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

Conductive Cooling Water Controllers / Toroidal Cooling Water Controllers  Conductive Cooling Water Controllers WCD410 All standard features are included, plus information management tools that enable you to deliver more effective service to your customers.

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

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

Why streaming current? The charge potential of particle surfaces of the solids in a disperse system plays an important part in water treatment procedure. Due to the unidirected charge of these particles, an approach is prevented. The particles are stabilized in its solution. A separation of these particles will be easier, if the surface charge can be reduced and the particles can form bigger flakes and bigger units. In order to control this process, it is important to measure the surface potential of the solids. What is streaming current? If you fix two electrodes in a pipe-line carrying a suspension, one in the centre and the other one near the pipe-line wall, you can measure a current. This is caused by the separation of the counter ions from the solids. The counter ions will be carried with the turbulent flow, and the solids tend to stick to the pipe-line wall by adsorption and by 'van-der-Waals' forces. The measured current is named current caused by flow or Streaming-Current.
