  • Comprehensive Multi - Parameter Detection: Our multifunctional water quality detection pen offers an outstanding feature of simultaneously measuring multiple water quality indicators. Not only can it measure TDS, temperature (in both degree centigrade and fahrenheit), and EC like the 4-in-1 digital water tester, but it also caters to a broader range of needs.
  • High - Precision and Reliable Sensing: Equipped with high-sensitivity sensors, this water quality pen ensures accurate and reliable measurement data. Similar to the TDS meter with its high-sensitive probe for quick and convenient TDS testing, our pen's sensors enable precise detection across various water quality aspects.
  • Rapid Response for Enhanced Efficiency: The detection speed of our water quality pen is impressively fast. In most cases, it can display results within just a few seconds, much like the quick results provided by the digital water tester.
  • Portable and Compact Design for Versatile Use: With a compact and lightweight design, our water quality pen is extremely easy to carry. It's perfect for outdoor water source detection, such as when exploring natural water sources during hikes or camping trips. At the same time, its portability makes it a convenient tool for daily household use, allowing you to quickly test the quality of your tap water, fish tank water, or other water sources around your home.
  • Broad Applicability to Meet Diverse Needs: Our water quality pen is suitable for a vast array of scenarios. It can be used for testing drinking water, fish tank water, swimming pool water, and even farmland irrigation water, just like the digital water tester's application in drinking water, aquariums, and hydroponics. This wide range of applications makes it a versatile and essential tool for anyone concerned about water quality, whether it's for health, environmental, or other purposes.
