Refrigerant Electronic Sightglass
The sightglass "sees" into the refrigerant tubing by means of ultrasonics. Two sensors are used; one for transmitting and one for receiving. These sensors are in the form of clamps which attach to any metallic refrigeration tubing. An audible beeping sound quickens as bubbles or floodback are sensed, and a row of LED lght, simulating bubble movement in the tubing.
Features: Minimizes refrigerant charge for maximum cooling. Operates on any metal tubing. Four foot cord. Operates through use of ultrasonics. Eliminates the need for an optical sight glass. Checks for refrigerant floodback. Built into ABS carrying case. One Year Warranty.
Specifications: Operating Temperature - 32° to 125°F (0° to 52°C). Power Supply - One, 9V battery. Battery Life - 60 hours (alkaline). Response Time - Instantaneous. Probe/Cord Length - 48" (1.2 m). Dimensions - 8.7" x 7" x 2" (22cm x 18cm x 5cm). Weight - 1.4 lbs. (636 g).
