Product Overview
The RS485 pH, ORP and Temperature Sensor is a high-precision sensor for water treatment, smart agriculture, and environmental monitoring. It continuously measures pH, oxidation-reduction potential (ORP), and water temperature. Temperature compensation and configurable signal filtering help ensure stable readings under changing conditions. For easy integration, it supports RS485 Modbus RTU communication and 4.5–28 V DC operation. Moreover, its IP68-rated design, 3/4-inch NPT threads, and built-in electrical protection ensure reliable long-term use.
The RS485 pH, ORP and Temperature Sensor is a high-precision water quality sensor widely used in water treatment, irrigation, smart agriculture, pipelines, tanks, and environmental monitoring. It simultaneously measures pH, oxidation-reduction potential (ORP), and water temperature. Temperature compensation and configurable signal filtering help maintain stable readings under changing conditions. For easy integration, it supports RS485 Modbus RTU communication and low-power 4.5–28 V DC operation. Moreover, its IP68 design, 3/4-inch NPT threads, and built-in surge, reverse-polarity, TVS, and ESD protection ensure reliable long-term use. 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. Integrated pH and ORP Monitoring : Measures pH, oxidation-reduction potential (ORP), and temperature in a single device. These parameters provide a more complete understanding of water acidity, chemical balance, and oxidation-reduction conditions for water-quality assessment and process monitoring. Temperature Compensation and Flexible Calibration : Supports temperature-compensated pH and ORP measurements to reduce the influence of changing water temperature. Multi-point pH calibration and ORP standard-solution calibration help ensure measurement accuracy. Meanwhile, temperature offset adjustment and configurable signal filtering maintain stable readings across different environments.
Policies & Guidelines
Warranty, shipping, and purchasing information
Purchasing Guidelines▼
- Full payment is required before an order can proceed to fulfillment and shipment.
- All prices are listed in US dollars (USD) unless otherwise stated.
- Available payment methods are confirmed at checkout and may include bank transfer, supported credit or debit cards, and approved cryptocurrency payments.
- Cryptocurrency and foreign-exchange rates are fixed at the rate applied by the payment provider when payment is successfully processed and confirmed.
- 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.
Shipping Policy▼
- Shipping charges are calculated at checkout according to the delivery destination and are shown separately from the product price.
