G'Day MrsRadio,
He wouldn't take any notice of me so,
The most reliable, accurate and repeatable scales are the Beam Balance.
You've probably seen the old style platform scales in the providores aka Rural Merchants.
In fact our local Hospital has one you stand on and another that you sit in.
I usually sneer at their bathroom scale when they are trying to measure intake and exhaust.
The Spring type used domestically are notoriously inaccurate, especially with temperature variations.
There are pressure cell types used for mobile operations by the RTA etc., but have never gone into their efficiency, probably quite good in the heavy vehicle range.
Kindest Regards, " The Druid ".
