Take control of problem odors and corrosion with H₂S monitoring
Eliminating hydrogen sulfide odors and mitigating corrosion is a costly challenge for wastewater treatment plants. The durably designed GS1440 and GS2440EX hydrogen sulfide sensor from Hach are the only solutions that can give wastewater treatment plant managers full visibility into where and when the problem originates. These sensors help you to tackle this issue at the source -- reducing unnecessary spending on chemical dosing.
Reliable, real-time H2S data and trends can easily be accessed via wireless or hard-wired connections, so that you will gain actionable insights into H2S levels, protect valuable assets from corrosion, and avoid public nuisance from odor.
*All sensors should be calibrated on-site with the calibration kit upon installation, and at regular intervals thereafter (every 1-6 months depending on the application). Calibration gas and kit can be purchased via https://certgas.com/
** The Cable Guard accessory should be installed with any sensors that are intended for intermittent or continuous submersion in water. Please see the accessories page for all accessory and cable options.
Hydrogen sulfide sensors from Hach provide precise, liquid-phase H₂S measurements in real time, offering visibility into odor hotspots and potential corrosion zones. When coupled with the simplicity of the SC4500 controller, Hach’s H₂S sensors make it easier than ever to make data-driven decisions and optimize chemical usage -- saving your facility time, effort, and operational costs.
The turbulence that causes the H₂S to go into the air can be a distraction from where the problem actually begins -- helping you to quickly resolve odor concerns protects residents’ well-being and builds trust with the local community.
Unlike gas-only sensors that fail when exposed to moisture, the GS1440 and GS2400EX are engineered for reliability in harsh conditions in water or air. Their durable construction ensures consistent and accurate performance even in the most demanding applications, so you can focus on your process without interruptions or uncertainties.
This instrument's corrosion-resistant design can be inserted in pipes or installed in a flow cell, making ultra-tight spaces easy for continuous H₂S monitoring. Cleaning is as simple as wiping the sensor head before each calibration, and calibration only takes five minutes.
