The TD1140-C2H4 portable ethylene gas detector is designed to monitor the concentration of ethylene in both open environments and confined spaces. It features an automatic self-check function, zero calibration, and a one-touch factory reset, ensuring accurate and reliable gas monitoring while minimizing the risk of misuse. The device also includes temperature and pressure compensation, allowing it to provide two levels of sound and light alarms under varying environmental conditions. Users can set custom alarm points, and the built-in micro-pumping sampling system allows for adjustable suction strength.
This detector uses an imported high-precision electrochemical sensor, ensuring high accuracy and stability. It comes with a USB interface for fast data transfer, enabling users to download and print recorded data. The LCD dot matrix display shows key information such as gas type, unit, concentration, maximum reading, local time, and ambient temperature. It supports both Chinese and English interfaces, making it user-friendly and easy to switch between units like PPM and mg/m³.
The TD1140-C2H4 is equipped with a built-in micro-sampling pump, offering ten adjustable suction levels. It is certified for explosion-proof use, with an ExiaIICT4 rating, and features a durable housing made from high-strength engineering plastic. The device is non-slip, waterproof, dustproof, and explosion-proof, making it ideal for harsh working conditions. It also comes in a premium aluminum alloy suitcase for convenient transport and storage.
This ethylene gas detector is widely used in various industries, including furniture, flooring, wallpaper, coatings, horticulture, interior decoration, dyes, paper, pharmaceuticals, medical, food, antiseptics, fertilizers, resins, adhesives, pesticides, raw materials, sample testing, and plant breeding. It is suitable for factories, production workshops, biological and pharmaceutical facilities, household environmental monitoring, animal husbandry, greenhouse cultivation, warehousing, logistics, brewing, and agricultural production.
In terms of specifications, the TD1140-C2H4 detects ethylene (C2H4) using an electrochemical principle. It operates on a pumping method with a flow rate up to 1L/min and offers ten adjustable suction levels. The detection range is available in multiple options: 0-100ppm, 0-200ppm, 0-500ppm, and 0-1000ppm. The resolution varies depending on the range, with 0.01ppm for 0-100ppm, 0.1ppm for 0-200ppm and 0-500ppm, and 1ppm for 0-1000ppm. The accuracy is within ±2% of full scale.
The device has a response time of ≤10 seconds and a recovery time of ≤10 seconds. It maintains a repeatability of ≤±1% and linearity error of ≤±1%. The zero drift is ≤±1% per year. The display uses liquid crystal dot matrix technology, and the operating language supports both Chinese and English. It can measure gas units in PPM or mg/m³ and switch between them quickly.
The operating temperature range is from -40°C to 70°C, and humidity resistance is up to 95% RH. It features a dual alarm mode—sound, light, and vibration—for enhanced safety. The battery life is up to 100 hours when the pump is off. The dimensions are 205×75×32mm, and the weight is approximately 300g. This makes the TD1140-C2H4 a compact, powerful, and reliable solution for ethylene gas detection in a wide range of applications.
