The standard instrument for the measurement of rainfall is the 203mm (8 inch) rain gauge. This is essentially a circular funnel with a diameter of 203mm which collects the rain into a graduated and calibrated cylinder. The measuring cylinder can record up to 25mm of precipitation.
Most rain gauges generally measure the precipitation in millimetres equivalent to litres per square metre. The level of rainfall is sometimes reported as inches or centimetres. Rain gauge amounts are read either manually or by automatic weather station (AWS).

Neutralization is a type of chemical reaction in which a strong acid and strong base react with each other to form water and salt. Heartburn, as well as an acidic stomach due to eating too much spicy food, can be relieved by taking an antacid. The antacid is alkaline/basic and helps neutralize the stomach's acidic environment. You may have used medicine to ease your heartburn via the process of neutralization.
When acid and base react with each other to produce salt and water then such reaction is known as neutralisation reaction.
