Palmer Circular Chart Recorders are durable, fully mechanical units with a low maintenance design. Housed in a Pelican® brand case and available in 8 inch and 12 inch chart sizes, these recorders are lightweight and easy to carry.

Exterior stainless steel hardware and padlock protectors. Internals are all stainless steel - corrosion resistant with micro-adjustable wire linkage.
