Controller for electroless nickel baths / Controller for electroless copper baths Controller for electroless nickel baths Nickel controller with flow-through sensor Walchem's WNI Nickel Controllers are optoelectronic on-line analyzers that measure the actual concentration of nickel in solution.  The WNI410 is available as nickel-only, or with a pH control option which may be added in the field. Two separate pump outputs for nickel and reducer and another for pH are used, each of which is capable of totalizing either pump on-time, volume pumped, or metal turnovers. Integrated data logging is available to validate system performance. With a USB memory stick data and event logs that include nickel measurements, and relay status can be extracted. Download logs from the USB stick to a PC. Product features: Concentration Read in Units Selectable between grams per liter (g/L) or ounces per gallon (oz/gal). Backlit digital display also acts as a bar graph for a continuous "visual summar

Walchem's WDIS Series controller will reliably and economically control your water treatment disinfection process. The controller includes four standard sensor input options (free chlorine/bromine, chlorine dioxide, ozone and peracetic acid) or can be configured to use a variety of other types of disinfection sensors such as hydrogen peroxide or total chlorine. The WDIS Series controller takes the guesswork out of your disinfection process. The chemical concentration is continuously monitored and controlled to the precise range required for proper system control and regulatory compliance. Designed to be flexible and versatile, the WDIS series controller is the ideal solution for disinfection applications in cooling towers, food and beverage, drinking water, wastewater and swimming pools. Integrated datalogging is available to validate system performance. With a USB memory stick data and event logs that include disinfection sensor measurements and relay status can be extracted. Then

The WEC/WDEC410 Series Single and Dual Input Electrodeless Conductivity Controllers measure conductivity of a solution via an encapsulated, non-contacting sensor to control replenishment pumps and alarms. They may be installed in a variety of very harsh chemical control applications, including oily cleaner baths, chromates, rinse tanks, fume scrubbers and other concentrated chemicals up to a conductivity of 1000 mS/cm. Four conductivity ranges may be selected to configure the controller over a wide range of applications. Choice of measurement units is µS/cm, mS/cm, ppm and % concentration. The non-contacting, toroidal sensor technology is immune to thin coatings and the contamination and calibration problems that direct contacting sensors are prone to. Integrated datalogging is available to validate performance. With a USB memory stick data and event logs that include conductivity measurements, temperature and relay status can be extracted. Then download log files from the USB stick

 WPH webReady The pH/ORP on-line process controllers are designed for industrial, commercial, and municipal water treatment applications. The output configuration allows you to program up to four outputs in a variety of control modes. Select from on/off mechanical relays or pulse proportional control for direct connection to metering pumps. The easy-to-use menu format and pre-wired, pre-mounted panel system options make set-up and installation quick and simple. Integrated data logging is available to validate system performance. With a USB memory stick data and event logs that include electrode measurements, temperature and relay status can be extracted. Then download log files from the USB stick to a PC. Product features: Range of applications Select from pH or ORP measurements and from five output options. Use In-Range to control a solenoid valve to dump a batch treatment tank when measurement value is within limits, or program for Out-of-Range Alarm in waste treatment applica
