GPR-7500 and GPR-7100
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 an permanent installation gas analyzer. These advanced instruments from AII are agency approved for use in flammable gas streams.
