The Vertex Series from Lighthouse Worldwide Solutions redefines performance in liquid particle counting. Available in two models — the Vertex 50 and Vertex 100 — this line delivers unparalleled detection sensitivity and compact precision for ultrapure water applications. The Vertex 50 is the smallest and lightest 50 nm liquid particle counter on the market, featuring the industry’s lowest zero count levels and integrated manual flow control. The Vertex 100, designed for 100 nm sensitivity, maintains the same compact footprint while setting a new benchmark for ultraclean monitoring at larger channel sizes. Gamma Immunity Lighthouse’s advanced photodetector technology has reduced optical noise and minimized gamma-ray interference twentyfold, ensuring the detection of only true particle counts in your ultrapure water system. Count subtraction is not required because Lighthouse instruments achieve the lowest false count rates in the industry. Both the Vertex 50 and Vertex 100 report counts in real time—without delay—providing reliable, immediate results. Early Detection and Fast Recovery The Vertex 50 and Vertex 100 are designed for rapid response. After a contamination event, each system returns to baseline levels within approximately 120 seconds, supporting early detection and quick recovery in critical water systems. Vertex50 Key Features: Channel sizes: 50nm, 100nm, 150nm, 200nm Four channels of simultaneous count data 100 mL per minute flow rate Built-in 3.5” color touch screen display 316L stainless steel construction Ethernet, RS485 Modbus Serial, 4-20mA NEMA style enclosure Integrated manual flow control Interfaces with existing building automation and facility management systems
