General Description
The TE525 series tipping bucket rain gauges are manufactured by Texas Electronics. Both the
TE525WS and TE525 measure in 0.01 inch increments; the TE525M measures in 0.1 mm increments.
These gauges funnel 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.
The TE525WS and TE525 are compatible with Campbell Scientific's CS705
Snowfall Conversion Adapter which allows you to measure the water content of snow. The TE525
requires a recalibration when the CS705 is added or removed; the TE525WS does not. The TE525M
is not compatible with the CS705. For more information about the CS705, refer to the CS705
product literature.

approximately 135 ms. |
Calibration/Cleaning Frequency:
| Sensor is factory calibrated and should not require field calibration. Debris filters,
funnel, and bucket reservoirs should be kept clean. |

| Cable: |
2-conductor, shielded cable, length must be specified when ordering. |
NOTE: The black outer jacket of the cable is Santoprene® rubber. This compound was
chosen for its resistance to temperature extremes, moisture, and UV degradation. However,
this jacket will support combustion in air. It is rated as slow burning when tested according
to U.L. 94 H.B. and will pass FMVSS302. Local fire codes may preclude its use inside buildings.
