Ponar Grab with Removable Windows

Advanced Sediment Collection with the Ponar PG Grab

A robust professional solution engineered for precision sampling of hard underwater bottoms, ensuring maximum penetration and sample integrity.

The Ponar PG Grab is a high-performance instrument specifically designed to master the challenges of sampling hard aquatic substrates such as sand, gravel, consolidated marl, and clay. Built to honor the complexity of underwater nature, this grab features a sophisticated pin-and-spring locking mechanism that guarantees a secure closure upon contact with the bed. Its design minimizes the "bow wave" effect during descent, preserving the delicate surface layer of the sediment and providing researchers with an undisturbed glimpse into the benthic environment.

Key Features

• Innovative pin-and-spring locking mechanism that triggers reliably upon bottom contact.
• Integrated arm weights designed to enhance penetration depth in highly consolidated sediments.
• Removable top windows equipped with 500-micron AISI 316 stainless steel mesh for precise sensor access.
• Rubber covers on inspection windows to prevent sample washout during retrieval.
• Constructed from premium AISI 316 stainless steel for exceptional durability in corrosive environments.
