When using 2 point calibration with Air and pure Oxygen at constant temperature
User programmable with the My Nitroxbuddy app
Any gas with O2 content in the 0.5% to 100% range. For better accuracy we recommend to calibrate device using 2 point calibration method and using two gasses with O2 content close to gas being analyzed
Nitroxbuddy can operate with any of the following sensors: Analytical Industries Inc. PSR-11-39-MD, Maxtec MAX-305 and MAX-305F, Teledyne R-22S or DiveNav Nitroxbuddy O2 sensor. The estimated lifetime in air of the DiveNav Nitroxbuddy O2 sensor is 12 months
Nitroxbuddy uses a CR2032 3v battery that can be replaced by the user. Estimated lifetime is based on performing 10 measurements per month
