WDP410-14NN, Walchem pH/ORP Controller (WDP410-14NN)

The Walchem WDP410-14NN controller is now obsolete and the closest equivalent is the WPH600PSSAN-NN controller. The new WPH600 series has upgraded features; for reference, here is the description of the old model:

pH/ORP controller, with 4 powered on/off relays & 1 powered dedicated alarm relay, 120 VAC, prewired, 6” pigtails to powered relays, single isolated analog (4-20 mA) output, no electrode, no USB

Choose the new model on our WPH600PSSAN-NN page or select a model more suited to your needs from the WPH600 series controller or one of the other pH controllers.
