Salinometer
Alfa Lavel
New product
The Alfa Laval Salinometer DS-20 is a marine salinity monitoring unit used for measuring and alarming salt concentration in freshwater generator, evaporator, boiler water, condensate and engine room water systems. Correct salinity control is extremely important onboard ships because high salt content can damage boilers, contaminate freshwater production and reduce the efficiency of evaporator systems.
This unit provides clear PPM indication and alarm functions, allowing marine engineers to monitor water quality and take quick action when salinity exceeds the acceptable level. The DS-20 is suitable for shipboard environments where reliable monitoring, simple operation and easy troubleshooting are required.
SM MARINE SERVICE™ supplies Alfa Laval Salinometer DS-20 units as New Equipment, Used Equipment and Reconditioned Equipment depending on customer requirements and budget.
Alfa Laval Salinometer DS-20 Front View
Alfa Laval Salinometer DS-20 Wiring Diagram and Terminal Side
The DS-20 Salinometer continuously monitors the salinity level of water through a conductivity measuring arrangement. The front display provides PPM indication, while the alarm circuit activates when the salinity rises beyond the selected alarm setting.
From the supplied product images, the unit shows a PPM scale from 0 to 20, alarm indication, alarm set function, test function and secondary alarm on/off function. The side label also shows relay function wiring, making the unit easier for engineers to install, test and troubleshoot during maintenance.
Typical onboard use includes freshwater generator outlet monitoring, evaporator distillate monitoring, boiler feed water protection and condensate quality supervision.

Alfa Laval DS-20 Salinometer Display Panel
The DS-20 Salinometer is commonly used in shipboard water quality monitoring systems where high salinity may cause operational problems. In freshwater generators, it helps confirm that produced freshwater is within acceptable salinity limits. In boiler systems, it helps protect boiler feed water from salt contamination. In evaporator systems, it supports safe distillate monitoring.
Common vessel applications include:
