This 7-in-1 water quality testing pen unlocks 7 core indicators with a single click, eliminating the need for a professional laboratory. It comprehensively covers seven key indicators: pH, ORP (oxidation-reduction potential), TDS (total dissolved solids), EC (exchange coefficient), salinity, resistivity, and water temperature. From acidity and alkalinity to pollutant content, from water activity to physical state, each indicator is directly related to water safety and user experience.

Whether it's household drinking water, aquarium water, coffee brewing water, hydroponic nutrient solution, or even water from a water purifier or swimming pool, it displays stable data after being submerged in water for just 3 seconds. With its IP67 waterproof design and one-button operation, no professional knowledge is required; even the elderly and children can easily use it, ensuring you know exactly what you're using.

Are you still worried about the unknown water quality affecting your health, farming or planting? This 7-in-1 water quality detector combines 7 core indicators such as pH, ORP, EC, TDS, salinity (S.G), and temperature (℃/℉) into one. It is an all-round water quality "master" for scenarios like household water use, aquaculture, gardening, and industrial water use, allowing you to precisely control the water quality and feel at ease without worries.
It adopts a pen-style portable design, allowing you to operate it handheld. You can switch 7 parameters at once, without any complex steps, and quickly obtain water quality data. Whether it's detecting the acidity and alkalinity (pH) of household drinking water, the purity (TDS, EC), the salinity in aquaculture, the oxidation-reduction potential (ORP) in aquaculture, or the conductivity of gardening irrigation water, it can accurately present the values, like equipping the water quality with a "multi-dimensional health check instrument", making each water quality indicator clearly visible.
Equipped with a high-definition digital display screen, the data is read clearly and intuitively. Even in strong outdoor light, it can be easily viewed. It also has an automatic temperature compensation function to ensure the accuracy of detection under different water temperatures; the salinity detection supports precise measurement in different scenarios such as seawater and freshwater, meeting the full-cycle water quality management needs of aquaculture from breeding to maturity.
In terms of operation, it is simple to calibrate, equipped with standard calibration liquid, and only needs to follow the instructions to complete the calibration to ensure long-term detection accuracy; the waterproof design of the body allows it to be directly immersed in water for detection, making the usage scenarios more flexible.
For household users, it is the "gatekeeper" for drinking water safety, allowing you to always know if the water quality meets standards; for aquaculture farmers, it is the "key assistant" for successful farming, by precisely regulating water quality, reducing fish and shrimp diseases, and increasing farming profits; for gardening enthusiasts, it is the "nutritionist" for plant health, adjusting the irrigation water based on EC, pH, etc., making the plants and fruits grow better. With this 7-in-1 water quality detector, it is like having the "golden key" to water quality management, making every hidden danger on the water surface disappear, protecting your health, farming, and planting, and opening a new experience of precise water quality management.
