The Milenco Precision Calibrated Ball Weight Gauge has been manufactured using unique materials so that its calibration remains accurate even after 1000 uses. Other Ball Weight Gauges can be up to 70 kilos out after 1000 uses.
Another improvement is that the scale is much clearer and goes up to 400 kilos and is accurate to within 8 kilos (as required by BS7961). Further improvements include the fact we made the Ball Weight Gauge the same height as your caravan, so you do not need to block it up to use it.
We know this Gauge costs a few pounds more, but you are getting real value for money and something that works correctly, exactly to the standard. We think this is far better than something that can be potentially dangerous, as you can end up with a low Ball Weight, which is the trend with the un-calibrated Ball Weight Gauges as the springs often soften with use especially those using piano wire.
The Camping and Caravan Club conducted a study on Ball Weight Gauges and found them to be inaccurate and unreliable. They then approached Milenco and asked if they could produce a Ball Weight Gauge to the standard BS7961, which was written in 2004. At this time no one had produced a conforming gauge to the standard.
We conducted studies on the available Ball Weight Gauges and at best found them only accurate to within 2% but more concerning is that we found these Ball Weight Gauges often become ridiculously inaccurate with use.
