Key Features

• Four EC Measurement Ranges
  Measures conductivity across four automatic ranges:

  • 0.0 to 199.9 µS/cm

  • 0 to 1999 µS/cm

  • 0.00 to 19.99 mS/cm

  • 0.0 to 199.9 mS/cm
    Suitable for ultrapure water, drinking water, wastewater, and industrial solutions.

• Automatic Temperature Compensation (ATC)
  Built-in temperature sensor ensures accurate readings by adjusting for temperature variations from 0 to 50°C (32 to 122°F), with adjustable β coefficient (0 to 2.5%/°C).

• Manual One-Point Calibration
  Easy calibration via a front-panel knob allows precise adjustment for accurate readings across all ranges.

• Durable, Portable Design
  Compact and ergonomically shaped for use in the field or laboratory. Withstands humidity up to 95% and operates in temperatures from 0 to 50°C.

• Long Battery Life
  Powered by a 9V battery, delivering approximately 100 hours of continuous use—ideal for long fieldwork sessions.

• High-Quality EC Probe Included
  Comes with the HI76302W 2-pin conductivity probe, featuring an internal temperature sensor, a DIN connector, and a 1-meter (3.3 ft) cable for convenience and accuracy.
