Long-Distance Stable Transmission:
Based on LoRaWAN LPWAN technology, the transmission distance can reach 3-10 km (in open environments) with strong penetration through walls, workshops and other obstacles, suitable for large-scale deployment in chemical parks, warehouses and other wide-area scenarios.
Ultra-Low Power Consumption & Long Battery Life:
Adopting low-power design with built-in high-energy lithium battery, it can last 2-5 years in real-time monitoring mode, eliminating the need for frequent battery replacement and reducing operation and maintenance costs.
Multi-Dimensional Alarm Mechanism:
Supports sound-light alarm (on-site), APP push, SMS notification, platform pop-up and other alarm methods, with customizable alarm thresholds. Once Cl2 concentration exceeds the standard, it immediately triggers full-range reminders to ensure personnel safety.
Industrial-Grade Protection for Harsh Environments:
Housing with IP68 waterproof and dustproof design, resistant to high and low temperatures (-40℃~+85℃), corrosion and electromagnetic interference, suitable for stable operation in harsh environments such as chemical workshops, sewage treatment plants and underground pipelines.
Data Encryption & High Reliability:
ensure the security of data transmission and storage, preventing information leakage; the device has self-diagnosis function to real-time monitor sensor, battery and communication status, ensuring stable data output
Precise measurement
Stable performance
Low energy consumption

1.Q: Where is this sensor suitable for installation, and which areas should be avoided?
A: It is preferred to install the sensor 1-3 meters downwind from potential chlorine leakage points such as chlorine storage equipment and pipeline joints.
The installation height should be level with or slightly lower than the leakage source (to align with chlorine’s higher density than air, ensuring rapid detection of accumulated gas).
2.Q: How long does the sensor’s battery last? What should I do if the battery drains quickly?
A: Equipped with a low-power design, the sensor’s battery life can reach several years under regular data reporting frequency. However, the actual lifespan is affected by factors such as transmission distance and reporting interval.
Rapid battery drain may be caused by poor signal connection, which leads the device to repeatedly attempt network access. You can first check the signal strength between the sensor and the LoRaWAN gateway.
If the signal is normal but the battery still drains quickly, please consult us to verify if it is a device malfunction and apply for professional testing.
3.Q: What are the common reasons for intermittent data transmission of the sensor?
A: In addition to the excessive distance between the sensor and the LoRaWAN gateway, intermittent transmission may also be caused by the gateway being installed near metal surfaces (resulting in signal shielding) or other wireless devices in the vicinity occupying the communication frequency band.
You can try adjusting the gateway’s installation position first. If the problem persists, please consult us for a customized network channel planning and optimization solution.
The High precision Cl2 sensor also widely used for gas monitoring of Chemical production, Ward monitoring, Vegetable greenhouse, Livestock and poultry farms, Tunnel monitoring, Cold chain logistics vehicle, Cold storage monitoring, Biosafety laboratory.
