The MD300 Oxygen analyzer is the same analyser that we use on all our diving panels. These models offer exceptional performance and reliability that users will come to appreciate. Using state of-the-art design concepts and manufacturing techniques the microprocessor-based AD300 Oxygen Analyzer and MD300 Oxygen Monitor with Alarms offer unique features that set these instruments apart from the competition.
With a microprocessor on board functions such as calibration are a snap. Just turn the unit on press the CAL key and the computer does the rest. Pressing the lock key protects the calibration setting. The MD300 with alarms easily allows the user to save settings. The two models also featuring Teledyne&rsquos own R-17D oxygen sensor with enhanced temperature tracking and superior long-term stability and accuracy.
