N-LF420 0-50µS conductivity meter with 4-20mA output, LED display and 3/4 inch screw-in thread

Product number: 880630
Product information "N-LF420 0-50µS conductivity meter with 4-20mA output, LED display and 3/4 inch screw-in thread"

High-quality conductivity meter with a 4-20mA signal output for forwarding the measured value to a higher-level control system, for example. The measurement is temperature compensated and therefore offers you an accurate measurement result. Also here we have the possibility to offer you an individual design regarding the connection, the LEDs including the measuring range up to a private label. 

Due to the acrylic glass cover used, the light of the LEDs is widely scattered and the current LED status can be seen from a distance in darker rooms. 

Quality Made in Germany.

Standard LED configuration (1 green LED, 1 red LED):
<20 µS/cm = green
>20 µS/cm to <40µS/cm = green/red flashing  
>40 µS/cm = red
