Our medical grade calibration gas is compatible with the SmartTank Certain test modes require gas bottles. The specific mixture to use is defined by the gas monitor OEMs. The SmartTank will only accept gas bottles from Witting Innovation. These bottles meet or exceed all OEM quality standards and are provided with an RFID tag which allows the SmartTank to collect details about the calibration gas for the report.  This also allows the SmartTank to check that the correct gas is being used for the DUT.
