Sure, other manufacturers may say they test every nozzle. We know better and so should you. Only Monarch invests the time and money to perform 100% testing. That means each and every nozzle we make without exception. Its simply impossible to buy a Monarch nozzle that hasnt been tested and passed by our testing experts. Our tests include: 1. Flow Rate/Capacity. One by one, nozzle tips are tested at 100psi against calibrated matter samples. Flow must register within strict limits. 2. Spray Angle. Our testers check every nozzle to be certain its spray angle is within tolerance. Whether 30 or 90 or any angle in between is called for, Monarch nozzles meet all burner manufacturers recommendations. 3. Spray Balance. The nozzle is rotated 360 to be observed from every direction. Testers assure that the spray is symmetrical about its axis. 4. Spray Quality. A high intensity light is used to illuminate the spray. If shadows or streaks are observed, if there is a speck of dirt or surface defect at the orifice...that nozzle is rejected. 5. High Pressure Flutter. Pressure is boosted to 150 psi to magnify any defect and to be certain there is no pulsation or flutter that might otherwise escape detection. If our nozzles are perfect at both 100 and 150 psi, you can be certain they will perform for you.
