Brief Introduction
In order to regulate the development of the industry and ensure consumer interests, the "Portable Formaldehyde Detector" (T/CAQI 140-2020) group standard initiated by the China Air Purification Industry Alliance and approved by the China Quality Inspection Association was implemented on February 6, 2021. Based on years of research and development of electrochemical formaldehyde gas sensing technology and early industrialization of client supporting experience, Sifang Optoelectronics Co., Ltd. was invited to participate in the "PortableFormaldehyde detector》Preparation of standards. The standard is applicable to portable formaldehyde detectors used for indoor air quality testing and is not suitable for use in corrosive and explosive gas special environments. Among them, the detection performance of portable formaldehyde detectors that consumers are more concerned about is divided into three levels: A, B, and C according to detection accuracy.
Under normal environmental conditions, when the formaldehyde concentration is not higher than 0.3 mg/m ³, repeat the measurement 6 times at the same concentration. The repeatability error of the indication is expressed as relative standard deviation and should not exceed ± 10%.
This standard not only specifies the detection error and measurement accuracy of portable formaldehyde detectors, but also provides clear requirements for performance indicators such as grade determination standards, repeatability, and drift. The new standard will guide technological innovation in the portable formaldehyde detector industry, providing consumers with more and better choices.
Formaldehyde gas sensor technology
As the core component of the detector, the performance and reliability of the sensor directly determine the accuracy and precision of the detection results.
Sifang Optoelectronics is a high-tech enterprise specializing in the research and development, production, and sales of gas sensors and gas analysis instruments. The company was listed on the Science and Technology Innovation Board on February 9, 2021 (code: 688665). The company insists on technological innovation in the field of electrochemical formaldehyde detection. Through the integration of highly sensitive formaldehyde sensor membranes with MEMS VOC sensors, temperature and humidity sensors, as well as specialized formaldehyde gas decomposition membrane technology, the dual sensor differential method is used to eliminate the influence of alcoholsElectrochemical formaldehyde gas sensorInterference in concentration measurement and elimination of the influence of temperature and humidity on the accuracy of measurement data. At the same time, based on the operating status data of the air purifier and fresh air system, combined with the operating scenarios that need to be considered, multi-sensor information fusion is carried out to output accurate formaldehyde concentration values. After continuous product upgrades, Sifang Optoelectronics has launched the fourth generation anti-interference electrochemical formaldehyde sensor CB-HCHO-V4, which has been launched in bulk.
Product Features
1. Creatively utilizing dual formaldehyde sensor membrane detection technology, resistant to cross gas interference such as alcohol, with alcohol interference<1%, capable of simultaneously outputting HCHO, TVOC, VOC, temperature, and humidity parameters.
2. Accurate measurement with high precision. The Sifang photoelectrochemical formaldehyde sensor uses Finland's expensive laser photoacoustic spectroscopy formaldehyde analyzer as the standard instrument, achieving a resolution of 0.1PPb.
3. High stability, the formaldehyde sensor maintains stable data during continuous long-term operation.
4. Full range temperature and humidity correction, unaffected by temperature and humidity. Using an independent temperature and humidity sensor chip, real-time temperature and humidity compensation is performed to eliminate the influence of temperature and humidity changes on the measured values.
5. The service life can reach 6 years. Adopting a porous ceramic reaction chamber and a slow electrolyte release structure, the sensor's lifespan is extended.
Four sided photoelectric formaldehyde gas detector Mini FM01
The Sifang Optoelectronic Mini Formaldehyde Detector FM01 is a USB plug-in air quality detector with built-in high-precision dual formaldehyde sensors. It uses nano formaldehyde decomposition material film, automatic multi-point calibration, temperature compensation algorithm, and can accurately measure the concentration of formaldehyde in the air in real time, without interference from cross gases such as VOCs. The detector can display the concentration and level of formaldehyde in real time, and beep to remind in high concentration environments.
1. Four party photoelectric mini formaldehyde detector FM01 is compact in size and is the formaldehyde in consumers' pocketsvanguard.
2. USB interface design, plug and play; If formaldehyde exceeds the standard, there will be a sound reminder, which is flexible and convenient.
3. Core formaldehyde sensors independently developed, each sensorThe SN code is traceable, resistant to alcohol interference, and has a sensitivity of up to 0.001mg/m ³.
4. Suitable for office environment testing, new house formaldehyde testing, and in car environment testing, it is more suitable for travel and can easily monitor the formaldehyde concentration in the environment anytime and anywhere.
