Lambrecht rain weighing gauge [e]

This Lambrecht weighing gauge is a precision instrument for official and technical observation . The weighing system provides a resolution in the precipitation measurement of 0.001mm .
The mouth of the rain gauge follows the official standards of 200cm2 , just like the totalizing Hellmann rain gauges. The advantage of a digital rain gauge of these characteristics is that it has no limit to the measurement of rain and can quantify rainfall from 0.005mm to infinity .
It is made of metal, completely weather resistant and stainless. There is the option of adding metal spikes to prevent the entry of birds. It is recommended to place on a solid support, well fixed and free of any obstacles.
It has two options, unheated and heated . The heated option is useful for cold or mountain areas, where much of the winter precipitation is from snow . In traditional rain gauges, solid precipitation presents many problems for measurement, the traditional heated rain gauge solves these drawbacks.
The Lambrecht [e] rain rain gauge incorporates an output for connection to Lambrecht dataloggers (not included) (digital output) and analog output for external supply 0/4 ... 20mA (0 ... 2.5 / 5V).
