EasyDens conquers Kilimanjaro: How to measure density under extreme conditions

Low atmospheric pressure, low temperatures, and a rough environment: High mountains seem like the perfect place to test a density meter under extreme conditions. So when Robert Amsüss and Robert Breidler, both employees of Anton Paar and also known under the name of Robert2, took off to climb Kilimanjaro, they decided to take the world’s smallest density meter with them and put it to the test.

The idea was born during a Christmas staff party at Anton Paar in early December 2015. Why not climb Mt. Kilimanjaro, the highest mountain in Africa and one of the famous Seven Summits? After a passionate discussion we finally concluded: Let’s do it! However, it was all easier said than done and we soon realized that this adventure would mean a lot of preparation work, physical training, and equipment tests. But the reward for this effort was an exciting time in which both our bodies and the new EasyDens were tested under very extreme conditions.

During this adventure we could prove that:

Density measurement can be done even under extreme conditions.

During our trekking tour we measured with EasyDens several times at various altitudes up to 4620 m above sea level and temperatures as low as only 5 °C. This was, most probably, the first time a precise density measurement was performed at such an altitude.

In other words you could say that with this experiment we proved the functioning of EasyDens for almost all locations on Earth. If somebody out there now wants to go on their own adventure to prove the functionality for the last few missing places they can get an EasyDens in our online shop.

You can do density measurements with a really small and lightweight instrument.

The mobile phone we had with us was more or less the same weight as the EasyDens instrument. The instrument accounted for 192 g in our backpacks (including the battery). The phone weighed 182 g and served as an evaluation unit for the measurements with EasyDens. Calling someone was not possible – you don’t get any mobile network up there – so communication worked only with EasyDens via Bluetooth. But this worked absolutely fine.

We almost forgot that we carried EasyDens with us and additionally our guides motivated us with the Kilimanjaro song several times per day.

It’s easy to operate.

Up on Kilimanjaro it was really cold (5 °C) and additionally we were not used to the extreme altitude. We fought against altitude sickness and had to wear gloves. We were glad that EasyDens could be operated intuitively and with our gloves on. Now, if someone wants to start as the first brewer on Mt. Kilimanjaro we already know they could easily work with this instrument.

It delivers fast results.

We were happy to see that EasyDens worked quickly and precisely. We took our drinking water as a sample and proved it to be clean – a real relief. We also thought about measuring other samples like beer but beer was neither available nor desired due to altitude sickness.

In the end, we were excited to see that we achieved the same repeatability of results as in our hometown of Graz which lies 353 meters above sea level.

These days we are already back home and back at work – but maybe you feel like going on an adventure now? If you do, you can get your own EasyDens to keep you company or request a demo first to see how it works.

Either way: Enjoy your own adventure and don’t forget the Swahili phrase “Hakuna Matata” – No Worries!
