    Overview

    This SUCH oxygen gas transmitter with display is a fixed O2 sensor for real-time oxygen concentration monitoring. It measures 0-30%Vol or 0-25%Vol oxygen levels with OLED display, fast response, and RS485, 4-20mA, 0-5V or 0-10V output. Suitable for factory warehouses, food storage, livestock farms, greenhouses, and industrial air quality monitoring.

    Feature

    Oxygen transmitter feature

    • High-density material housing with built-in waterproof seal for moisture and dust resistance, enabling the oxygen transmitter to withstand harsh on-site detection environments.
    • Standard Modbus-RTU communication protocol with optional RS485/4-20mA/0-5V interfaces. Configurable communication address and baud rate, with a maximum communication distance of 2000 meters.
    • The oxygen transmitter employs a high-sensitivity gas detection probe paired with an OLED display for direct on-site data viewing, ensuring stable signals and high accuracy.
    • Suitable for industrial and agricultural environments including factory warehouses, food storage facilities, farms, ranches, and horticultural gardens.

    FAQ
    ❯

    The digital oxygen transmitter should be installed in a location free from impact, vibration, and strong electromagnetic interference, and easily accessible for maintenance. The clearance between the installation site and surrounding process pipelines or equipment should not be less than 0.5m. It is recommended to install the transmitter 0.5m to 1.0m below the release source.

    ❯

    When testing the oxygen transmitter's response to target gases, it is recommended to use corresponding gas standard substances with concentrations not exceeding the device's measurement range. Abnormal readings resulting from non-recommended testing methods are not covered. Oxygen sensors must not be used long-term in environments with oxygen concentrations below 10% VOL. Abnormal readings caused by low-oxygen environments are not covered.

    ❯

    This RS485 signal output oxygen transmitter supports multiple sensors connected to a single 485 bus. Theoretically, one bus can accommodate up to 254 RS485 sensors. Connect the other end to a PLC with an RS485 interface, link to a microcontroller via an RS485 interface chip, or use a USB-to-RS485 adapter to connect to a computer. Configure and test using the sensor configuration tool provided by our company (only one device can be connected at a time when using this configuration software).

    Keeps Our Barn Safe
    We've been using this oxygen transmitter in our cattle barn, and it’s been a real help. The readings are accurate, and it’s easy to see oxygen levels at a glance. It gives us peace of mind, especially during winter when ventilation can be tricky. So far, it’s been reliable every day.
