For applications that require exact dosing of fluorescent
dye at precise intervals of time, such as for an oil pipeline or engine
plant assembly line operation, we offer solutions ranging from a simple
trigger gun syringe to metering pumps that can be programmed, configured
and calibrated to your specific application needs.
