Continuous Gas Analyzers, extractive
ULTRAMAT 6
General information

■ Overview

Special versions
Special applications
Besides the standard combinations, special applications concerning material in the gas path, material in the sample cells
(e.g. Titan, Hastelloy C22) and measured components are also
available on request
TÜV version/QAL

The ULTRAMAT 6 single-channel or dual-channel gas analyzers
operate according to the NDIR two-beam alternating light principle and measure gases highly selectively whose absorption
bands lie in the infrared wavelength range from 2 to 9 μm, such
as CO, CO2, NO, SO2, NH3, H2O as well as CH4 and other
hydrocarbons.
Single-channel analyzers can simultaneously measure up to 2
gas components, while dual-channel analyzers can simultaneously measure 3 (or 4 on request) gas components.

■ Benefits
• High selectivity with double-layer detector and optical coupler
- Reliable measurements even in complex gas mixtures
• Low detection limits
- Measurements with low concentrations
• Corrosion-resistant materials in gas path (option)
- Measurement possible in highly corrosive sample gases
• Analyzer cells can be cleaned as required on site
- Cost savings due to reuse after contamination
• Electronics and physics: gas-tight isolation, purging is
possible, IP65
- Long service life even in harsh environments
• Heated versions (option)
- Use also in presence of gases condensing at low
temperature
• EEx(p) for zones 1 and 2 (according to ATEX 2G and ATEX 3G)

■ Application
Areas of application
• Measurement for boiler control in incineration plants
• Emission measurements in incineration plants
• Measurement in the automotive industry (test benches)
• Warning equipment
• Process gas concentrations in chemical plants
• Trace measurements in pure gas processes
• Environmental protection
• TLV (Threshold Limit Value) monitoring at the workplace
• Quality monitoring
• Ex versions for analyzing flammable and non-flammable
gases or vapors for use in hazardous areas

TÜV-approved versions are available for measurement of CO,
NO and SO2 according to 13th and 17th BlmSchV and TA Luft.
Smallest TÜV-approved and permitted measuring ranges:
• 1-component analyzer
CO: 0 to 50 mg/m3
NO: 0 to 100 mg/m3
SO2: 0 to 75 mg/m3
• 2-component analyzer (series connection)
CO: 0 to 75 mg/m3
NO: 0 to 200 mg/m3.
Furthermore, the TÜV-approved versions of the ULTRAMAT 6
comply with the requirements of EN 14956 and QAL 1 in accordance with EN 14181. Conformity of the analyzers with
both standards is TÜV-certified.
The analyzer drift can be determined in accordance with
EN 14181 (QAL 3) either manually or with a PC using the
SIPROM GA maintenance and servicing software. In addition,
selected manufacturers of emission evaluation computers
offer the possibility for downloading the drift data via the analyzer’s serial interface and to automatically record and process it in the evaluation computer.
Flow-type reference compartment
• The flow through the reference compartment should be
adapted to the sample gas flow
• The gas supply of the reduced flow-type reference compartment should have an upstream pressure of 3 000 to 5 000 hPa
(abs.). Then a restrictor will automatically adjust the flow to
approximately 8 ml/min

■ Design
19" rack unit
• 19" rack unit with 4 HU for installation
- in hinged frame
- in cabinets with or without telescopic rails
• Front plate for service purposes can be pivoted down (laptop
connection)
• Internal gas paths: hose made of FKM (Viton) or pipe made of
titanium or stainless steel
• Gas connections for sample gas inlet and outlet: pipe diameter 6 mm or 1/4"
• Flow indicator for sample gas on front plate (option)
• Pressure switch in sample gas path for flow monitoring
(option)
Field device
• Two-door enclosure with gas-tight separation of analyzer and
electronics sections from gas path
• Individually purgeable enclosure halves
• Parts in contact with sample gas can be heated up to 65 °C
(option)
• Gas path: hose made of FKM (Viton) or pipe made of titanium
or stainless steel (further materials possible as special applications)
• Gas connections for sample gas inlet and outlet: pipe union
for pipe diameter 6 mm or 1/4"
• Purging gas connections: pipe diameter 10 mm or 3/8"
