Product Overview
The RS485 Oxygen Concentration O2 Sensor is a high-precision, multi-parameter sensor designed for continuous oxygen monitoring. It is widely used in HVAC, laboratories, scientific research, indoor air monitoring, and environmental monitoring. The sensor measures oxygen concentration, oxygen partial pressure, temperature, and barometric pressure, with readings updated every second. Its non-electrochemical luminescence-quenching technology and long-life SST® O2 sensing element provide accurate and stable measurement across a 0–25% range. For easy integration, it supports RS485 Modbus RTU communication and low-power 9–28 V DC operation, while its IP50 wall-mounted design allows for convenient installation. Built-in surge, reverse-polarity, TVS, and ESD protection further enhance reliability during long-term operation.
The RS485 Oxygen Concentration Sensor uses luminescence-quenching optical technology to measure ambient oxygen partial pressure, oxygen concentration, temperature, and barometric pressure. For easy system integration, it supports RS485 Modbus RTU communication. Its compact IP50 wall-mounted enclosure incorporates an SST® O₂ sensing element with a service life of more than two years, ensuring high accuracy and excellent stability. Meanwhile, the low-power 9–28 V DC operation, together with reverse-polarity, surge, TVS, and ESD protection, enhances reliability during long-term use. With these features, the sensor is well suited for scientific research, HVAC and ventilation control, routine weather monitoring, and environmental monitoring. This sensor is available with an RS485 Modbus RTU interface. It is compatible with the SenseCAP S2100 LoRaWAN® Data Logger , enabling low-power, long-range data transmission over LoRaWAN® networks. Note: This sensor is rated IP50 and is designed for indoor environments. It is not suitable for direct outdoor exposure or locations with water ingress risks. Comprehensive Oxygen Monitoring: Measures ambient oxygen partial pressure, oxygen concentration, temperature, and barometric pressure in one device. This provides the essential parameters required for evaluating oxygen conditions and understanding how environmental changes affect oxygen concentration. Configurable Measurement and Data Output: Provides both original and calibrated values for oxygen partial pressure, oxygen concentration, temperature, and barometric pressure.
Policies & Guidelines

- Shipping charges are calculated separately at checkout based on the delivery destination and are not included in the displayed retail price.
- After payment is confirmed, an electronic invoice is issued and made available in the Customer account.
- Hardware orders may be cancelled for a full refund before allocation, custom preparation, packing, or dispatch begins.
- If a bank payment is confirmed after the selected production batch has closed, the Customer may choose the next available batch or request a full refund.
- Approved refunds are initiated within seven business days and are returned through the original payment method, subject to the applicable verification requirements.
Warranty Policy▼
- Eligible hardware purchased directly from {brandname} is covered by a 365-day warranty starting from the date of delivery.
- Warranty coverage is verified through the product serial number and the original sales record.
- Covered faults include verified manufacturing defects, internal component failures not caused by the Customer, delivery damage, and hardware received in a non-operational condition.
- Depending on the technical findings, the resolution may include remote diagnosis, replacement parts, repair, or an equivalent replacement.
- For approved warranty repairs, {brandname} covers standard return shipping after the repair or replacement is completed.
- The Customer is responsible for shipping an authorized warranty return to the service location specified in the RMA case.
- Unauthorized firmware, third-party overclocking, or unsupported modifications may affect warranty coverage only where they caused the fault or prevent reliable diagnosis.
- Damage caused by improper electrical installation, power surges, liquid exposure, inadequate cooling, operation outside specified environmental limits, or tampering with the serial number may be excluded from warranty coverage.
- Covered repairs are targeted for completion within 10 business days after receipt at the authorized service location. If additional time is required, the Customer will receive a written update or an alternative resolution plan.
