When you are looking to take your environmental monitoring program to the next level, the ApexZ50 is your solution. The power of the ApexZ50 starts with the most complete system of self-diagnostics in the industry, an enclosure that is sealed, easy to wipe-down, and chemically compatible with all major cleaning solutions, and much more.


     Lighthouse is famous for re-defining particle counting when we launched our first products. Now the ApexZ50 is doing it again with features such as a handle with integrated status lights, an app for remote control and configuration, integrated WiFi and Bluetooth, 8-hour battery life with hot-swappable smart batteries, and a true multi-touch enabled display.


     The ApexZ50 is designed to be integrated into your environmental monitoring program. With the ability to wirelessly send data to your computer or server, the ApexZ50 can be used as a wireless real time sensor. Rooms and custom sample recipes can help to automate and simplify your monitoring routine. The ApexZ50 gives you various user and security levels, audit trails, and data tags that allow you to record things like batch and lot information, room status, or any other information you want associated with your particle counts. For large scale production facilities, we even offer custom integration and automation solutions.


     Contact your local Lighthouse representative and see for yourself where the ApexZ50 can take you.
