Electrochemical Sensors
At MDC Systems, Inc., we understand that gas detection is only as reliable as the technology behind it. Electrochemical sensors play an important role in monitoring toxic gases and oxygen levels in commercial and industrial environments where safety, compliance, and operational continuity matter every day. When properly selected, installed, calibrated, and maintained, an electrochemical sensor can provide accurate, dependable readings that help protect people, equipment, and facilities from hazardous conditions.
We provide gas life safety system solutions designed around the specific needs of each application. Our team works with facilities that require dependable gas monitoring, detection, and control systems, and we use our experience to help clients choose the right sensing technology for their environment. Whether your facility needs oxygen monitoring, carbon monoxide detection, toxic gas detection, or integration with a larger gas life safety system, we can help build a practical solution that supports safety and performance.
What Are Electrochemical Sensors?
Electrochemical sensors are gas detection devices that measure the concentration of a target gas through a chemical reaction. When gas enters the sensor, it reacts with an electrode inside the sensing cell. This reaction produces an electrical signal that corresponds to the amount of gas present. The gas detector then translates that signal into a readable concentration, alarm condition, or control response.
Because this technology is sensitive and selective, electrochemical sensors are commonly used for toxic gas and oxygen detection. They are often selected for applications where low-level gas detection is required and where accurate readings are essential to workplace safety.
Common gases monitored with electrochemical sensor technology include:
- Carbon monoxide
- Hydrogen sulfide
- Oxygen
- Chlorine
- Nitrogen dioxide
- Sulfur dioxide
- Ammonia
- Hydrogen
- Ozone
- Other toxic or reactive gases, depending on the application
Each gas presents different risks, so we evaluate the environment, gas type, operating conditions, and monitoring goals before recommending a sensor or system design.
Why Electrochemical Sensors Matter
Many hazardous gases cannot be seen, smelled, or detected by people until the risk has already become serious. In some cases, exposure can occur quickly. In other cases, a small leak can build slowly in a room, enclosure, laboratory, mechanical area, storage space, or process environment. Electrochemical sensors help identify dangerous conditions before they escalate.
We use electrochemical sensor technology in gas detection systems because it supports:
- Early warning for toxic gas exposure
- Continuous monitoring in high-risk areas
- Oxygen deficiency and enrichment detection
- Worker protection in occupied or controlled spaces
- Alarm activation when gas reaches unsafe levels
- Integration with ventilation, shutdown, or notification systems
- Compliance support for facilities with gas safety requirements
Our goal is to help clients monitor critical areas with dependable equipment and practical system designs that are built for real operating conditions.
Applications for Electrochemical Sensor Systems
Electrochemical sensors are used across a wide range of commercial, industrial, laboratory, and specialty environments. At MDC Systems, Inc., we design and support gas detection systems for facilities where hazardous gases may be stored, used, produced, or released during normal operations.
These sensors may be appropriate for:
- Semiconductor and electronics facilities
- Laboratories and research facilities
- Manufacturing plants
- Battery charging areas
- Wastewater treatment operations
- Chemical storage rooms
- Mechanical rooms
- Medical and healthcare facilities
- Universities and institutional buildings
- Industrial gas distribution areas
- Confined or enclosed spaces
- Facilities using toxic, corrosive, or asphyxiating gases
No two facilities are exactly alike. That is why we take a customized approach to every project. We consider the gases present, room layout, air movement, process equipment, occupancy, alarm requirements, and local code considerations when designing or supporting a system.
Our Approach to Electrochemical Sensor Solutions
We do more than provide a device. We help clients build complete gas detection solutions that align with their safety goals and facility requirements. Our approach begins with understanding the application. From there, we help determine where sensors should be located, how alarms should function, what controls may be needed, and how the system should be maintained over time.
Our electrochemical sensor services may include:
- Application review and gas hazard evaluation
- Sensor selection and placement guidance
- Gas detection system design
- Installation support
- Startup and commissioning
- Controller and alarm integration
- Calibration and functional testing
- Preventive maintenance
- Sensor replacement recommendations
- Troubleshooting and system upgrades
We focus on reliability, usability, and long-term cost of ownership. A gas detection system should not only perform on the day it is installed. It should continue to provide dependable protection through proper calibration, testing, and maintenance.
Calibration and Maintenance
Electrochemical sensors require regular calibration and maintenance to remain accurate. Over time, sensor performance can be affected by age, gas exposure, environmental conditions, humidity, temperature, contaminants, and normal wear. Routine calibration confirms that the sensor responds correctly to a known concentration of gas.
We provide calibration and maintenance services to help ensure that gas detection systems continue operating as intended. During service, we can inspect equipment, verify readings, test alarm functions, evaluate sensor response, and identify components that may need attention. This proactive approach helps reduce false alarms, missed alarms, downtime, and unexpected system issues.
A properly maintained electrochemical sensor can provide meaningful protection, but a neglected sensor can create a false sense of security. We help our clients avoid that risk by supporting consistent testing and maintenance practices.

Frequently Asked Questions
What is an electrochemical sensor used for?
An electrochemical sensor is used to detect and measure specific gases, especially toxic gases and oxygen. It is commonly used in gas detection systems to provide early warning when gas levels become unsafe.
How does an electrochemical sensor work?
The sensor produces an electrical signal when the target gas reacts with an internal electrode. The gas detector uses that signal to estimate gas concentration and trigger alarms or control responses when needed.
What gases can electrochemical sensors detect?
Electrochemical sensors can detect gases such as carbon monoxide, hydrogen sulfide, oxygen, chlorine, nitrogen dioxide, sulfur dioxide, ammonia, hydrogen, and other gases, depending on the sensor type.
Do electrochemical sensors need calibration?
Yes. Electrochemical sensors should be calibrated regularly to confirm accuracy and proper response. Calibration helps ensure that the gas detector provides reliable readings when hazardous gas is present.
How long does an electrochemical sensor last?
Sensor life varies based on the gas being detected, exposure levels, operating environment, manufacturer specifications, and maintenance history. We can help evaluate sensor condition and recommend replacement when needed.
Where should electrochemical sensors be installed?
Sensor placement depends on the gas type, room layout, ventilation, equipment location, and potential leak sources. We evaluate each application so sensors are placed where they can provide effective monitoring.
Are electrochemical sensors right for every gas detection application?
No. Electrochemical sensors are well-suited for many toxic gas and oxygen monitoring applications, but other technologies may be better for combustible gases, VOCs, or certain specialty environments. We help determine the best technology for each project.
