The reflective Glo-Gauge from McDaniel Controls was designed to allow greater visibility in the light of day, or, from far away in the darkness of night.
A pointer appears the standard black colour, but it has been given a ‘retro-reflective’ enhancement which reflects silver when illuminated by a flashlight held at eye level.
This allows an operator to easily see and determine if gauge pressure is in the safe operating zone specific for a specific process. Operators can customise each ‘safe operating zone’ simply by turning up tabs located outside the gauge lens face. These tabs are given ‘green retro-reflective enhancements’ and allow many different types of operating pressure zones to be indicated. Min/Max zones can be shown with just two tabs down, set apart at any desirable range spans, or, all the way apart for more relaxed operating zones.
Additionally, with just a few seconds charge from a flashlight, the gauge dial will glow-in-the-dark in low-light conditions to allow operators and technicians to monitor pressure readings while performing their maintenance tasks nearby.
