Access Door: For access to the Micro-Fuel Cell and transmit- ter controls, the front door swings open when the slotted latch in the middle right side of the door is turned counter-clockwise. The replaceable Micro Fuel Cell is housed in a nylon cell block posi- tioned for easy access.
OT-2 Electronics & Display: The OT-2 meter display is a LCD device that produces 3.5 decimal, 7-segment numbers that are legible in daylight. It produces a continuous readout of oxygen cencentration. Accessing the transmitter electronics requires unfastening the screws of the transparent front cover of the OT-2 and lifting the cover off.
Flowmeter: Monitors the flow of gas past the sensor. Readout is 0.1-1 standard cubic feet per hour (scfh).
H2S Scrubber: The H2S scrubber prevents H2S gas from affect- ing the oxygen sensor.
