Description:

Analog Electrical Conductivity Sensor/Meter V2 (K=1) 

DFRobot Gravity: analog electrical conductivity meter V2 is specially used to measure the electrical conductivity of an aqueous solution, and then to evaluate the water quality, which is often used in water culture, aquaculture, environmental water detection, and other fields.

Tips:

In order to ensure measurement accuracy, it is strongly recommended to add a temperature sensor to measure the temperature and achieve automatic temperature compensation. DS18B20 waterproof temperature sensor can also be used.

Attention:

1.The probe is a laboratory-grade probe. Do not immerse in liquid for a long time. Otherwise, this will shorten the life of the probe.

2.Platinum black layer is attached to the surface of the sheet metal in the probe. It should avoid any object touching it. It can only be washed with distilled water, otherwise, the platinum black layer will be damaged, resulting in an inaccurate measurement.

Features:

• 3.0~5.0V wide voltage input
• Hardware filtered output signal, low jitter
• AC excitation source, effectively reduce polarization
• Gravity connector and BNC connector, plug and play, no welding
• Software library supports two-point calibration and automatically identifies standard buffer solution, integrates temperature compensation algorithm
• Uniform size and connector, convenient for the design of mechanical structures

Applications:

• Water quality monitoring
• Aquaculture
• Hydroponic & Aquaponic
