The Petersen 938-96 Series Deflection Gauge with Aluminum Fins is a crucial tool for testing flexible sewer pipes for out-of-roundness or deflection, meeting ASTM specifications D3034 and F679. Designed for optimal performance, this gauge features a nine-arm design that ensures accurate testing without getting hung up by debris. Lightweight and corrosion-resistant, it can be assembled without tools and fits through standard manholes, making it versatile and field-verifiable. The aluminum fins provide stability and prevent tipping in the line, while the open design allows easy gravel and debris pass-through, maintaining testing accuracy.
