Yesterday I spoke to Les at Durite about my concerns and today 29th May spoke to Mellisa who is sending an email to Les with directions to this page.
a) there is difficulty in viewing the thermometer liquid, being red doesn't help as that is also the background colour of the container shedding red light eveyrwhere. It appears as though the thermometer is skewed by some 20 to 30 degrees. It can't be adjusted :(
b) After my earlier conversation I noted the scale is high by about 2 points, to resolve that I cut a small strip off the removable scale insert to set it lower.
Here are images of the issue a)
1. I slipped a small peice of a plastic bag behind the thermometer to contrast the background and block any red relfection. You can see the red liquid is just about visible when looking directly at it.
2. When viewing from the right about 30° the liquid is clearly visible.
3. With the scale reinserted and looking at it straight on
4. With scale inserted and looking from 20°
