Compact CTD Sensor JES10mini

JES10mini is a small CTD sensor for observing salinity, temperature and depth in the sea. It is compact and lightweight, and can be cast simply using a fishing tackle.
It can be activated, set up, and read out data via Bluetooth communication. Furthermore, it has low power consumption and can be moored for up to one year.

Observable depth:: 200m (plastic) / 500m ・1,000m (SUS)

Observation items:: Electrical conductivity, water temperature, water depth

Communication method:: Bluetooth RS232 / 485 (optional)

Battery:: Lithium primary battery x 2

Size:: Length 173mm x Diameter 45mm

Weight:: 480g (plastic) / 800g (SUS)

Multipurpose (Compact) Observation Float (MOF)

MOF is a float that can automatically ascend and descend in the sea during observation. Equipped with a CTD sensor, it observes salinity, water temperature, and water depth. The observation data is automatically transmitted when the float is raised to the surface, and can be received on land. An optimal observation sequence can be constructed based on various purposes, such as observation depth and data acquisition frequency. The onboard sensors can be customized according to the application.

Observable depth:: 500m

Observation items:: Electrical conductivity, water temperature, water depth (standard)
Other observations in the past : Illuminance, dissolved oxygen, waves, FRRF

Communication method:: 2.4GHz wireless communication (for setting)
Iridium SBD communication (pelagic)
4G LTE communication (coastal)

Battery:: Lithium ion battery (for recharging) or
Lithium primary battery (for long-term observation)

Size / Weight:: Total length 940mm Weight 7.8kg

Uptime:: More than 1 year

Multipurpose (Compact) Observation Glider (MOG)

MOG is a compact, user-friendly float that can automatically ascend and descend in the sea during observation. Equipped with a CTD sensor, it observes salinity, water temperature, and depth in the sea.
The observation data is automatically transmitted when the float is raised to the surface, and can be received on land. An optimal observation sequence can be constructed based on various purposes, such as observation depth and data acquisition frequency. Further, the onboard sensors can be customized according to the application.
