GPR-7100 Portable H2S Analyzer
Portable ppm hydrogen sulphide analyzer with electrochemical sensor, intrinsically safe for field use.
Key Features
- Electrochemical H2S sensor (OSV-72-7HH)
- Ranges 0–20, 0–50 and 0–100 ppmV
- Accuracy < 2 % of selected range
- Lower detection limit 0.1 ppmV
- LCD display, 0–1 V DC output
- Intrinsically safe: ATEX/IECEx Ex ia IIC T4 Ga, cMETus Class I Div 1 Groups A–D

Overview
The GPR-7100 portable hydrogen sulphide analyzer is designed for field H2S measurement. Using low-power electrochemical sensor technology, it delivers cost-effective, minimal-maintenance H2S measurement in a compact design, and is certified for use in flammable gas streams.
Working Principle
An OSV-72-7HH electrochemical sensor measures H2S in the sample (1:1 air:sample ratio, application dependent). The reading is shown on the LCD and output as a 0–1 V DC signal; the analyzer runs from an internal battery charged by a 100–240 V AC charger.
