Giving away 4 'Weston Cell' voltage references (Patreon)

which have been kept still and at 30°C +/-0.1 for months PLUS measurement results from my best voltmeters. Applications in the comments please, most hearts next Sunday win!

I want to make some room in this 'oven' for more modern voltage references and maybe other stuff. The weston cells will have to settle down at ideally 30°C after turbulent shipping, but they don't take lasting damage from overturning etc.

Here's a tour of that mystery metrology oven if you haven't seen it already: https://www.youtube.com/watch?v=PXc1EvcVOTo
