[Gastron GTD-5000](https://www.cwlyautomation.com/product/22.html "Gastron GTD-5000") series Gastron ranks first in the domestic gas detector market in South Korea. GTD-5000 series: This is a pump-type gas detector with the following advantages that make it in high demand. The GTD-5000 series has the following advantages: **Detection performance advantages** A wide range of detection types: It can detect a variety of gases such as combustible gas, oxygen, toxic gas, VOC gas, etc. For example, [GTD-5000F](https://www.cwlyautomation.com/product/1741.html "GTD-5000F") can detect VOC gas, and GTD-5000 can detect combustible gas and oxygen, etc. High accuracy: It can accurately detect gas concentration with an accuracy of ±3%/full scale, such as GTD-5000VOC can accurately detect VOC gas in the range of 5ppb-300ppm. Quick response: Built-in high-efficiency pump, it can quickly inhale and detect leaking gas, such as the response time of GTD-5000VOC < 5 seconds/90% ratio. **Functional design advantages** Built-in sampling pump: equipped with a diaphragm pump as a sampling method, such as GTD-5000VOC, which can stably extract gas samples in the environment for detection. Easy to replace sensors: using barrel-type sensor accessories, easy to replace, reducing maintenance costs and time costs. Multiple output signals: supports 4-20mA DC output signal, and can also be equipped with RS-485 Modbus isolated serial data communication or PoE function, which is convenient for integration with the monitoring system. Complete alarm function: with 2-level alarm and 1-level fault display, and output alarm signals through relay contacts, can issue alarms in time. **Operation and display advantages** Equipped with display screen: there are 4-digit gas concentration display and fine LCD display, which can clearly display information such as gas concentration and alarm status. Easy operation: the front switch can be used for calibration, maintenance, alarm setting and other operations, and the operation is simple and easy to understand. Intuitive working mode display: 4-LED indicator light can display working modes such as power supply, 2-level alarm, 1-level fault, etc., which is convenient for quick judgment of equipment status. **Environmental adaptability advantage** Wide temperature range: The working temperature is generally - 20℃～+60℃, which can adapt to a variety of harsh working environments such as cold and high temperature. Good humidity adaptability: The operating humidity is 5%～99% RH (non-condensing), and it can also operate stably in a humid environment. Easy installation: It adopts wall-mounted installation and can be flexibly arranged in the area where detection is required.
