If you're constantly weighing out a hot substance then, the short answer is yes. Normally the working temperature of an electronic scale is 5˚C - 35˚C. For our scales, we recommend 15ºC - 40ºC in the room. The normal brewing temperature of a filter coffee is usually between 92˚C - 98˚C. The prolonged exposure of the hot water and the scale can eschew the reading precision of the loading beam and possibly damage the components of the scale over a long or frequent amount of time. This is why we recommend using a heat absorbent pad, such as the one provided with your scale, so to help maintain the life and ability of your scale.
