Overview
The TE525, manufactured by Texas Electronics, has a 6 in. orifice and measures rainfall in 0.01 in. increments. It is compatible with all Campbell Scientific data loggers, and it is widely used in environmental monitoring applications.
Technical Description
The TE525 funnels precipitation into a bucket mechanism that tips when filled to its 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 our data loggers.
Benefits
- Accuracy is ±1 percent at rates up to 1 in./hr
- Compatible with most Campbell Scientific data loggers
- High precision—tips at 0.01-in. increments

Common Accessories
(6)CM270
Rain Gage Mounting Kit for the TE525, TE525MM, or TE525WS
The CM270 can be used to mount the sensor instead of the mounting that is included with the sensor.
Orderable260-953
Alter-Type Rain Gage Wind Screen
This wind screen consists of 32 leaves that hang freely and swing as the wind moves past them. The 260-953 helps minimize the affect of wind on the rain measurements.
OrderableCM300
23 in. Mounting Pole with Cap
The CM300 provides a 23-inch long pole for mounting the TE525. This pole can be embedded directly into a concrete foundation or used with a pedestal kit. Campbell Scientific offers a j-bolt pedestal kit for permanent installations; a short leg kit for many temporary installations and many situations where it is impractical to use a concrete foundation; and a long leg kit for locations where the feet cannot be secured (e.g., pole sitting on a roof) or for areas that experience high wind speeds.
OrderableCM305
47 in. Mounting Pole with Cap
The CM305 provides a 47-inch long pole for mounting the TE525. This pole can be embedded directly into a concrete foundation or used with a pedestal kit. Campbell Scientific offers a j-bolt pedestal kit for permanent installations; a short leg kit for many temporary installations and many situations where it is impractical to use a concrete foundation; and a long leg kit for locations where the feet cannot be secured (e.g., pole sitting on a roof) or for areas that experience high wind speeds.
OrderableCM310
56 in. Mounting Pole with Cap
The CM310 provides a 56-inch long pole for mounting the TE525. This pole can be embedded directly into a concrete foundation or used with a pedestal kit. Campbell Scientific offers a j-bolt pedestal kit for permanent installations; a short leg kit for many temporary installations and many situations where it is impractical to use a concrete foundation; and a long leg kit for locations where the feet cannot be secured (e.g., pole sitting on a roof) or for areas that experience high wind speeds.
Orderable39112
DIN Rail Terminal Kit with 1 Terminal and 3 Wires
The 39112 provides the needed DIN rail terminals, separator, and wires to connect any product to a data logger or other peripheral that requires three wires for connection. This kit provides the following wires: black, white, and clear. The color-coding of these wires matches the wire coloring of the product for ease in connection, maintenance, and troubleshooting.

Replacement Parts
(5)13818
Replacement Screen and Snap Ring for TE525
The 13818 is a user-replaceable screen. Its 6" diameter fits at the base of the funnel.
Orderable5603
Replacement Reed Switch with Terminal Lugs for TE525-Series Rain Gages
The 5603 is for newer TE525-series rain gages that have the reed switch enclosed in a black plastic housing. A screwdriver is required to replace the switch and rewire the connections. This replacement can generally be accomplished by users who wish to perform the replacement themselves. Alternatively, an RMA may be requested from Campbell Scientific, and the switch can be replaced by one of our technicians; this option may be more viable if the rain gage is scheduled to undergo factory recalibration at the same time.
Orderable30272
Replacement Reed Switch without Terminal Lugs for TE525-series
The 30272 is similar to the 5603 (see above), but it does not include terminal lugs. Users can often perform the replacement themselves. Alternatively, an RMA may be requested from Campbell Scientific and the switch can be replaced by one of our technicians. If your TE525MM rain gage has a reed switch that is encapsulated in glass with a red potting compound on either end of the glass tube, the rain gage should be returned to Campbell Scientific for replacement of both the reed switch and the tipping bucket mechanism.
Orderable30278
Replacement Funnel/Collector with Screen and Snap Ring for TE525
The 30278 provides a funnel/collector and a screen with snap ring for the TE525.
Orderable33735
Low-Profile Stainless-Steel #8-32 x 0.375 Knurled-Head Thumb Screw
The 33735 may be ordered as a replacement part if a thumb screw is lost or damaged.

Compatibility
Mounting
The TE525 rain gage mounts to a CM300-series Mounting Pole or a user-supplied 1.5-in. IPS pole. Several pedestal options are available to secure a CM300-series pole to the ground (see Ordering Information). Accurate measurements require the gage to be level.
Snowfall Adapter
The TE525 cannot be directly used with our CS705 rainfall adapter. However, the CS705 is compatible with the TE525WS, and the TE525 can be converted to a TE525WS by returning it to Campbell Scientific (requires an RMA).
Wind Screen
Campbell Scientific offers the 260-953 Wind Screen to help minimize the effect of wind on the rain measurements. This wind screen consists of 32 leaves that hang freely and swing as the wind moves past them.
