| '''Question:''' Is it possible to us the oxygraph with a chamber temperature of 0 °C?
| |
| | |
| Our system is specified down to 4 °C at 25 deg room temperature and and down to 2 °C at "lower ambient temperature", see
| |
| [http://www.oroboros.at/index.php?id=o2k-specifications| specifications].
| |
| Lower ambient temperature does not necessary mean a "cool room". For the 2 deg, an acclimatised room usually will be enough.
| |
| While we can only guarantee the working of the instrument within these limits, it is possible to go to 0°C and has been done. In general, this may require a "cool room". To this purpose the main unit itself can be exposed to temperatures down to just above 0°C (all the electronic components are rated at least down to 0°C but obviously 0°C room temperature has to be avoided due to condensation concerns). Also of course for very low room temperatures above 0 deg humidity has to be controlled somehow.
| |
| We did a quick test today and could reach 0°C chamber temperature quite easily at a room temperature of about 14 °C. To keep this temperature stable the cooling power of the Peltier element was already working at 95% of maximum, so some kind of cool room will probable be necessary
