Description

Grove – ORP Sensor Kit (HR-O) aims to measure the cleanliness of the water and its ability to break down contaminants. It works with a 5 meters IP68 ORP probe, offering a -2000mV to 2000mV sensing range, operating under 0-80℃ which is a member of the simple-to-use Grove ecosystem and supports Arduino programming. The sensor is environmentally friendly and RoHS certificated.

An ORP Sensor measures the activity of oxidizers and reducers in an aqueous solution, it measures the ability of a lake or river to cleanse itself or break down waste products. Different oxidation-reduction processes and conditions have different ORP values(mV), with aerobic conditions having higher ORP values and anaerobic conditions having lower ORP values. In common conditions like spas, it is widely acknowledged that the safe values are between 650 mV and 750 mV.

For more anaerobic and aerobic environments detection, you will find this sensor amazed that it offers an even wider range measurement and the value of which is from -2000 mV to +2000 mV. It also provides ±15mV sensing accuracy when it operates at 0-60°C.

With such performance, its assembly, operation, and value-read are pretty simple. Being a member of the Grove ecosystem and supported by Arduino, you can easily connect it to any Arduino-support board with a Grove cable and simply read the output ORP value.

Note

If you find white solid granular crystals around the probe shroud after receiving the product, this is normal and please do not worry. It is caused by temperature change, environmental change or redox during the process of delivery. However, it will not affect the nature of the internal potassium chloride solution and the normal operation of the sensor.

If you find it, please use a wet paper towel to gently wipe off the crystals on it, please do not let it near your children to avoid accidental ingestion.

Flow measurement is the quantification of bulk fluid movement. Flow can be measured in a variety of ways. The common types of flowmeters with industrial applications are l Obstruction type (differential pressure or variable area), Inferential (turbine type), Electromagnetic, Fluid dynamic (vortex shedding), Anemometer, Ultrasonic, Mass flowmeter

Flow measurement methods other than positive-displacement flowmeters rely on forces produced by the flowing stream as it overcomes a known constriction, to indirectly calculate flow. Flow may be measured by measuring the velocity of fluid over a known area. For very large flows, tracer methods may be used to deduce the flow rate from the change in concentration of a dye or radioisotope.
