Gravity Industrial Analog Electrical Conductivity Meter Kit for Water Quality Monitoring K1 IP68

Conductivity is the reciprocal of an object's resistivity. It represents a material’s ability to pass a current. In a liquid, conductivity is a measure of a solution’s ability to conduct electricity and can reflect the amount of dissolved or salinity of a water source, so it’s an important parameter in water quality monitoring.

IR Beam Interruption Sensor - LED 3mm - 0-50 cm

1 review

The sensor reacts to an interruption in the beam of infrared light that is transmitted between the transmitter and receiver. When the beam is interrupted by another object, the receiver signals this event by lighting up. The module is equipped with a 3 mm IR LED with an illumination angle of 10°. Beam interruption systems are used e.g. in measuring gates.
