The features and classification of formaldehyde detectors
The formaldehyde detector can detect six pollution indices in indoor air, including formaldehyde, benzene, ammonia, toluene, xylene, and TVOC, and can simultaneously detect six items. It can be widely used in environmental protection, construction, decoration, supervision and other companies to carry out indoor air quality testing business, and can also be used for daily research and teaching activities in scientific research institutions. Today, the editor will mainly introduce the characteristics and classification of formaldehyde detectors, hoping to help everyone.
Characteristics of formaldehyde detector:
Not affected by extreme high temperature and humidity environments, with humidity compensation function. Formaldehyde readings are displayed in ppm or mg/m3 units. Single key operation, capable of quick sampling and fast recovery time. The standard configuration includes a formaldehyde calibration source (valid for six months), which can complete the calibration process in just a few seconds. Randomly equip 10 phenol filters to eliminate the influence of phenol on readings. Select computer remote control software and adapter accessories to make the formaldehyde detector a wireless monitoring system. Users can also choose basic data processing devices to print data in real-time.
Classification of formaldehyde detectors:
1. Using probes for testing, representative instruments include XP-3084160, PPM400, etc., which are characterized by direct data reading and easy portability. The disadvantage is that they are greatly affected by temperature and humidity and require calibration with standard gases. The daily maintenance cost is low, and the probe is usually replaced every year, with a price of several thousand yuan.
2. Using spectrophotometry for analysis and reading, there are two types: the Japanese RIKEN FP-30 and the domestic Jida Little Swan. The former uses finished pills and has a compact instrument that can directly read after 15 to 30 minutes of sampling, with an accuracy of 0.005PPM. The maintenance cost is about 17 yuan per pill, and the machine does not require maintenance at all. The relative operation of the Little Swan is relatively complex, with tedious steps required after 15 minutes of sampling, and an accuracy of up to 0.01. The characteristics of this type of instrument are also prominent, with high accuracy, minimal interference from gases, and compensation for temperature and humidity.
3. Handheld formaldehyde detector is a handheld instrument that can continuously measure formaldehyde. This product is suitable for environmental monitoring, industrial production, chemical and other places with formaldehyde.
4. The portable formaldehyde detector can be zeroed at the testing site without the need for outdoor air. Applied for indoor formaldehyde gas detection in public places, indoor formaldehyde gas detection in civil buildings, and formaldehyde content detection in building materials.
