Product Overview

Comprehensive kit which allows you to measure the electrical conductivity of aqueous solutions and evaluate water quality. With a plug-and-play design, intuitive software library and support for 3.3V/5V microcontrollers (such as Arduino) it can be a simple and effective measuring solution. The software library uses a two-point calibration method, temperature compensation algorithm and can automatically identify standard buffer solution.
  • 3V-5V Wide voltage input range and support for both 5V and 3.3V control boards
  • Hardware based filter for the output signal reduces jitter
  • Reduced polarisation to improve precision and prolong probe lifespan
  • Plug and play Gravity 3-pin interface and BNC probe connector for convenience, no soldering required
  • Board output voltage: 0-3.4V
  • Measurement Accuracy: ±5%
  • Board size: 42x32mm
  • Laboratory Grade probe
  • Probe cell constant: 1.0
  • Probe Detection Range: 0-20ms/cm
  • Recommended Detection Range: 1-15ms/cm
  • Temperature Range: 0-40°C
  • Probe Life: Approx. >0.5 year (depending on frequency of use)
  • Probe cable length: 1m
