Purchasing Guide

Based on real user feedback, we provide the following suggestions:

  • For procurement requirements that require the use of carbon monoxide sensors, it is recommended to prioritize confirming the range (such as 0-1000ppm or higher) and response time (usually less than 30 seconds). In industrial scenarios, additional attention should be paid to anti-interference capabilities and long-term stability.
  • When deploying in enclosed environments such as chemical plants or underground parking lots, it is necessary to choose carbon monoxide sensors with explosion-proof certification, while considering the compatibility of installation methods (wall mounted or pipeline mounted) and communication protocols (such as 4-20mA or RS485).
  • When selecting suppliers, priority should be given to product compatibility, business qualifications, enterprise activity, industry performance, and companies with industry data support. For example, suppliers who have been focusing on gas detection for more than 5 years can usually provide more stable technical solutions.
  • For home security or smart home scenarios, low-power wireless transmission carbon monoxide sensors are more suitable. When purchasing, it is necessary to verify their battery life (usually more than 3 years) and the reliability of the linkage alarm function.

Knowledge Base

Q

Carbon monoxide is a colorless and odorless highly toxic gas that can leak in both industrial production and daily life. Electrochemical carbon monoxide sensors have become the mainstream technology for professional level carbon monoxide detection due to their low power consumption, good linearity, high selectivity, and excellent repeatability. This article starts from the perspective of selection, helping technical personnel and safety management personnel make scientific and reasonable decisions.

Q

Carbon monoxide sensors have applications in multiple fields, such as: 1. Mine environmental monitoring 2. Fire monitoring 3. Intelligent gas water heater 4. Environmental monitoring of underground parking garage 5. Hospital smoking cessation treatment The above are only a part of the application scenarios. If you need to learn more information, please feel free to contact us at any time!

Q

GTH1000 Carbon Monoxide Sensor Product Introduction The sensor consists of a power supply, carbon monoxide detection probe, weak current detection amplification circuit, digital signal processor, display, signal output, etc. When the carbon monoxide sensor probe detects carbon monoxide, the probe outputs a corresponding current signal, which is amplified and processed before entering the microcontroller
