1 SS3000e DUAL CHANNEL H2O GAS ANALYZER FOR NATURAL GAS Product Code KEY FEATURES Virtually maintenance free No interference from glycol, methanol or amine contaminants (vapor phase) Accurate, real-time measurements No wet-up or dry-down delays RELIABLE in harsh environments Short term payback; no consumables NIST-traceable calibration Analog and digital Outputs for remote monitoring NEW FEATURES Heated and Unheated Stainless Steel Sample Conditioning Enclosures with NEMA-4X System Rating Optional RS485 and Ethernet Communications AMS100 Analyzer Management Software SpectraSensors SS3000e Dual Channel Gas Analyzer is capable of measuring moisture in this dual channel system which enhances cost savings by incorporating two sensors in one. RAPID RESPONSE TIME The SS3000e analyzer takes four measurements per second with a laser and detector and immediately averages the results. Because there is no contact with the gas, real-time measurements are not hampered by wet-up or dry-down times as with surfaced-based sensors. TRUSTWORTHY MEASUREMENTS Dependable data is an essential element in the quest for improved safety and quality. The SS3000e analyzer delivers precise, reliable measurements using patented Tunable Diode Laser (TDL) technology developed by NASA. The TDL sensor never comes into contact with the sample gas stream. The result is a sensor which does not suffer from contamination or drift due to vapor impurities such as glycol, methanol or amines. The SS3000e dramatically reduces intangible but real costs associated with unreliable gas measurements. By eliminating added processing steps, detecting poor gas quality and the possibility of costly damage to equipment that can result from sensors that produce incorrect data. STATE OF THE ART TECHNOLOGY The analyzer works by shining a laser beam through the sample cell. The laser beam is selected to interact only with the measured compound, creating an absorption signal. The higher the concentration of H2O, the greater absorption of light and the stronger the corresponding absorption signal. Spectrum Software analyzes these absorption peaks to produce very accurate and repeatable measurements. Since the calculation is a direct, fundamental measurement, the amount of H2O present can be measured in realtime. LOW COST OF OWNERSHIP Operating costs are dramatically reduced by eliminating the cost of consumables, extra sensor heads, labor and overhead associated with excessive maintenance.

The sensor measures gas using a patented Tunable Diode Laser Diode (TDL) to determine the concentration of the gas without coming into physical contact with the stream. RAPID RESPONSE TIME The SS2000e analyzer takes four measurements per second with a laser and detector and immediately averages the results. Because there is no contact with the gas, real-time measurements are not hampered by wet-up or dry-down times as with surfaced-based sensors. RELIABLE Trustworthy measurements are vital to natural gas pipeline and processing companies. Independent studies have proven that the SS2000e results are highly correlated with those of chilled mirrors. However, chilled mirrors require skilled experts to operate and the results are highly scattered (large standard deviation). Uncertain measurements can be extremely costly. Additional processing of dehydration costs, upset conditions, shut-ins and inconsistent process results may be caused by sensors that do not perform properly. The SS2000e is the first to offer truly reliable measurement and simple operation. LONG LIFE The TDL sensor does not come into contact with the sample gas stream.

9 SS500e SINGLE CHANNEL H2O GAS ANALYZER FOR NATURAL GAS Product Code KEY FEATURES Virtually maintenance free No interference from glycol, methanol or amine contaminants (vapor phase) Accurate real-time measurements No wet-up or dry-down delays Reliable in harsh environments Short term payback; no consumables NIST-traceable calibration Analog and digital outputs for remote monitoring NEW FEATURES Heated and Unheated Stainless Steel Sample Conditioning Enclosures with NEMA-4X System Rating Optional RS485 and Ethernet Communications AMS100 Analyzer Management Software SpectraSensors SS500e Analyzer is an economical analyzer which utilizes the same state-of-the-art technology as SpectraSensors higher detection analyzers, assuring the user of high reliability and repeatability. RAPID RESPONSE TIME At four measurements per second, the analyzer can measure the fastest changes in the pipeline. Adjustable, real-time results display every seconds. NO CONSUMABLES Because the analyzer s sensor never touches the gas stream it does not get contaminated. The factory set calibration lasts for the life of the analyzer and reconditioning is never required. A read out comparison of the SS500e (left curve) and a slower sensor demonstrates how eliminating long dry-downs can drastically reduce costly shutdown times. In this example, the alarm state is erroneously extended for hours. PAYBACK The SS500e very quickly pays for itself by doing away with expensive consumables, extra sensor heads, labor and overhead associated with excessive maintenance. Costs due to unreliable gas measurements can be reduced by eliminating added processing steps, poor gas quality and the possibility of damage to expensive equipment can result from sensors that produce incorrect data. NO INTERFERENCE As with all SpectraSensors analyzers, the SS500e combines a patented laser with control electronics and smart software. The analyzer s sensor heads are not subjected to corrosives or contaminants in the gas because the sensor is isolated from the sample gas stream. The result is an analyzer which does not suffer from contamination or drift due to vapor impurities such as glycol, methanol, amines, hydrogen sulfide, or mercaptans. STATE OF THE ART TECHNOLOGY The analyzer works by shining a laser beam through the sample cell. The laser beam is selected to interact only with the measured compound, creating an absorption signal. The higher the concentration of H2O the greater absorption of light and the stronger the corresponding absorption signal. Spectrum Software analyzes these absorption peaks to produce very accurate and repeatable measurements. Since the calculation is a direct, fundamental measurement, the amount of H2O present can be measured in realtime.
