The range of applications comprises the measuring of chemical products for civil and industrial waters, boiler water conditioning, potabilization, etc.
Lambro Idrodepurazione Division offers units for preparation, storage and measuring of many chemical products in solution:

- standard measuring stations M1 series for constant capacities
- proportional measuring stations M1P for variable capacities 

Adjustment and functioning, both for the normal and proportional series are extremely simple. Particular attention has been payed to fluid disinfection where electrical energy availability problems may occurr.

Lambro Idrodepurazione Division set up two series of hypochlorite gravity proportioners for use in water potabilization and depuration, which work without electrical energy:

- DDP Series standard gravity proportioners
- CLOR-SEM Series proportional gravity proportioners

Gravity proportioners don’t need any maintenance, but a quarterly washing, and work without any hazard of breaking or obstruction.
