GPR-7500 (A)IS Online H2S Analyzer
Online ppm hydrogen sulphide analyzer with electrochemical sensor, certified for flammable gas streams.

Combined trace nitrogen and oxygen analysis in one compact instrument.
The LDetek LDSENZ is LDetek's most compact nitrogen and/or oxygen analyzer, pairing its proven Plasma Emission Detector (PED) with the Senz-Tx electrochemical/zirconia sensor series from sister brand Ntron. Combining trace nitrogen and oxygen measurement in the same instrument keeps the footprint small while covering both parameters in a single unit.
A Plasma Emission Detector measures trace nitrogen while a Senz-Tx sensor (zirconia or electrochemical) measures oxygen, sharing one compact enclosure. Results and configuration are accessible via Modbus or the built-in admin web interface.
