Chapter 1: Model Specifications and Certifications
1.1 Description
The HY-OPTIMA™ 2700 Series, Explosion Proof In-line Hydrogen Process Analyzer is designed to detect and/or
measure hydrogen using a solid-state, non-consumable sensor that is configured to operate in process gas
streams. The H2scan thin film technology provides a direct hydrogen measurement that is not cross sensitive to
other gases. The hydrogen specific solid-state sensing element is designed for ease of use, interface flexibility
and true process control. The analyzer contains all the circuitry necessary to operate the sensor and present
calibrated hydrogen readings to an analog current output and an RS232 or RS422 digital output. The analyzer is
ideal for hydrogen production and petrochemical applications where real-time measurements can enhance
process plant efficiencies, diagnostics, and maintenance management.
1.2 Models
The HY-OPTIMATM 2700 Series product family includes sensor types that are designed for specific hydrogen
ranges, corrosive gas tolerances and operation when no hydrogen is present. See the guide below for more
details.

an Air, O2, or N2 background.
1.2.1 Model 2710
The HY-OPTIMATM 2710 Process Hydrogen Analyzer has been specifically manufactured to operate in low
hydrogen conditions with increased accuracy.
•Hydrogen Range:
o0.1% to 10% hydrogen by volume at 1.0 atm
•CO and H2S tolerance:
oCO tolerance: 100 ppm
oH2S tolerance: 20 ppm
1.2.2 Model 2720
The HY-OPTIMATM 2720 Process Hydrogen Analyzer has been specifically manufactured to operate in an air or
inert background.

•Operation in background streams in which H2 is not typically present
•Calibration Background Gas: Air or Inert
•Hydrogen Sensitivity Range:
o0.4% to 5% hydrogen by volume at 1.0 atm
o10% to 125% hydrogen lower flammability limit
Note:
Please disregard all warnings and statements to avoid operation in air or oxygen background; these warnings and
statements do not apply to the HY-OPTIMATM 2720 Explosion Proof In-Line Process Hydrogen Analyzers which
have been manufactured for implementation in background gas streams with air.
HY-OPTIMA™ 2720 Explosion Proof In-Line Process Hydrogen Analyzers operating in air do not require the
conditioning procedure.
H2scan recommends the hydrogen gas concentrations for both the Field Verification and Field Calibration gases
to be 1% and 2% hydrogen in a balance of air.
1.2.3 Model 2730
The HY-OPTIMATM 2730 Process Hydrogen Analyzer has been specifically manufactured to operate in full range
(0.5% to 100%) hydrogen conditions with the following enhanced tolerances to CO and H2S in process gas
streams:
•CO tolerance: 100 ppm
•H2S tolerance: 1000 ppm
1.2.4 Model 2740
The HY-OPTIMATM 2740 Process Hydrogen Analyzer has been specifically manufactured to operate in full range
hydrogen conditions with the following enhanced tolerances to CO and H2S in process gas streams:
•CO tolerance: 20% by volume
•H2S tolerance: 3% by volume
