General Information
General Information
Overview
The CH88 In-Situ Combustion O2 Analyzer System is Rosemount Analytical’s latest combustion flue gas oxygen analyzer
consisting of 1056 Combustion Electronics and CH88 Flue Gas O2 Probe. This product is intended for measuring the flue
gases resulting from any combustion process. It utilizes the same heated sensing technology as the O2 sensors found in most
automobiles. Contact Rosemount Analytical’s technical support group at 800-433-6076 for any applications other than
measuring combustion flue (exhaust) gases.
This product utilizes an “in situ” sensor, i.e. the sensor is placed at the end of a probe, and the probe extends directly into the
flue gas duct or stack at a given length. The sensor is like a thermocouple, generating it’s own millivolt signal based on the
difference between a reference gas (ambient or instrument air – always 20.95% O ), and the flue gases being measured.
2
System Configuration
CH88 Flue Gas O2 Probe with 1056 Combustion Electronics
There are no electronics inside the probe head, so the raw sensor signals for the heater thermocouple and zirconium oxide O sensor
are sent to a remote 1056 Combustion electronics. The 1056 Combustion electronics will also directly apply power to the probe heater
in order to maintain the correct sensor temperature. This arrangement calls for a 9- conductor cable to carry this power and the
sensor signals. Maximum length for this cable is 500 feet. This probe will also operate on previous Westinghouse/Rosemount
electronics (World Class and Oxymitter), as well as many competitive electronics.
CH88 Flue Gas O2 Probe does not communicate via HART or FOUNDATION Fieldbus communications.

Calibration
September 2017
CMB_MAN_ABR_CH88
Calibration
The CH88 In-Situ Combustion O2 Analyzer System can be calibrated in the installed condition without removing the
instrument from the process duct and also while the combustion process is on-line. A stainless steel tube runs the length
of the probe, and delivers the calibration gasses into the cell area. Factory calibration will usually be satisfactory for initial
start-up and operation, but most accurate measurement is gained by executing a calibration under normal operating
conditions.
Recommended calibration gases are 0.4% O and 8% O , with the balance of nitrogen in the gas bottles, but other values
can be used as long as the electronics are configured identically. Instrument air or pure nitrogen are not recommended as
calibration gas values. A two-stage pressure regulator should be used to establish a pressure of 20 PSI, from the bottles,
and the flowmeter should be set to 5 SCFH flow rate.
2 2
Manual/Semi-automatic Calibration
The CH88 Flue Gas O2 Probe with the standard housing can be calibrated in a semi-automatic fashion, with a technician
following prompts via the display of the 1056 Combustion Electronics. The technician will need to manually switch the
gases based upon these prompts. Recommended calibration gases are 0.4% O2 and 8% O2, balance nitrogen. A
two-stage pressure regulator should always be used, set to 20 PSI. The calibration gas flowmeter should be set for 5
SCFH, with the cal gas fitting removed from the probe. A diffuser/filter that is plugged over time may cause the flowmeter to
deliver less flow to the sensing cell, but the flow rate should never be readjusted until a new diffuser is installed.
Readjusting the flowmeter back up to the 5 SCFH level could pressurize the cell during calibration, and cause the O2
reading to shift downwards.
The electronics will determine if the calibration was successful, and calculate new calibration values. New calibration
values are automatically loaded into the electronics after a successful calibration. Record the calibration data on the log
provided (cell slope, constant, and impedance, as well as the speed of response data).

CAUTION
Make sure that the calibration gas cap is replaced tightly after calibration is complete. Many combustion processes operate at a
slight negative pressure (draft pressure), and can draw ambient air down the cal gas lines and into the sensing cell, causing a
false elevated O reading. This same phenomenon is possible if the calibration gas hoses are permitted to become degraded or
