1 PCS Mini Car Air Ion Tester Meter Counter Air Ion Tester Meter Counter for Negative Air Ion Generator with a Necklace

Product Information

The measurement range is 0-5 million, 0-50 million, 0-100 million, 0-200 million, and 0-500 million for choose. Wider range => It covers negative ion counts of up to 99,999(pcs/cc), while the EB-17 covers only up to 199,900(pcs/cc). To evaluate a sample's ion-specific performance, the best resource is slope S, also known from pH measurement.

Individual atoms consist of protons, which have a +1 charge; neutrons, which have no charge; and electrons, which have a -1 charge. Moving average mode => It measures the average of 16 negative ion counts collected during 35 seconds.

A soil sample may be dried, crushed, and/or sieved, then extracted into a water or salt solution prior to ISE testing. A rotary offset control fine-tunes the internal amplifier so the display reads zero if no ions are present (or whenever the meter is on STANDBY). To avoid these misconceptions introduce and emphasise the correct use of the terms ‘ion’ and ‘molecule’ from the outset. You may need to dissolve a sample of salt in a little distilled water if you are given solids, rather than solutions.

Describe and explain the simple test-tube reactions of: M²⁺(aq) ions (limited to M = Fe and Cu), and of M³⁺(aq) ions (limited to M = Al and Fe), with the bases OH⁻, NH₃ and CO₃²⁻. Diagnostic multiple-choice questions are a great way to explore learners’ misconceptions by investigating reasoning behind their answers. Note: The detector on the back side of the body has to maintain contact with ores while the measurement is in progress.

The negative ion tester has a liquid crystal display, so the value can be seen even in a dim environment. The housing of this negative ion meter is made of high-strength stainless steel, which is sturdy and durable. Introducing the electron now, before learners meet the other sub-atomic particles, can help to embed the idea that the loss of electrons results in a positively charged ion, and may help reduce confusion later on. When air passes through the cylinder, the ions hit the cylinder body and the shaft to generate discharge, and the discharge signal is recorded, so that it can be positive in the air. A simple way of remembering what acid is safe to use is to choose the one related to the barium compound you are using.
