ES-300-G Electronic Sightglass

Description:

The ES-300-G Electronic Sightglass gives the AC service technician a real time, non-invasive look inside a refrigerant system. It is an ideal time-saving troubleshooting tool for quickly checking the AC system’s charge level and also for detecting defective AC components without the need to connect AC hoses and gauges.

Using ultrasonic technology, the ES-300-G responds and displays virtually in-sync with an actual sight glass as refrigerant changes state from liquid- to a liquid/gas mixture- to a gas. The graphic LCD displays a simulated cross section of the refrigerant tubing with animated circles (simulating bubbles) continually sweeping horizontally across the screen through the tubing- similar to an actual sight glass.

This valuable tool allows the professional AC technician to conduct both preventive maintenance and to quickly diagnose difficult service issues without opening up the system.
