W600 copper/nickel controller

(For electroless plating)

W600 controllers are value-priced mid-level copper/nickel controllers that provide reliable, flexible and powerful control for the electroless plating process. They measure the Copper, Nickel, and pH plus ORP, conductivity, or any sensor with a 4-20 mA signal.
Manufactured by: Walchem Corporation, USA

      Technical Details 
  • Copper: 0.10 to 99 g/l (varies with the chemical being measured), 0.10 to 5.50 g/l typical for electroless copper
  • Nickel: 0.10 to 25 g/l (varies with the chemical being measured)
  • 0.01 cell contacting conductivity: 0-300 μS/cm
  • 0.1 cell contacting conductivity: 0-3,000 μS/cm
  • 1.0 cell contacting conductivity: 0-30,000 μS/cm
  • 10.0 cell contacting conductivity: 0-300,000 μS/cm
  • pH: -2 to 16
  • ORP: -1500 to 1500 mV
  • Disinfection sensors: -2000 to 1500 mV/0 to 2 ppm, to 0 to 20,000 ppm
  • Electrodeless conductivity: 500 to 2,000,000 μS/cm
  •   Applications 
  • Electroplating
  • Electroless plating alkaline cleaners
  • Wastewater treatment
  • RO systems

  • Printed circuit board
  • Fume scrubbers
  •   Key Features 
  • Large touchscreen display with icon based programming makes setup easy
  • Economical wall-mount package for easy installation
  • Two sensor input slots provide extraordinarily flexibility; the same controller can be used with almost any type of sensor needed
  • Copper or Nickel plus pH
  • Dual analog inputs for any 4-20 mA transmitter
  • Universal analytical sensor card for pH/ORP, conductivity or disinfection
  • Combination analog input and analytical sensor input
  • Two virtual inputs that are calculated from two real inputs or one input and a constant
  • Multiple language support allows simple setup almost anywhere in the world
  • Six control outputs allow the controller to be used in a range of applications
  • Complete flexibility in the function of each relay
  • On/off set point
  • Plating control (on/off with totalising as metal turnovers)
  • Plating follow (activate with another relay)
  • Time proportional control
  • Proportional control (when purchased with 4-20mA or pulse solid-state up to outputs)
  • In-range or out-of-range activation
  • Probe wash
  • Flow timer
  • Alarm
  • Spike set point
  • Lead/lag control of up to 6 relays
  • On-screen and web page graphing of sensor values and control output status
  • Data logging
  • Email alarm messages, datalog, graphs, or system summary reports
  • Ethernet option for remote access via the Internet, LAN or Modbus/TCP
  • Copper/nickel controller helps maintain optimum operating limits within the process at all times with minimal manual intervention
  • Two sensor input slots provide extraordinary flexibility; the same controller can be used with almost any type of sensor needed
