The TD1140-C2H4 portable ethylene detector is designed to monitor the concentration of ethylene in both ambient and confined environments. It features an automatic self-check function, zero calibration, and a one-touch factory reset, ensuring accurate and reliable gas detection. The device also includes temperature and pressure compensation, allowing it to deliver two-stage sound and light alarms under varying environmental conditions. Users can set custom alarm thresholds, making it adaptable for different applications.
Equipped with a high-capacity lithium polymer rechargeable battery, the detector uses a pumping sampling method with adjustable suction power, enhancing its versatility. The durable housing is made from high-strength engineering plastic, offering non-slip, waterproof, dustproof, and explosion-proof protection. It comes in a premium aluminum alloy suitcase, making it easy to carry and protect during transport.
This ethylene detector utilizes an imported high-precision electrochemical sensor, ensuring reliable performance. It supports USB interface data transfer for high-speed communication, allowing users to download and print recorded data. The LCD dot matrix display shows key information such as gas type, unit, concentration value, maximum reading, local time, and ambient temperature. The user-friendly interface supports both Chinese and English languages, and users can quickly switch between gas concentration units like PPM and mg/m³.
The built-in micro-sampling pump offers ten levels of adjustable suction power, making it ideal for various detection scenarios. It is certified for explosion-proof use, with an ExiaIICT4 rating, ensuring safety in hazardous environments. The device operates within a wide temperature range (-40°C to 70°C) and humidity level (0-95% RH), making it suitable for both indoor and outdoor use.
The TD1140-C2H4 is widely used in industries such as furniture manufacturing, flooring, wallpaper, coatings, horticulture, interior decoration, pharmaceuticals, food processing, agriculture, and more. It is particularly useful in environments where ethylene levels need constant monitoring, such as warehouses, production workshops, greenhouses, and waste disposal facilities.
In terms of specifications, the detector can measure ethylene concentrations ranging from 0-100ppm to 0-1000ppm, with a resolution of 0.01ppm to 1ppm depending on the range. It offers a response time of less than 10 seconds and a recovery time of under 10 seconds. The device maintains high accuracy, with a repeatability of ±1% and linearity error of ≤±1%. Its zero drift is limited to ±1% per year, ensuring long-term stability.
With a compact size of 205 x 75 x 32mm and a weight of just 300g, the TD1140-C2H4 is lightweight and easy to handle. It provides multi-mode alarms—sound, light, and vibration—to ensure users are always alerted. The device can operate for up to 100 hours without using the pump, making it ideal for extended field operations.
