Air ion tester installation
- It can be installed and fixed with screws. The dimensions of the mounting holes are as follows (unit: mm): Note that the device must be placed vertically, otherwise, it will affect the accuracy of the data.
- The installation needs to be stable, and the height between the center of the detector and the ground should be 1.5m.
- The shell and outer box of the collector should be well-grounded.
1. The collector, air inlet and outlet, fan, etc. should be cleaned once a month.
2. At least three months, a special inspection and cleaning, and maintenance of the collector, circuit, and gas circuit should be carried out.
3. 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.
FAQs - Negative Ion Detector
Negative oxygen ions are the free electrons generated by the ionization of molecules in the air under the action of high pressure or strong rays, and most of the free electrons are obtained by oxygen. One type of negatively charged oxygen ions (the electrons are negatively charged) that gain some electrons are called “negative oxygen ions“, and the other is the health killer superoxide radical.
The negative oxygen ions in the air have a good effect on the environment and the maintenance of human health. In medicine, negative oxygen ions are known as “vitamins in the air” and “longevity factor”. They can effectively decompose and reduce harmful gases in the air, making people feel refreshed and refreshed, enhancing skin elasticity, relieving aging, preventing health. They can improve respiratory diseases and cardiovascular and cerebrovascular diseases, lower blood pressure, increase appetite, and regulate the body’s physiological functions.

Air negative ion concentration refers to the number of negative ions per unit volume of air, and its unit is ions/cm³.
The overall structure of the negative ion detector is composed of 3 concentric cylinders. The outer cylinder body and the inner shaft are electrodes. 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. , The number and size of negative ions are measured.
- After powering on the negative oxygen ion detector, select the working mode. There are three options: low range, high range, and automatic range switching.
- For example, for a device with a 0~5 million range, the low range mode can measure negative oxygen ion concentrations within 0~300,000 ions/cm³. The high range mode can measure concentrations within 0~5 million ions/cm³. However, within the 0~300,000 range, the accuracy is lower, and there is no intermediate range.
- In automatic range switching mode, the measurement range is 0~5 million with high accuracy, but when the value exceeds 300,000 ions/cm³, there will be a one-minute delay for range switching.
- Note: When selecting different range modes for measurement, zero calibration is required.
- Can be fixed using screws; the mounting hole diameter is 4.5mm. It is important to ensure the negative oxygen ion detector is placed vertically, with the air inlet and outlet unobstructed to avoid affecting data accuracy.
- Installation must be stable, with the detector center positioned at a height of 1.5 meters from the ground.
- The collector’s housing and outer enclosure should have proper grounding.
- Equipped with lightning protection facilities; grounding resistance should be less than 4Ω.
- Optional protective fencing can be installed; fence height should not exceed 1.2 meters, and the distance between the instrument and the fence should be greater than 2.0 meters.
