About this deal

com is a great way to protect the user from any negative ion statement and any potential incidents with a negative ion tester. When the negative ion meter has worked for a long time, we need to perform zero adjustments for calibration. Instrumental methods of analysis are faster, and more accurate and sensitive than simple chemical tests. The meter uses a standard 9 volt battery, but an AC adapter and a rechargeable battery system are two options. They can improve respiratory diseases and cardiovascular and cerebrovascular diseases, lower blood pressure, increase appetite, and regulate the body’s physiological functions.

This instrument is a true ion density meter, based on a Gerdien Tube (Gerdien Condenser) design, and it contains a fan which pulls air through the meter at a calibrated rate. For a variety of negative ion generator, air purifier, air conditioning, high concentration of the ion source to measure. At least three months, a special inspection and cleaning, and maintenance of the collector, circuit, and gas circuit should be carried out. 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. This is a stereo phone plug identical to the plug on small headphones in which the ground has been cut.

New: A brand-new, unused, unopened and undamaged item in original retail packaging (where packaging . PORTABLE DESIGN】This Air Ion Tester Meter has simple and small design, easy to carry, very easy to hang as a necklace. Test and evaluate various solid negative ion products, such as negative ion bracelet, negative ion cushion, energy cup, sweat room, rock plate bath, paint and coating, etc.

This experiment has been reproduced from Inspirational Chemistry, Royal Society of Chemistry, London, p. The World Health Organization has also made relevant regulations on the standard concentration of negative ions for clean air.A white precipitate close precipitate A suspension of particles in a liquid formed when a dissolved substance reacts to form an insoluble substance, eg in a precipitation reaction. It measures this number separately for positive and negative ions (+ and – ions are usually present simultaneously). The acid tester pushes the metal into its harmful state, and if any metal is stuck with the metal ion, it should be put on the back of the acid with some acid in it.
