TE525MM-L Tipping Bucket Rain Gages

The TE525-series tipping bucket rain gages are manufactured by Texas Electronics. The TE525MM measures in 0.1 mm increments. The gage funnels precipitation into a bucket mechanism that tips when filled to a calibrated level. A magnet attached to the tipping mechanism actuates a switch as the bucket tips. The momentary switch closure is counted by the pulse-counting circuitry of Campbell Scientific dataloggers.
