1.0 INTRODUCTION
1.1 General
Bacharach’s line of CO
2
analyzers are easy to use, but it is essential that
this instruction manual be read, understood, and followed by all operators
and maintenance personnel prior to using or servicing the analyzer.
CO
2
analyzer models 2825, 2830 and 2835 are all compact and light-
weight instruments that principally measure and display CO
2
concentra-
tions, with each of the various models offering the ability to also measure
barometric pressure, O
2
, temperature, and relative humidity.

Each reading is displayed separately on a backlit LCD, with an operator
being able to quickly scroll through all the readings by pressing the f
3
button. A peak-gas-reading mode enables an operator to view the highest
gas reading that was taken since the analyzer was switched ON.
Each analyzer can store all measured readings in memory, which can
later be downloaded to a personal computer via its integral IrDA commu-
nications link and the optional BACH-COM software.
