3/8" sight glass
ONE INDICATOR for all REFRIGERANTS - provides a true moisture indication for Refrigerant 12, 134a, 22, 404A, 407C, 410A, 502 or 507.
RELIABLE and ACCURATELY CALIBRATED COLOR CHANGE POINTS - in parts per million of moisture for each refrigerant.
REPLACEABLE INDICATOR ELEMENT - the color indicator paper can be changed on fused glass models manufactured since 1984 without removing the See•All from the line.
INDICATOR PROTECTED from DISCOLORATION and DIRT - by a filter pad and screen. This prevents washing of the indicator by the refrigerant and protects it from system contamination and turbulence.
COLOR CHANGES ARE EASILY DISTINGUISHED and REVERSIBLE - indicator colors differ so widely between the wet and dry condition, there is no possibility of confusion. Colors reverse as often as moisture concentration in the system changes.
LARGE FULL VIEW SIGHT GLASS - extra large crystal clear sight glass for viewing the refrigerant. Bubbles indicate a shortage of refrigerant or a restriction in the liquid line.
DISASSEMBLY FOR INSTALLATION IS UNNECESSARY - with extended fittings on small size solder models. See•Alls are easy to braze.
PLASTIC CAP - is supplied with See•All to keep the glass free from dust, dirt and grease.
