ShowerGuard Coating Detector

Quickly Identify ShowerGuard® Coatings in Production or at Installation

Guardian ShowerGuard® glass protects itself from corrosion and hard water buildup. ShowerGuard® is not coated on both sides of the glass. Therefore, installers can use the RD1661 meter to verify the ShowerGuard® coated surface is on the interior of the enclosure.

Prevent the loss of time and money in repairing an incorrect installation, and protect your reputation by doing a professional job. You can also use the meter to test the glass in front of your customers. This assures them that the glass is installed properly.

OPTO-CLEAN Technology Ensures Accurate Readings

If the OPTO-CLEAN software detects the build-up of dirt on the meter's lens, that could affect the accuracy of the measurement.  The meter displays a warning instructing the user to clean the lens. The warning stops once the lens is cleaned, so the operator knows the meter is working properly.

Easy Field Calibration Prevents Downtime

Under normal conditions, the meter rarely requires calibration. If necessary, the meter can easily be calibrated in the field. Error protection is built-in to confirm that a valid calibration has occurred. Typically, there is no need to send the meter back to the factory for calibration. This saves money and prevents downtime.
