WEC410-5NNN, Walchem Conductivity Controller (WEC410-5NNN)
The Walchem WEC410-5NNN controller is now obsolete and the closest equivalent is the WCN600HSNNN-NN controller. The new WCN600 series has upgraded features; for reference, here is the description of the old model:
hardwired, cable glands, no 4-20 mA output, no sensor
Electrodes are available separately. Choose the new model on our WCN600HSNNN-NN page or select a model more suited to your needs from the WCN600 Series Conductivity Controller or the more basic W100 Series Conductivity Controller.
