Nowadays, I have been working on frosting, defrosting and refrosting occuring at unit coolers. I need a sensetive scale to put under to test unit, so it must be like a rectangular platform. As my test products weight is about 30-100 kg including fan, the frost mass forming on unit cooler during test operations changes between 4 kg and 10 kg, therefore the scale has to be about 110 kg capacity. I would like to be grateful if you could share recommendation of a sensetive scale brand . Thank you in advance
Ergin,
Measuring a change of a few kg on a 100kg mass is not difficult.
For little outlay you can measure with gramme-level precision over that range.

If your equipment cannot be moved around easily, I would suspend it from a load cell and measure the load that way. You will be able to achieve accuracies of the order of one part in 10^3 quite easily.
