Self-contained Temperature Salt Depth Sensor (Tutti CTD Recorder)
Tutti CTD recorder is a high-precision self-capacitance temperature-salt-depth sensor completely independently developed by the company. The company owns all intellectual property rights and has obtained a number of patents. The performance of the sensor is stable and reliable. At the same time, the company has a complete set of temperature, pressure, salinity experimental environment and equipment, which can support the entire life cycle of instruments from design, production, calibration, testing, maintenance, etc., and provide sufficient guarantee for the quality and reliability of temperature and salt depth sensors.


Product Description Tutti CTD recorder is a high-precision temperature, salinity and depth measurement sensor for deep-sea applications. It has the characteristics of high precision, small size and low power consumption. Under the premise of ensuring accurate measurement, the maximum sampling rate can reach 2Hz. The shell is made of titanium alloy material, which can withstand the corrosion of seawater for a long time, and can withstand the maximum water depth pressure of 7000 meters. Each core device is made with a unique process, and the localization rate is 100%.

Working Principle
It has been verified many times that the Tutti CTD recorder has ultra-high precision and stability. The temperature accuracy is ±0.002°C, the salinity is ±0.003mS/cm, and the pressure is ±0.05%F.S. Its electrical interface and communication method can be based on user needs.Tutti CTD recorder adopts ultra-low power consumption design. When the sampling interval is 15s, the sensor can work continuously for more than 1 year, and a 32GB SD card inside can fully meet the needs of users. Under the characteristics of maintaining low power consumption, the communication rate can reach 115200bps.
Advantage Characteristics
High measurement accuracy and excellent low power consumption Keeping the characteristics of ultra-low power consumption, the communication rate is adjustable from 9600 to 115200bps
Communication protocol and communication interface can be customized Internal storage space can hold 160M sampling information Sampling rate can be adjusted up to 2Hz
