VMP-250-IR Turbulence meter
VMP-250-IR、VMP-250-RT
The turbulent microstructure is one of the most important items in the understanding of the physical mechanisms of global scale, such as small scale underwater phenomena such as plankton. VMP-250 It is a falling type turbulence measurement profiler focused on the coastal zone. By installing "kit for raising observation" which can be attached and removed easily, it is possible to change to the rising type without opening the pressure resistant case in the field. Air weight 10 kg So it is easy to carry out transportation. In addition to the internal recording type, the real time measurement type is lineup (optional). Additional sensors such as chlorophyll turbidimeter can be customized according to your needs.
