Handheld Water Quality Meter On-site Measurement Method for ORP and pH

Handheld Water Quality Meter is a portable water quality analyzer integrating ORP, pH, and temperature detection functions. The ORP measurement range is -2000 to 2000 mV, and the pH range is 0 to 14. It has a built-in 6000mAh lithium battery and is suitable for rapid on-site testing in industrial wastewater treatment, water disinfection effect monitoring, and aquaculture.

Handheld Water Quality Meter is a portable testing device suitable for industrial wastewater, aquaculture, river monitoring, swimming pools, and other fields. This instrument integrates oxidation-reduction potential (ORP), pH, and temperature measurement functions, meeting the needs of rapid on-site measurement in various water quality testing scenarios. The instrument adopts a handheld main unit design, with a built-in 6000mAh high-capacity rechargeable lithium battery, a rated power of 3W, and an external power supply of DC 5V/2A, supporting long-term outdoor operation.

Oxidation-reduction potential is one of the core measurement parameters of Handheld Water Quality Meter. ORP reflects the combined effects of all oxidants and reductants in water, making it a crucial comprehensive indicator of water quality. In industrial wastewater treatment, ORP measurement is used in redox systems, primarily for the reduction of chromic acid and the oxidation of cyanide. In water disinfection and application, ORP measures the disinfection effectiveness of swimming pool water, mineral water, and tap water—the bactericidal efficiency of E. coli in water is directly related to ORP, thus making it a reliable indicator of water quality. In aquaculture, ORP reflects the concentration of certain inorganic substances, the state of aquatic organisms, and the oxygen content in the water, demonstrating the macroscopic redox properties of the water and serving as a comprehensive indicator of water quality. This instrument's ORP measurement range is -2000mV to 2000mV, with a resolution of 0.1mV and an error range of ±10mV.

Handheld Water Quality Meter also supports on-site measurement of pH and temperature. The pH measurement range is 0 to 14pH, with a resolution of 0.1 and an error range of 0.05pH. The temperature measurement range is 5 to 60 degrees Celsius, with a resolution of 0.1 degrees Celsius and an error range of ±1 degree Celsius. The instrument employs electrode sensing technology, enabling instant response to water samples and significantly shortening the detection cycle. Some models are equipped with automatic temperature compensation to effectively mitigate the impact of ambient temperature fluctuations on electrochemical measurement results.

The Handheld Water Quality Meter user interface is simple and intuitive. Some products feature a smart operating system, supporting functions such as photo taking, screenshotting, 4G, WIFI, and satellite positioning. The instrument can be configured with a cloud monitoring platform, allowing for direct wireless transmission of test results for short-term and long-term water quality analysis. Data storage capacity can reach over 80,000 records, supporting multiple communication methods including Type-C, WIFI, hotspot, and Bluetooth. This instrument is suitable for various scenarios such as pure water plants, tap water plants, domestic sewage treatment plants, industrial wastewater, aquaculture, river monitoring, swimming pools, water source protection, production monitoring, and scientific research experiments.
