Gravity Analogue Electrical Conductivity Sensor - DFR0300

The DFR0300 from DFRobot is a 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. Typical applications include water quality monitoring, aquaculture as well as hydroponics & aquaponics.

• 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. <gt/>0.5 year (depending on frequency of use)
• Probe cable length: 1m
