator: Displays battery percentage at startup with auto shut-off (8 min, 60 min, or disabled).
  • Long Battery Life: CR2032 3V lithium battery provides approximately 250 hours of continuous use.
