When benzene, ammonia, and other potentially toxic gases and substances are used in an industrial setting or laboratory, great caution must be used to ensure workers are not accidentally exposed to their dangers. Since these substances can be extremely difficult to detect, it is crucial buildings and other facilities have detection systems in place that can be relied upon to be accurate and working properly 24/7. As new technology has been added to these systems in recent years, many companies now rely on electrochemical gas sensors to help keep employees and facilities safe.


For any electrochemical-type gas sensor to work properly, it must be accurately calibrated based on the work environment in which it is installed. With new electronics being added to these detection systems, they are now able to self-calibrate throughout the day and night. By doing so, they can continually adjust to the work environment based on atmospheric conditions, allowing them to quickly detect even the slightest leaks. In addition, they can be closely monitored by both on-site instrumentation technicians as well as off-site engineers in monitoring centers, giving a facility an added layer of protection.

Multiple Alarms

Since an electrochemical toxic gas detector can be installed in a research laboratory, chemical processing plant, oil refinery, or virtually any other type of manufacturing setting, it will be important to have multiple types of alarms available to alert workers to a potentially dangerous situation. Thus, these detectors are usually equipped with such alarms as sirens, strobes, and flashing lights, all of which can play a vital role should exposure to a toxic gas or substance take place. For example, in a large industrial plant with workers spread out over wide areas, sirens can be very effective alarms. However, should the setting be very noisy due to equipment, strobes and flashing lights can be used to quickly alert workers.

Process Control Systems

As electrochemical toxic gas sensors have become more widely used thanks to their advanced electronics, one of the most useful features for many companies has been their unique process control system. With this system, a sensor can prove to be very cost-effective by gathering information about equipment performance and sending the data in real-time to engineers. Once this is done, engineers and technicians can analyze the data and determine if certain pieces of equipment are working properly. If problems are discovered, technicians can inspect and troubleshoot the equipment, then make repairs or install new equipment as needed.

Confined Space Monitoring

In many industrial buildings, equipment and numerous mazes of pipes and valves are found in confined spaces. Not only can this make it difficult to reliably monitor these areas for gas leaks, but also put workers in these areas at great risk of exposure. Therefore, many companies now invest in portable electrochemical ammonia sensors that are small, clip to belts, and can transmit real-time data to on and off-site personnel. Best of all, they allow for hands-free monitoring while a technician or engineer completes their tasks.
