An electronic scale includes: a scale body that has a top surface provided with a weighing tray on which an object to be weighed is to be laid and a display portion which displays a weight of the object to be weighed; and a lid member that is capable of closing the top surface of the scale body and that is capable of opening and closing. A camera that images the top surface of the scale body including the weighing tray and the display portion is provided on the lid member. Alternatively, the camera is provided on the top surface of the scale body and the lid member includes reflection means that reflects an image of the top surface of the scale body including the weighing tray and the display portion toward the camera when the lid member opens, on a surface of the lid member that faces the scale body. The electronic scale is capable of simultaneously imaging the object to be weighed and the displayed weight of the same and eliminates need for a special support structure to support the camera for imaging, and the top surface of the scale body can be closed when the electronic scale is not in use.

A communicating sterile scale is described suitable for automated use in animal cages. An upper module provides a weighing platform, electronics, upward facing wireless communication elements, a protecting skirt, and interface to a combined weight-bearing and electrical penetration element. A lower module provides a case, internal electronics, load cell, power source, sterile-sealed flexible complaint membrane and a combined weight bearing and electrical penetration element through the membrane. The upper and lower modules are easily separable for sterilization by immersion in a sterilizing fluid. The power source in the case may be charged through same electrical penetrating element. The membrane comprises a perimeter that is attached and sealed to the case, a penetration area penetrated by the rigid weight-bearing element, and an isolating compliance area. The skirt on upper module protects detritus from entering from below onto the membrane, while providing open-air movement. Upward facing narrow-beam communication elements provide association-free communication protocols.
