COSA Instruments USER MANUAL COSA 707 / OPTIMA 7
Inspect Shipment for Damage
Carefully inspect the entire shipment for damage in the presence of the shipper’s agent, removing
packaging material if necessary. Note any damage to packaging and/or goods on Packing List and
have it signed by the shipper’s agent prior to accepting the shipment. Submit damage claim to
Cosa immediately.
NOTE: Damage claims not received by COSA within 3 days of receipt of shipment will not be accepted.
Important notice!
This high quality electronic analyzer utilizes batteries that discharge even when the
analyzer is not in use. Therefore it is very important to charge the batteries every 4 – 6
weeks, even if the analyzer is not in use. When it is fully charged, the analyzer
should be switched on and allowed to zero itself before being switched off again. (see
chap. 11.8)
Failing to properly charge the batteries will void your warranty!
Save the original box and the packing material for use if the analyzer must be shipped in the future.
This manual is intended solely as a guide to the use of the product.
Cosa shall not be liable for any loss or damage whatsoever arising from content errors or misinterpretation of information’s from this manual or any mis-use resulting from the use of this manual.

COSA Instruments USER MANUAL COSA 707 / OPTIMA 7
2 Introduction
2.1 The COSA 707
The COSA 707 flue gas analyzer is used for:
• Precise flue gas measurement of almost any type of combustion
• Short control of measurements stacks, kilns, furmances and many other sites.
It can also be used (when optionals are activated or external equipment is used) for a number of
measurement tasks, such as:
• Flow velocity measurement of flue gas
• Differential measurement of pressure and temperature
• Combustibles detection with external HC sensor
You will find a list of all optionals for this analyzer on our web page or you can contact COSA or
our local representative.
The COSA 707 Analyzer is available in different versions. This manual will describe all versions
indicating optionals and features not always available on both versions.
2.2 The company
For over 25 years, COSA Instrument has focused on bringing state-of-the-art measurement
solutions to the North American market from leading instrument companies around the globe. The
pioneering approach of supporting its partners with full application engineering and service has
allowed COSA Instrument to successfully introduce new technologies to solve customer
measurement needs. Now combined with the advanced sensor technologies of Xentaur
Corporation, the new entity COSA Xentaur is supplying innovative measurement solutions to
customers worldwide.
2.3 Important general information (EN 50379) and VDI 4206
This analyzer is not designed to be used for continuous measurements.
Before using the analyzer verify the condition of the various parts of the analyzer, such as the
probe, the ambient air conditions, the condensate separator, star filter and the connectors for damage and/or blockages.
When starting up the analyzer it will take between 1 – 3 minutes to set to zero depending on the
condition of the sensors and of ambient.
The minimum zeroing time of the analyzer to achieve correct measurement values can be expected by 1.5 minutes!
Caution: Exposure to acids; aggressive gases such as sulphur; vapours such as thinners, gaso-
line, alcohol and paint, etc. can damage, reduce the life of, or destroy the sensors.
The life of the sensors depends on how they are used, maintained and treated. Typical average life
expectations are: O2 - 2 years; CO - 2 - 3 years; NO - 3 years, NO2 and SO2 approx. 2 – 3 years.
The use of the analyzer for regulatory purposes is subject to special regulations (for example a
periodical examination of the analyzer). Please obtain the appropriate regulations from your local
responsible authority.
2.4 Important information about the users/operation manual
The users/operation manual is an important part of this delivery. It will explain how to use this analyzer properly and sets forth safety and environmentally friendly procedues.
It is the responsibility of all users to read and familiarize themselves with this manual, paying particular attention to the safety instructions.
The most important safety details are listed in chapter 3 (Safety Information). Additional safety details in other chapters are clearly marked with an attention sign.

COSA Instruments USER MANUAL COSA 707
3 Safety Information
The following safety procedures must to be followed at all times. They are a significant and essential part of this manual. Failure to follow safety procedures can result in the loss of your warranty
claims.
3.1 Safety regulations
1. The COSA 707 analyzer may only be used as indicated in this manual.
2. Our analyzers are checked according to the following regulations:
VDE 0411 (EN61010) and DIN VDE 0701 before they leave the factory.
3. Technical products are designed and manufactured according to DIN 31000/ VDE 1000 and
UVV = VBG 4 of the professional guilds for fine mechanics and electrical engineering.
4. The analyzer complies to the essential requirements of the legal regulations of the member
states of the electro-magnetic compatibility (89/336/EWG) and to the low-voltage regulations
(3/23/EWG).
3.2 Specific safety regulations
1. Use only the battery charger supplied with the analyzer for this instrument
2. No part of the analyzer, including the metal probe tube and all other metal parts & accessories
are to be used as electric conductors.
3. The analyzer is not to be used in or under water.
4. The analyzer is not to be placed near or directly exposed to open fire or heat.
5. The specified probe temperature range is not to be exceeded, as the probe, temperature sensory mechanism and sensor could be damaged or destroyed.
6. The analyzer shall void dropping.
7. Caution: Moisture, being pumped out of the condensates trap can be slightly
acidic.
In case of skin contact IMMEDIATELY: clean affected parts of the body.
Avoid getting liquid in eyes.
Please carefully clean all parts that come into contact with the condensates.
8. After measurement, vent the analyzer with ambient air and allow the probe to
cool. A hot probe could cause burns or ignite flammable material.
9. The fumes from certain materials (for. example, cleaners, petrol, spirit, varnish)
may damage the sensors of the analyzer. Do not store or use these or other similar fluids near the analyzer.

4 RETURNED GOODS
Packing regulation of 12.07.1991
If your local waste facility does not except packing materials for disposal, you may return it to our
local sales representative. Packing materials returned to COSA must be returned prepaid.
5 MEASUREMENT PRINCIPAL
The analyzer draws a sample of the flue gases from the duct using a built-in gas pump through the
probe is cleaned and dryed using condensate separator with built-in filter and analyzes the extracted gas with electrochemical sensors.

5.2 Electrochemical measured principle
The oxygen content of the sample gas is measured with a 2 electrode electrochemical
sensor.
Toxic gases like carbon monoxide (CO), nitrogen oxide (NO), nitrogen dioxide (NO2), sulphur dioxide (SO2), and hydrogen sulphide (H2S) are measured with 3 electrode sensors.
The electrochemical sensors are based on gas diffusion technology.
www.cosaxentaur.com
10
COSA Instruments USER MANUAL COSA 707
The advantage of this technology is that the signal generated is direct proportionally and
linear to the volume concentration (% or ppm) of the analysis gas components.
The 3 electrodes are: S (sensing electrode), C (counter electrode) and R (reference electrode).
When the gas being measured contacts the sensing electrode, it reacts on the electrode surface
either through oxidation (for example CO, SO2, NO) or reduction (like NO2, and Cl2).
Example: CO sensor:
Pos.
1 Sample gas
2 Particle filter
3 Sensing Electrode
4 Reference Electrode
5 Counter Electrode
6 Connection pin
7 Electrolyte reservoir
8 Electrolyte
9 Capillary diffusion barrier
CO reacts at the sensing electrode as follows:
CO + H2O -> CO2 + 2H+ + 2e-
and at the counter electrode, oxygen from air will be re-oxidized to water:
½ O2 + 2H+ + 2e- -> H2O
The sensor supplies a constant current signal (µA-range) that is monitored and analyzed. The current intensity is dependant upon the volume concentration of the sample gas, while other parameters like temperature and cross sensitivity are calculated by the analyzer.
