Ammonia Gas Analyzer: GPro 500

Ammonia Gas Analyzer: GPro 500

Tunable Diode Laser for NH₃ Measurement

The GPro 500 ammonia (NH3) gas analyzer is a unique TDL spectrometer designed for direct measurement of ammonia in stack measurement and ammonia slip applications. It uses a folded-path laser beam design for low maintenance, accurate measurement.

Top Performance in Ammonia Measurement
An NH3 analyzer for challenging applications, the GPro 500 provides reliable measurement in ammonia slip and stack measurement applications.

Low Maintenance and Operating Costs
This ammonia gas analyzer is designed to operate in situ without a maintenance-prone conditioning system, reducing the total cost of ownership.

Easy Installation
The GPro 500 is an alignment-free TDL gas analyzer, meaning that the typical challenges of TDL installation and alignment are significantly reduced.
