Overview

The CS505 Fuel Moisture Sensor was retired on September 22, 2009. It consists of an epoxy-encapsulated electronics package. It uses Time Domain Reflectometry Technology to measure the moisture content of the 10824 10-hour Fuel Moisture Stick. The 10824 is a USFS-specified, 10-hour, ponderosa-pine dowel that is purchased as a Common Accessory (see Ordering Info).

The "-L" on a product model indicates that the cable length is specified at the time of order.

Additional Compatibility Information

Fuel Temperature

The CS506 is typically measured alongside the CS205/107, which measures the fuel temperature.

Mounting

The 10974 Mounting Stake is often used to mount the CS505/10824 with the CS205/107. This stake places the probes twelve inches above the forest floor. Because the probes are mounted parallel to each other, shadowing is minimized. Cable ties are included for securing the cables to the side of the stake.
