1. Project Background

Keywords: Retention Pond, Hydrogen Sulfide, Ammonia, Temperature

Monitor ammonia and hydrogen sulfide levels, as well as temperature, within the retention pond.

Ambient temperature, high humidity (gas drawn from the retention pond contains some moisture), normal pressure, dust-free environment,

H₂S: 0–25 ppm

NH₃: 0-25 ppm

Temperature: -40°C to +120°C (actual gas temperature is ambient)

Testing Purpose: To verify the effectiveness of the client's own equipment in purifying hydrogen sulfide and ammonia. Results must be displayed to two decimal places.

2. Solution

Use a simple pre-treatment device to filter out moisture from the gas before measuring its concentration.

Pump-drawn system: gas from the retention pond is drawn through a pipeline for testing.

The product is installed outdoors with a stainless steel housing and an IP67 protection rating.
