1.3 MAX-550E Oxygen Sensor
The MAX-550E is a galvanic, partial pressure sensor that is specific to oxygen.
It consists of two electrodes (a cathode and an anode), a FEP membrane and
an electrolyte. Oxygen diffuses through the FEP membrane and immediately
reacts electrochemically at a gold cathode. Concurrently, oxidation occurs
electrochemically at a lead anode, generating an electrical current and
providing a voltage output. Electrodes are immersed in a unique gelled weak
acid electrolyte which is responsible for the sensors long life and motion
insensitive characteristic. Since the sensor is specific to oxygen, the current
generated is proportional to the amount of oxygen present in the sample gas.
When no oxygen is present, there is no electrochemical reaction and therefore,
negligible current is produced. In this sense, the sensor is self-zeroing.
CAUTION: The MAX-550E oxygen sensor is a sealed device containing a mild acid
electrolyte, lead (Pb), and lead acetate. Lead and lead acetate are hazardous waste
constituents and should be disposed of properly, or returned to Maxtec for proper
disposal or recovery.
CAUTION: Dropping or severely jarring the sensor after calibration may shift the
calibration point enough to require recalibration.
CAUTION: The flow diverter for the sensor is for use with flowing gases only.
DO NOT use the diverter when performing static sampling, such as in incubators, oxygen
tents, oxygen hoods, etc.
2.0 SET-UP PROCEDURE
2.1 Battery Installation
All MaxO
2
ME units are powered by four, AA, alkaline batteries (4 x 1.5 Volts)
and are shipped without the batteries installed. The battery compartment is
accessible from the back side of the unit. Batteries should be changed by
qualified service personnel. Use only brand name batteries. Replace with four
AA batteries and insert per orientation marked on the device.
To install the batteries:
1. Release the thumb screw by turning it counter-clockwise until it pops out.
2. Install the four, AA, alkaline batteries (4 x 1.5 Volts) in the unit, observing the
orientation shown on the plastic inside the compartment.
3. Slide the battery compartment cover back onto the case. Press in on the
thumb screw while turning it clockwise until it engages the thread in the
enclosure. Turn until it is lightly tightened. DO NOT over-tighten.
WARNING: Battery replacement by inadequately trained personnel could result in a safety
hazard. The MaxO
2
ME will automatically perform a new calibration any time the batteries are
removed or replaced. Ensure that the sensor is exposed to either 20.9% oxygen (room air) or
100% oxygen when changing the batteries to avoid mis-calibration.
WARNING: Electrical shock or damage to the equipment may occur if an inappropriate
external power supply is used. Maxtec recommends using only the Maxtec approved
external power supply as listed in
