CS725 Snow Water Equivalency Sensor
14. Maintenance and Assembly
There is no recommended user maintenance required for the CS725.
We do not recommend disassembling the CS725 for any
reason. The CS725 instrument is very complex and is
intended to be repaired or maintained only by factory
trained personnel. CAUTION
It is recommended that the CS725 be calibrated every seven years. The reason
for the timeline is to ensure the CS725 gamma ray detector does not drift out of
specification.
The following diagrams demonstrate the internal makeup of the CS725. To
reduce drastic temperature gradients, the CS725 is filled with an advanced
insulating material known as Nanogel (see FIGURE 14-3, CS725 cutout view).
The manufacturer’s (Cabot Corporation) MSDS sheet should be consulted
prior to exposing the Nanogel insulation.
