Product Introduction

The SHC37S model self-contained CTD sensor is a sensor specifically designed for measuring temperature, depth, and conductivity in coastal and open ocean waters, featuring high accuracy, low power consumption, and strong stability and reliability. The titanium alloy housing offers excellent corrosion resistance and can withstand pressures up to 7000 meters of water depth; conductivity measurement employs a high-precision three-electrode sensor with a conductivity accuracy of ±0.003 mS/cm; with an ultra-low power consumption design, the sensor can operate continuously for over one year, and the large-capacity memory card meets user data storage requirements; under low power consumption conditions, the communication rate can reach 115200 bps; both the electrical interface and communication method can be customized according to user requirements.


The SHC37S model self-contained CTD sensor is fully independently developed by our company, with complete intellectual property rights, and has obtained multiple patents, with 100% domestic production of core components. The company possesses a full set of experimental environments and equipment for temperature, pressure, and salinity, capable of supporting the entire lifecycle of the instrument from design, production, and calibration to testing and maintenance, providing sufficient assurance for the quality and reliability of the sensor.
