WDP310-14N, Walchem pH/ORP Controller (WDP310-14N)

The Walchem WDP310-14N 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:

4 powered relay outputs (for on/off control, alarm or probe wash) and 1 powered dedicated alarm relay, 120 VAC, pre-wired with 6” pigtails, single isolated analog (4-20 mA) output, no electrode

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.
