One Indicator for Refrigerants 12, 134a, 22, 404A, 502 and 507     The See-All Moisture and Liquid Indicator provides a true moisture indication for Refrigerants 12,134a, 22,404A, 502 and 507. The See-All is also suitable for Refrigerants 401A & B, 402 A & B, 408A and 409A. The dark green indicates dry and a bright yellow indicates wet. The one indicator avoids the confusion found in models with two elements. You cannot pick the wrong element when checking the moisture content of the system.       Reliable and Accurately Calibrated Colour Change Points     The See-All Moisture and Liquid Indicator is accurately calibrated in parts per million of moisture for each refrigerant. All moisture indicators change colour on the basis of relative saturation of the refrigerant. Therefore, liquid line temperature must be considered if an accurate calibration is to be obtained. A colour chart is part of the label, for easy comparison.       Colour Changes Are Easily Distinguished and Reverisble     The indicator's colour differs so widely between WET and DRY conditions that there is no possibility of confusion between the two. Colours will reverse as often as moisture concentration in the system changes.       Large Full View Sight Glass     The See-All Moisture and Liquid Indicator has an extra large crystal clear sight glass for viewing the refrigerant. Bubbles indicate a shortage of refrigerant or a restriction in the liquid line.       Indicator Protected from Discolouration and Dirt     The indicator is protected by a filter pad and screen. This prevents washing of the indicator by the refrigerant and protects it from system contamination and turbulence.       Replaceable Indicator Element     The colour indicator paper can be changed on the new fused glass models without removing the See-All from the line. Replacement is through the bottom (see SA-14SU below). Request the K-SA-4 Kit.       Disassembly of the Smaller Sizes Not Required     The extended steel fittings on solder models in the smaller sizes make it unnecessary to disassemble for installation since steel conducts only one eighth as much heat as copper.       Double Duty Plastic Cap     A DOUBLE DUTY PLASTIC CAP is supplied to keep the glass free from dust, dirt, and grease. It also permits the service engineer to use his own discretion concerning instructions to his customers on observing the See-All Moisture and Liquid Indicator.
