Power
optek inline photometric control can increase the efficiency of electric generating stations whether coal-fired, hydro powered or nuclear. Realtime monitoring can also provide protection against accidental environmental emissions.
optek photometers can detect very low ppm levels of lube oil in water to warn plant operators of seal leakage or seal failures. Instantaneous detection of a seal leakage or failure can prevent machine failure and damage caused by water leakage. Under adverse conditions, carryover of lube oil into the cooling water may occur and in turn is introduced to the environment. Online monitoring also means continuous measurements and history can be captured.
optek photometric analyzers can assist in reducing outage time and avoid a fall-off in energy production. Low installation cost, low costs of ownership, plus maintenance cost makes optek instruments the right choice for profitable power generation applications.

Galvanic
Rigid quality standards and the ever increasing need to optimize chemical use and improve process efficiency forces many electroplaters to seek a higher level of automation and control as a key to improving their process and increasing profits.
Maintaining and controlling plating bath chemistry is the key to a consistent quality finish. The electroplater can improve and automate the plating process by measuring and maintaining solution concentrations automatically using real-time, repeatable inline measurements with optek process photometers.
optek photometric analyzers measure the concentration of metals, suspended solids, undissolved salts, and other process constituents in the plating process, precisely and reliably. optek instruments provide operators with real time data and alarms, helping to avoid any process upsets.
In closed-loop control, the real-time analysis can be used to automatically adjust the bath chemistry during the process cycle. By installing optek photometric sensors in strategic locations in the process, the electroplater can greatly improve batch to batch quality, reduce the number of reject parts, improve chemical and effluent management and drastically reduce sampling and lab analysis.

Automakers depend upon efficient process control to keep manufacturing costs down. Real time photometric monitoring of paint, adhesives, flux and other chemicals enables automakers to extend equipment life, verify filter performance, and detect trace contaminants in the waste stream.
optek process photometry is valuable in various aluminum brazing operations, such as the manufacture of automotive radiators, condensers, heater cores and charge air coolers. By using optek photometers to monitor the flux consistency directly at the point of delivery or in the flux tank using a photometric probe, the flux consistency can be maintained in real time. This innovative method provides improved surface treatment resulting in optimal brazing and greatly reduced scrap and rework costs.
Real time optek photometry provides cost-saving control solutions for many other critical processes as well. Simple to install and easy to maintain, optek instruments will improve process control, improve quality and improve profits.
