Tide logger 


Tide logger (HY-CW1) is a tide gauge for nearshore or shallow waters, which can obtain two set of values in pressure (depth) and temperature at the same time. It is small, lightweight, easy to use, and can be deployed for long periods of time. It can do long-term monitor in tide level and temperature.

Dual sensor,

temperature & pressure

Diffusion silicon pressure core, temperature probe

Small in size, light in weight

Weight is only 318g, diameter is 34mm, and the length is 331mm

High strength and corrosion resistance

The shell is made of POM (Polyoxymethylene) material, which has high mechanical strength and rigidity, environmental resistance, and resistance to organic solvents
