The installation needs to be stable, and the height between the center of the detector and the ground should be 1. Multi-measurement modes are supported, including Direct Reading mode, Standard Addition mode, Sample Addition mode and GRAN mode. Universal 9V battery power supply and automatic shutdown functions are adopted to facilitate users' use and save energy. If the item comes direct from a manufacturer, it may be delivered in non-retail packaging, such as a plain or unprinted box or plastic bag.

Before the lightning-prone season of each year, the lightning protection grounding, the collector shell, and the outer box grounding should be inspected and maintained. The air ion counter tester measures negative ions generated by natural ores such as Radium, Monazite and Silica. This negative ion tester is used to check whether the negative ion generator of positive and negative ions, or an negative charger is connected to your computer's usb port. Most purchases from business sellers are protected by the Consumer Contract Regulations 2013 which give you the right to cancel the purchase within 14 days after the day you receive the item.The key point in this scenario is the relay process, in which new ionization centers, when the corona discharge is ignited, arise against the background of spots of negative ion charge remaining from the spreading old centers. New: A brand-new, unused, unopened and undamaged item in original retail packaging (where packaging . It measures this number separately for positive and negative ions (+ and – ions are usually present simultaneously). The display shows the ion count within 2 seconds and it continues to display the ion density in the air, showing any changes within 2 seconds after they occur.

And the instrument can be used to determine whether the negative ion polarity produced by air negative ion generator or air purifier is correct, and the concentration of ion concentration is estimated. RP 4: Carry out simple test-tube reactions to identify: cations (Group 2, NH₄⁺), anions (Group 7 [halide ions], OH⁻, CO₃²⁻, SO₄²⁻). com is a great way to protect the user from any negative ion statement and any potential incidents with a negative ion tester. 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.

APPLICATIONS】This Negative ion testing is designed for test high level concentration of negative or positive air ion. This is a stereo phone plug identical to the plug on small headphones in which the ground has been cut. Observation is key in this practical, as all the information needed will be seen in the reactions present. 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).
