The TD1094-NOX pumping nitrogen oxide detector is a high-performance gas detection device designed for monitoring nitrogen oxides (NOx) in both ambient and confined environments. It features an advanced electrochemical sensor imported from abroad, ensuring precise and reliable measurements. The device is equipped with a USB interface that enables fast data transfer, allowing users to download and print collected data easily. Its LCD dot matrix display provides clear visibility of key information such as gas type, units, concentration levels, maximum readings, local time, and ambient temperature. The user interface supports both Chinese and English, making it accessible for a global audience.
Users can switch between different gas concentration units—PPM and mg/m³—quickly and conveniently. The built-in micro-sampling pump offers ten adjustable suction settings, providing flexibility in various testing scenarios. The detector is rated at ExiaIICT4 for explosion-proof performance, making it suitable for use in hazardous areas.
This device includes self-checking and zero calibration functions to ensure accuracy and reliability. It also incorporates temperature and pressure compensation technology, which helps maintain precision under varying environmental conditions. Two-level sound and light alarms can be set to alert users when dangerous gas levels are detected. The device uses a large-capacity lithium polymer battery, offering long operational time and adjustable pump suction strength. Its durable casing is made from high-strength engineering plastic, providing resistance to water, dust, and impact, while also featuring non-slip design elements for ease of handling.
The TD1094-NOX detector is ideal for a wide range of applications, including furniture manufacturing, flooring, wallpaper installation, paint and coatings, gardening, interior decoration, textile dyeing, paper production, pharmaceuticals, medical facilities, food processing, antiseptic treatments, fertilizer production, resin and adhesive manufacturing, pesticide formulation, raw material testing, process monitoring, breeding plants, waste treatment, perfume production, biopharmaceuticals, home environmental monitoring, animal husbandry, greenhouse farming, logistics, brewing, and agricultural activities.
In terms of specifications, the TD1094-NOX detects nitrogen oxides using an electrochemical principle. It employs a pumping sampling method with a flow rate up to 1L/min and offers ten adjustable suction positions. The measurement range includes 0–10ppm, 0–20ppm, 0–50ppm, 0–100ppm, 0–500ppm, 0–1000ppm, 0–2000ppm, and 0–5000ppm, with custom ranges available upon request. The resolution varies depending on the range, from 0.001ppm to 1ppm. The device has an accuracy of ±2% of full scale, with a response and recovery time of ≤10 seconds. Repeatability and linearity errors are within ±1%, and the zero shift is less than ±1% per year.
The display supports multiple languages and gas unit conversions, while the operating temperature range is -40°C to 70°C, with humidity resistance up to 95% RH. It features a two-level alarm system (sound, light, and vibration), and operates for up to 100 hours without the pump. The dimensions are 205 × 75 × 32 mm, and the weight is 300g, making it compact and portable for field use.
