The GPR-7500 analyzer utilizes the low-power electro-chemical sensor technology to provide a cost-effective and easy to maintain online-installation hydrogen sulfide measurement in a small package. The GPR-7100 is a portable H2S analyzer version preferably used for spot checking the process or temporary usage during servicing or commissioning of a permanent installation gas analyzer. These advanced instruments from AII are agency approved for use in flammable gas streams.
