Product Introduction

The SHC37R Direct-Reading Conductivity-Temperature-Depth (CTD) Sensor is a sensor specifically designed for temperature, depth, and conductivity measurements in coastal and open ocean environments, 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, achieving a conductivity accuracy of ±0.003 mS/cm. The ultra-low-power design enables a communication rate of up to 115200 bps under low-power operating conditions. Both the electrical interface and communication protocol can be customized according to user requirements.

 

The SHC37R Direct-Reading CTD Sensor is fully independently developed by our company, with complete intellectual property rights and multiple patents. The localization rate of core components is 100%. Our company possesses a full suite of temperature, pressure, and salinity experimental facilities and equipment, capable of supporting the entire instrument lifecycle from design, production, and calibration to testing and maintenance, providing sufficient assurance for the quality and reliability of the sensor.
