The longevity and reliability of this 130-year old technology seems inconcievable today. And no spurious precision! 🤓 <a href="https://mastodon.scot/tags/InstrumentationDoneRight" class="mention hashtag" rel="nofollow noopener" target="_blank">#<span>InstrumentationDoneRight</span></a> <a href="https://mastodon.scot/tags/Altimeter" class="mention hashtag" rel="nofollow noopener" target="_blank">#<span>Altimeter</span></a> <a href="https://mastodon.scot/tags/Barometer" class="mention hashtag" rel="nofollow noopener" target="_blank">#<span>Barometer</span></a> <a href="https://mastodon.scot/tags/Mull" class="mention hashtag" rel="nofollow noopener" target="_blank">#<span>Mull</span></a> <a href="https://mastodon.scot/tags/Antique" class="mention hashtag" rel="nofollow noopener" target="_blank">#<span>Antique</span></a></p>
