We have replaced the CS505 with the new CS506 Fuel Moisture Sensor. The CS506 uses the proven technology of the CS616 reflectometer to measure the moisture content of the 26601 10-hour Fuel Moisture Stick. Improvements over the CS505 include more-accurate measurements and more robust stainless-steel strips used to attach the fuel-moisture stick to the CS506 electronics. In the field, the CS506 is mounted with the CS205/107 fuel temperature sensor via the 26817 mounting stake.
