Reverse Osmosis Monitor Model 2450 from Lakewood Instruments

Model 2450 Reverse Osmosis Monitor

Reverse,Osmosis,Monitor,Model 2450,Lakewood,Instruments The Model 2450 uses LonWorks^® Technology which is the latest in microprocessor capability that gives the user the highest level of application flexibility.

A large illuminated graphics screen, multiple inputs and very easy setup with easy field upgrades characterize this new technology.

Water meters and sensors are purchased separately.

Features

Uses 2-electrode conductivity sensor with ¾ inch MNPT process connection.
Uses differential pH sensor with ¾ inch MNPT process connection.
Two watermeter inputs for Permeate and Concentrate flow rates.
RS232 output for remote monitoring, control and data acquisition (-RS2L).
4-20 mA output for (-35L, select any four):

     pH, conductivity, temperature
     concentrate flow,
     permeate flow,
     percent recovery.

Input for CIP lockout.
System run timer.
Five (5) Count down timers

     Lubrication interval
