Profile: Koehler Scale, Inc. is a distributor of different types of scales. Our ​sine-wave viscometer measures viscosity by detecting the driving electric current necessary to resonate the two sensor plates at constant frequency of 30Hz and amplitude of less than 1mm high measurement accuracy. Our barrel/drum scales have optional ramps, portability kit and digital weight indicator. They are a multipurpose low profile floor scale which allows wheeled bins and drums to be easily pushed on and off. These floor scales have a weighing surface that is only an inch and a half off the ground, which allows operators to safely and effortlessly push loaded carts up onto the scale.
