Install Ballast Weight

    Proper ballast weight is essential to prevent buoy overturning. Carefully consider the site-specific ballast requirements prior to deployment. A 25 lb. ballast weight is available for installation to the bottom of the instrument cage for additional balance. 1. Begin installation by inserting the 9-3/4” threaded rod section through the ballast weight and bottom of the […]

    Batteries, Solar, and AC Power

    Two common questions that come up when deploying environmental monitoring systems are “How much power do I need?” and “What type of power do I need?” These questions arise because an under-designed power supply could result in data loss, and an over-designed power supply could add an enormous cost to the system and require a considerable […]

    Primary and Secondary Cell Batteries

    Overview Typically, environmental monitoring systems are battery-operated. This is because they are usually in remote locations or need to record data when other forms of power are unavailable. The focus of this article is on battery systems, specifically alkaline batteries and other cell-type batteries. Required Battery Capacity The first step in determining an appropriate battery […]
