Designed with long-term immersion in mind, this unit is waterproof to a depth of 500m, making it ideal for environmental monitoring in rivers and oceans.
The high visibility yellow case has an attachment point that can be used to secure the logger in position.
The lid can be removed to enable user-replacement of the battery.
Data is downloaded to the computer via a USB or serial download pad. This ‘wireless connection’ eliminates the need for sockets with waterproof caps which can easily be lost or forgotten.
For depths greater than 500m see ACS-0001-PK.
