The Rettberg Water Flow Monitor LWW20 is engineered to safeguard laboratory equipment by monitoring coolant water flow. Equipped with a dual platinum electrode sensor housed in 3.3 borosilicate glass, it detects cooling water shortages and automatically shuts off connected devices, such as heaters used in solvent distillation systems. The system emits both optical and acoustic alarms upon detection of insufficient water flow.
Note: Supplied without the stand and accessories shown.
