Introduction
Product Definition
Blue Ink Test Reagent is a specialized reagent used for rapid detection of the integrity of RO reverse osmosis membranes and ultrafiltration membranes. By adding a small amount of Blue Ink Test Reagent to the water sample to be tested or to the piping of water purification equipment, you can determine whether membrane elements are damaged or leaking based on whether the water sample changes color. The product uses a semi-quantitative analysis method, reacts quickly, and is suitable for the installation, maintenance, troubleshooting, and performance verification of water purification equipment.
Product Features
- Rapid detection: results can be observed in about 5 seconds, allowing immediate judgment of membrane condition.
- Easy operation: dropper bottle design allows direct dropwise addition, with no complex steps or auxiliary equipment required.
- Semi-quantitative analysis: intuitive discrimination through color change, simple and clear.

FAQ
Q: How does Blue Ink Test Reagent detect whether an RO membrane is damaged?
A: Add an appropriate amount of Blue Ink Test Reagent to the RO membrane feed water side or raw water side. If blue appears on the permeate side, it indicates that the RO membrane is damaged or leaking.
Q: What are the requirements for the water sample during testing?
A: The water sample to be tested should be clear and transparent. Turbid water samples may affect color observation and judgment.
Q: How long does the reaction take?
A: A color change can usually be observed within about 5 seconds.
Q: How many times can one bottle be used?
A: Each bottle contains about 200 drops. The exact number of uses depends on the number of drops used for each test. Generally, a few drops are enough to complete each test.
Q: How should the reagent be stored?
A: It is recommended to store it at a temperature of 0-50℃ and humidity ≤85%RH, and use it within the 1-year shelf life.
