Negative oxygen ion formaldehyde pm2.5pm10 temperature and humidity four-in-one detector

Instrument Introduction

HED-FY4 type negative oxygen ion formaldehyde pm2.5pm10 temperature and humidity four-in-one detector is a high-precision, professional air negative ion, formaldehyde, pm2.5, pm10, air temperature and humidity detection and analysis instrument. It adopts an advanced cylindrical capacitor structure negative (oxygen) ion capture mechanism to capture the negative (oxygen) ions contained in the atmosphere, and then uses a unique algorithm to perform accurate statistical calculations. It has the advantages of stable measurement process, rapid response, and accurate measurement results. At the same time, it has strong anti-electromagnetic, static electricity, and electromagnetic wave interference capabilities, has good sensitivity and capture ability for small-particle negative ions, and has excellent overall performance.

HED-FY4 type multifunctional negative ion detector is easy to operate, and the 5.0-inch full-color large screen displays real-time measurement data, instrument working status, and automatically calculates the average value. Operators can quickly measure without professional training without any basic knowledge.

Application Scope

The four-in-one detector for negative oxygen ion, formaldehyde, PM2.5, PM10, temperature and humidity in the air measures the atmospheric negative oxygen ion concentration, formaldehyde concentration, PM2.5, PM10, temperature and humidity in real time. It is the preferred tool for measuring and demonstrating the concentration of negative ions in environmental testing, nano-coatings, negative ion health products, negative ion home improvement building materials, indoor testing, air treatment, air purifiers and their products.

Working Principle

The principle of "capacitive inhalation method" is used to detect negative ions and measure the concentration of negative ions in the air. A quantitative polarization voltage is loaded on the polarization plate (or bias plate) of the ion sensor (or collection bucket, collection tube), and then the measured air is allowed to pass through the sensor at a set speed. Specific small-particle negative ions in the air are deflected under the action of the electric field and captured by the collection plate. The negative charge of the collected negative ions is processed by the collector to calculate the charge concentration value of the negative ions.
