Part Number: DFR0300
Description: Analog Electrical Conductivity Sensor / Meter V2 (K=1)
INTRODUCTION
DF Robot Gravity: analog electrical conductivity meter V2 is specially used to measure
the electrical conductivity of aqueous solution, and then to evaluate the water quality,
which is often used in water culture, aquaculture, environmental water detection and
other fields.
This product, as an upgraded version of electrical conductivity meter V1, greatly
improves the user experience and data precision. It supports 3~5v wide voltage input,
and is compatible with 5V and 3.3V main control board; The output signal filtered by
hardware has low jitters; The excitation source adopts AC signal, which effectively
reduces the polarization effect, improves the precision and prolongs the life of the
probe; The software library uses two-point calibration method, and can automatically
identify standard buffer solution, so simple and convenient.
With this product, main control board (such as Arduino) and the software library, you
can quickly build an electrical conductivity meter, plug and play, no welding. DF Robot
provides a variety of water quality sensor products, uniform size and interface, not only
meet the needs of various water quality testing, but also suitable for the DIY of multiparameter water quality tester.
Conductivity is the reciprocal of the resistance, which is related to the ability of the
material to carry the current. In the liquid, the reciprocal of the resistance, the
conductivity, is the measure of its ability to conduct electricity. Conductivity is an
important parameter of water quality. It can reflect the extent of electrolytes present in
water.
Tips:
In order to ensure the 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 inaccurate measurement.
