Is it water proof?
By Ryan C.
Answer QuestionYes, these A/F meters are built to JIS D 0203 S2 heavy water spray standards making them suitable for use on motorcycles and ATVs. For this test, the meter is subjected to heavy water spray for one hour at a minimum flow rate of 39.2 liters per minute. They're not meant to be submerged, however, so it's probably not a good idea for use on watercraft.
