Detailed Description

The CM240 may be attached to a CM300-series mounting pole, or to a user-supplied 1.5 IPS (1.9" OD, unthreaded) pipe. The pipe should be long enough to place the gage's orifice at a one-meter height. The pole or pipe can be placed directly into a concrete foundation, attached to a concrete foundation using j-bolts, or self-supported with legs. A concrete pad is recommended.


The CM240 is used with the TB4, TB4MM, CS700, CS700H, and 385 tipping bucket rain gages.
