Sentinel LPC 528 – Benchtop Pressure or Flow Leak Tester

The LPC 528 leak test instrument is characterized by excellent measuring accuracy, simple, intuitive operation, and durability. It is the benchtop version of the Sentinel C28 with the difference that it can be delivered as either a pressure decay/differential pressure decay tester or a mass flow test instrument.

LPC 528 Leak Testing Technologies and Highlights 

The Sentinel LPC 528 is a highly versatile, single-channel benchtop instrument supplying accurate and repeatable measurement in a proven, standard platform. It is designed to meet many basic test requirements using multiple test types with pressure, vacuum, or flow testing options. The LPC 528 can execute single or up to two linked tests in a user-programmed sequence or be easily integrated with a PLC. Combined with its ability to control up to 2 independent  tooling motions, a single instrument can control the operations of many simple test fixtures for a cost-effective  approach to benchtop testing.
