Handheld online conductivity detector

【Handheld online conductivity detectorFunction Overview:

Industrial pH transmitter is a device for measuring the pH value (hydrogen ion concentration index, acidity and alkalinity) of a solution, with automatic temperature compensation function, and can switch between automatic and manual temperature compensation at will.

The optical detection method of the dissolved oxygen measurement probe for water quality can effectively measure the molecular oxygen dissolved in water and eliminate the interference of pH fluctuations, ammonia nitrogen and other chemicals or heavy metals in the water, thereby providing more stable and accurate measurement results over a longer period of time.

The water quality conductivity is a device used to measure the conductivity value of a solution, which has an automatic temperature compensation function and can compensate the current temperature conductivity to a specified temperature.

Basic conventional water quality monitoring digital turbidity transmitter with built-in temperature transmitter, capable of automatic temperature compensation, suitable for long-term online monitoring environments.

This product is suitable for continuous monitoring of cross-sectional water quality, aquaculture, sewage treatment, environmental protection, pharmaceuticals, food and tap water solutions, industrial wastewater, domestic wastewater, agriculture, aquaculture industries, and other scenarios.

【Handheld online conductivity detectorDetection principle: The reference solution inside the electrode glass bubble is affected by the pH of the measured solution, causing the electrode to generate an electromotive force (voltage), and the magnitude of the electromotive force reflects the pH of the measured solution. Dissolved oxygen is measured using fluorescence method, which does not consume oxygen and does not require electrolyte. The measured value of solution conductivity is calculated based on the resistance presented by the electrode and the constant K of the electrode itself, and obtained through temperature compensation. Adopting the mature 90 ° scattered light principle from abroad, using the design method of infrared LED light source and fiber optic transmission optical path; At the same time, an internal filtering algorithm is added, which has strong resistance to external light interference.
