Key Issues Explained in One Go with Diffusion-Type Toxic and Harmful Gas Detectors!

In chemical, mining, and environmental monitoring scenarios, diffusion-type toxic and hazardous gas detectors are crucial equipment for ensuring personnel and environmental safety. However, many people have questions about their functions, performance, and applicable scenarios. Below, Zetron Technology will provide a detailed explanation of the core information of this equipment through a Q&A format.

Q: How many gases can the diffusion-type toxic and harmful gas detector detect simultaneously? Does it support customization?

A: This detector can detect up to 1-4 gases simultaneously, and the types of gases to be detected can be selected according to actual needs. The device also supports OEM or ODM customization and can be equipped with RS485 communication and environmental temperature and humidity measurement functions. Other special functions or communication interfaces can also be customized as needed to adapt to different usage scenarios.

Q: How are the detection accuracy and sensor quality of the equipment guaranteed? Is the display clear?

A: Zetron Technology's toxic and harmful gas detectors use sensors from imported brands such as Honeywell, Japan's Nemoto, and the UK's CITY. The detection principles cover various types, including electrochemical, infrared, and catalytic combustion, ensuring accurate detection data. For display, it features a 2.31-inch high-definition color screen that can display gas concentration, alarm status, time, and battery level in real time. The menu interface uses high-definition simulated icons to indicate functions and supports switching between Chinese and English interfaces; the default Chinese interface is easier to operate.

Q: What is the device's storage capacity? Can the data be exported for analysis?

A: The device comes standard with a data storage capacity of 100,000 records, supporting real-time storage, scheduled storage, and the option to store only alarm concentration data and its corresponding time. Data viewing and export are convenient; data can be viewed and deleted locally, or uploaded to a computer via USB. Combined with host computer software, data analysis, storage, and printing can be completed to meet subsequent data traceability needs.

Q: How are the device's protective performance and battery life? What are the alarm methods?

A: In terms of protection, the toxic and harmful gas detector is splash-proof, dustproof, explosion-proof, and shockproof. Its intrinsically safe circuit design is anti-static and anti-electromagnetic interference, achieving an IP65 protection level. It has passed national standard testing and CPA metrological instrument type certification, adapting to complex working conditions. Regarding battery life, it is equipped with a 3000mAh rechargeable polymer battery, enabling long-term continuous operation. The USB charging port also features multiple protections against overcharge and overvoltage, along with a 5-level accurate battery level display for easy monitoring of battery status. It offers a variety of alarm methods, including audible, visual, vibration, and alarm signals. It also supports undervoltage, fault, and shutdown alarms. Alarm values are configurable, and alarm modes can be selected as low alarm, high alarm, or range alarm, providing timely risk alerts.

Q: Does the device require frequent calibration during use? Can the display mode be adjusted?

A: Zetron Technology's electronic toxic and hazardous gas detector features automatic zero-point tracking, making it less susceptible to zero-point drift during long-term use. It also supports multi-level calibration and can automatically identify and prevent erroneous concentration calibration, reducing maintenance costs. The display mode is flexibly switchable, capable of simultaneously displaying four gas concentrations, or displaying single-channel concentrations or real-time curves in large font in a cyclical manner. The cycling mode (automatic/manual), whether to display maximum/minimum values, and gas names for each channel can all be set. Historical records can also be viewed to adapt to different usage habits.

That concludes our sharing on toxic and hazardous gas detectors. We hope this has given you a better understanding. See you next time!
