Flow sensors - Import export

The pressure regulator can be tightened by hand without the need for a spanner. It reduces the stored bottle pressure from max. 200bar (on request 300bar) to an outlet pressure which is adjusted at the flowmeter. The flowmeters are used to set the required flow in l/min. Important: The pressure regulator has a constant outlet pressure of 2.5bar which is necessary to protect the gas flow sensor of the orbital unit. Versions: — Special Argon Pressure Regulator with twin flowmeter, brass — Special Pressure Regulator with twin flowmeter for H2-gases, brass — Special Argon Pressure Regulator with triple flowmeter, brass Pressure regulators with different connections and for use with other gas types or nickel-plated version available on request.

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
