Portable ethylene detector,Fruit cold storage ethylene detection factory,Uses: Preservation of fruits and vegetables

Shenzhen Wanyi Technology Co., Ltd. has used the technology of American Environmental Sensor Technology Company to develop the CESTSEN brand gas detector for nearly 20 years. The company specializes in the research and development, production, sales and after-sales service of gas detection equipment. The sensor core component sensor is provided by sensor manufacturers from the United States, Britain, Germany, etc., and can be used after careful selection by the Wanyi technology engineer team. With strict calibration method in the laboratory, Wanyi Technology strives to create gas detection equipment with high accuracy, safety, easy operation and reliable quality for the

industry customers.

EST-101-C2H4-10ppm Ethylene detector is a portable gas concentration measuring instrument. It adopts high-precision circuit design. The core adopts imported sensor chip. After Wanji Technology develops calibration, signal amplification, calibration calibration and strict testing, it is delivered to the factory. .
The instrument is designed and produced in accordance with relevant national standards:
GB/T18883-2002 "Indoor Air Quality Standards" GB3095-1996 "Environmental Air Quality Standards"
GB50325-2010 "Code for Indoor Environmental Pollution Control of Civil Building Engineering"
GB50325-2001 Code for indoor environmental pollution control of civil construction projects
GB12358-2006 "General technical requirements for workplace gas detection and alarm devices" industrial standard
EU 2002/231/CE Directive Taiwan's "Indoor Air Quality" Standard
EMC electromagnetic compatibility related test standard, European standard EN55022, American standard FCC

Mainly used:

Fruit and vegetable preservation, storage, fruit ripening, cold storage, agricultural research Institutes of oranges, bananas, mangoes, apples, nectarines and other fruits produced by the determination of ethylene concentration, fruit storage warehouse, adding ripening agent test research.
Petrochemical Ethylene is one of the largest chemical products in the world. The ethylene industry is the core of the petrochemical industry. Ethylene products account for more than 75% of petrochemical products and occupy an important position in the national economy. Ethylene production has been used as one of the important indicators to measure the development level of a country's petrochemical industry.
