Teledyne Max-5 - Combustion efficiency analyzer - Manual (Page 12)

.32
For a mixture of 70% Hydrogen and 30% Carbon Monoxide:
0.7(2.0) + 0.3(2.0) = 3.5%
.86 .32
CAUTION
In most cases, the concentration of any particular compound that the sensor is exposed to should
not exceed the LEL of that compound or sensor damage could occur.
The concentration of combustibles should never exceed that which will react completely with the
available oxygen present in the sample (stoichiometric burning), otherwise “coking” (the
deposition of carbon from incomplete combustion) will occur at the sensor, and drift and a loss
of sensitivity will result.
Note: For compounds not listed in Table 1, consult Teledyne Brown Engineering/Analytical
Instruments.
Because of the electrochemical properties of the B-3 oxygen cell, the MAX 5 is designed for
spot checking, not continuous on-line application. The maximum continuous sampling period
should not exceed 30 minutes, followed by a 30-minute purge with atmospheric air.
INSTALLATION AND START-UP PROCEDURES
Upon receipt, of the MAX 5, inspect the entire unit for damage. If damage is found, notify the
shipper. Check unit, and included accessories, for broken or loose parts. DO NOT CONNECT
THE INSTRUMENT UNTIL ALL INSTRUCTIONS HAVE BEEN READ! If damage is
not found, check for the following parts:
* Probe
* Power Cord
* Sensor - F-1R - blue label, B-3 - orange label. (The Combustible sensor is factory installed).
* Instruction Manual
* Calibration Kit - Optional, however, required for calibration purposes.
* Printer (optional)
* Printer interface (with printer option)
* RS-232 Module (with printer option)
PRECAUTIONS
1.
Do not press on the sensing surface (membrane) of the Micro-Fuel Cell sensor.
Puncturing or other damage will require replacement of the sensor.
2.
The F-1R and Micro-Fuel cell sensors contain a caustic mixture, which is harmful if
touched, inhaled, or swallowed. In case of eye contact, immediately flush eyes with
