The Holman Rain Gauge Wedge measures rainfall in millimetres over a set period, usually 24 hours. The top of the gauge has a larger surface area that tapers at the base of the wedge. The measurements are graduated with greater spacing between increments which allows for improved accuracy when measuring small amounts.
