SEVYTEST™ GAUGE
Some of the Sevylor ® products are equipped with a Sevytest™
gauge. The Sevytest™ device is a pressure gauge, not an infl ation
gauge. The Sevytest™ gauge is found on the side wall, inside the
main chamber(s). The purpose is to show you when to let some air
out after the pressure has increased due to temperature change.
The principle of the Sevytest™ gauge is based on the lengthening of
the PVC under the infl uence of pressure. Once the boat is properly
infl ated, note the position of the Sevytest™ indicator. Then periodical-
ly check the Sevytest™ gauge and let out enough air to keep the test
strip in the same general area. If the Sevytest™ indicator is in the “+”
zone, add pressure to the product. If the Sevytest™ indicator is in “-”
zone, release pressure from the product.
