Product Description

The Questtec Solutions See-Level™ LED Illuminator for hazardous locations utilizes the latest technology to provide brilliant green back lighting to any process gauge. Innovative circuitry allows for the use of an individual light source every ½” along the length of any gauge. With a life span of over 100,000 hours each, the LED’s last 200 times longer than incandescent bulbs. Even in the event of an individual lamp failure, the design provides lighting overlap ensuring that the fluid level is always illuminated. All of this is accomplished with a meager 5 watts of power usage. Through the use of new attachment techniques, the See-Level™ Illuminator readily mounts to any brand of existing or new process gauges in a matter of minutes without the loosening of any cover bolting. Mounting requires no special tools or modifications to the existing structure. Set it up, attach the power and go! It’s that easy. The modular design allows for a single illuminator to be manufactured to your specific visible length eliminating the labor involved in mounting and wiring multiple illuminators.
