Open-Path NH3 analyzer

Required Minimum Specifications:

• The analyzer must be a commercially available, single-unit system capable of measuring NH3 concentration, with a lower detection limit of 8 ppm-m and upper detection of 5,000 ppm-m with a 1% reading accuracy and resolution of 0.2%.

• Path length of coverage range from 5-500 m.

• Remote diagnostics and data transmission via wireless communications.

• Dual thermoelectric cooler controller enables a laser temperature stability to +/-0.001C.

• Practically no temperature related drift from -40 to 50C.

• Dynamic Real-time Pressure and Temperature Compensation via Internal Pressure &

Temperature sensors

• Store up to 20 years of data
