Where Gamma Immunity and Sensitivity Meet


Where Gamma Immunity and Sensitivity Meet

The Vertex50 is the smallest and lightest 50nm liquid particle counter on the market. The Vertex50 has the lowest zero count levels, has integrated manual flow control and incorporates TFT Touch Screen to simplify the user interface and offer an improved local user experience. Based on state-of-the-art technology, it is backed by a two-year warranty and international support.

Gamma immunity

Lighthouse Worldwide Solutions advanced photodetector technology allowed us to improve the optical signal to noise and lower gamma-ray interference 20 times. This means if your particle counter is reporting counts there are detectable particle counts in your ultra-pure water system.

Count subtraction is not used since we have the lowest false count rate in the industry. The Vertex50 reports the counts as soon as they come in, without waiting for an arbitrary value to be reached before the counter recognizes the particle counts.

Early Detection

With early detection comes the Vertex50s proven clean-up time after an event; the Vertex50 returns to baseline counts within 120 seconds after a particle event.
