They started production of ion counters in 2002. Over 11,000 units of the inti-PRO's have been sold.Wallner P, et al. (2015). Exposure to air ions in indoor environments: Experimental study with healthy adults. DOI: Flame tests can be used to identify some metal ions (cations). Lithium, sodium, potassium, calcium and copper compounds produce distinctive colours in flame tests: t) the identification of Li⁺, Na⁺, K⁺, Ca²⁺ and Ba²⁺ ions by flame tests and Cl⁻, Br⁻ and I⁻ ions by their reactions with silver nitrate solution (including ionic equations)

We actually measured the voltage applied to the detector and the flow rate of the fan to calculate the ion count, Measurement range: The digit grouping symbol automatically appears depending on the ion count. For more details, please see the instruction manual. You have to be careful about what acid you add to do this. For example, you can't use dilute sulfuric acid, because that contains sulfate ions, and so will automatically give a white precipitate of barium sulfate.

If you are using barium chloride solution, you use hydrochloric acid. If you are using barium nitrate solution, you use nitric acid. Full teacher notes are available in the supporting resources booklet, including ideas for how to use this videoand the supporting resources as part of your teaching. Notes on running the practical experiment

You first acidify the solution you are testing with dilute hydrochloric acid and then add barium chloride solution.This product was developed by ANDES ELECTRIC CO., LTD. The company has been recognized as the leading manufacturer of ion counters. This is a test done in solution. If you have a solid, you must first dissolve it in pure water before you do anything else. The acid reacts with the carbonate ions to form carbon dioxide and water, and so gets rid of them before you add the barium chloride.

This is a cheap industrial-grade negative ion tester meter. It uses an external power supply to directly measure and display the number of negative ions. Small size and easy to move. It can be used with an outdoor weather station. Can measure indoor or outdoor negative ions. This is because the ion counter may provide inaccurate measurement as it is electronically charged due to the electrostatic induction caused by the large amount of ions.A 2013 review of scientific literature on negative ionization published between 1957 and 2012 found that ionization had no impact on people’s general mental health but did find a notable effect on people with depression. record detailed observations or numerical data (where appropriate) during chemical reactions, including discrete or continuous variables;
