  • Replacement Weather Station Rain Gauge - Tipping Bucket Type 0.3mm Rain / pulse ()

    his tipping bucket rain gauge has a magnetic reed switch that closes momentarily each time the gauge measures 0.011" (0.2794 mm) of rain.

    The 9 foot (3 meter) cable terminates in an RJ11 modular plug, and can easily be extended using a common telephone extension cable.

    The gauge can be easily connected to an Arduino, Rapberry Pi, or any microcontroller. Commonly a pull-up resistor (4.7k ohms is typical) will be used to pull the input pin high, and the other side of the gauge's switch will be connected to ground, pulling the pin low each time the switch closes.

    Designed for general laboratory heating applications. Low-profile design conserves space and fits easily into most fume hoods. The front panel features easy-to-use controls that allow users to dial-in adjustments. Spill-resistant housing channels fluids away from the internal components. On the rear of the unit is a built-in support rod holder with locking knob.


    Microprocessor control regulates heat and brings samples to desired temperature quickly and accurately. Easy-to-read LED display shows set point temperature and provides repeatable and accurate results. For additional safety, a warning light is illuminated when heat is turned on. The warning light remains on until the top plate cools down. The overshoot protection function will automatically shut the unit down if the set temperature is exceeded by 10°C, or if the stirrer motor stops or fails. Built-in memory allows users to recall the last set temperature even after the unit has been turned off. A powerful, continuous-duty motor and magnet deliver dependable and reliable stirring for a long service life.


    Choose from models with a ceramic or aluminum top plate. Ceramic top plates feature an easy-to-clean, chemical-resistant, reflective white surface. Durable aluminum top plates provide a more even heating surface and will not crack or chip.
