easy to carry Negative ion tester portable 1 PCS Air Ion Tester ion source measure Air Ion Meter for Negative Air Ion Generator

Product Information

Sulfate ions in solution produce a white precipitate with barium chloride solution in the presence of dilute hydrochloric acid. Silver ions react with halide close halide A halide ion is an ion formed when a halogen atom (an atom from group 7) gains one electron.

Besides negative oxygen ion detection, measurement elements such as temperature, humidity, formaldehyde, pm2. External wind, with wind guard in place, up to 15 km/hr (9 mph) in any direction will maintain accuracy to within +/- 25%. You can change your choices at any time by visiting Cookie preferences, as described in the Cookie notice. a variety of powder anion testing, such as natural ore, anion powder, tourmaline (tomalin), meteorites and other anion content testing and evaluation.

Ne ion test kits are commonly available, so they may be used to measure different types of negative ion test kits. Using a high-precision negative oxygen ion measurement unit, long-term stability is good, and the drift is small. The World Health Organization has also made relevant regulations on the standard concentration of negative ions for clean air. Over 10 methods are built-in, including F-, Cl-, Br-, I-, NO3-, BF4-, NH4+, K+, Na+, Ca2+, Cu2+, Pb2+, Ag+ and etc. Plywood should be used as a measurement of the acid ion produced by the metal, as its name implies, and as an alternative of carbon dioxide gas in the form of an acid tester, and put the back into.

High performance air ion counter tester which is designed to measure negative ions generated by Radium, Monazite, Silica and other natural ores. Instrumental methods of analysis are faster, and more accurate and sensitive than simple chemical tests. For a variety of negative ion generator, air purifier, air conditioning, high concentration of the ion source to measure.It is a useful test kit to find the right negative ion generator and the potential value of this material. A negative oxygen ion detector can monitor air negative oxygen ions for forestry, environmental protection, meteorology, tourism, etc.
