About Technologies Key Points

Technology is a core strength at Enviro Test Construct. We’ve integrated it into select products and systems, and our technical team, comprising engineers, technical support, and sales staff, has become proficient in its utilization.

Here's a detailed breakdown of some key technologies

Sensor Technology

These sensors utilize infrared light to measure the concentration of specific gases like carbon monoxide (CO), carbon dioxide (CO2), and volatile organic compounds (VOCs). They’re widely used for their accuracy, reliability, and low maintenance requirements.

PIDs detect a broad range of VOCs by measuring the ionization caused by ultraviolet light. They’re more sensitive to VOCs than NDIR sensors but offer less specificity.

These sensors measure gas concentrations based on the electrochemical reaction of the gas with an electrode. They’re commonly used to detect gases like CO, nitrogen dioxide (NO2), and sulfur dioxide (SO2).

These sensors measure the concentration of particulate matter (PM) in the air. Various technologies are employed, including light scattering, beta attenuation, and piezoelectric sensors.

Emerging Technologies

Satellite and drone-based technology can provide aerial monitoring of air quality over large areas. This is particularly useful for monitoring large construction sites or areas with limited accessibility.

These sensors are equipped with advanced processing capabilities and can analyze and interpret data on-site, providing more detailed information and real-time insights.

AI algorithms can be used to analyze air quality data, identify trends, and predict future air quality conditions. This can help construction companies proactively manage air quality risks.

Sampling and Analysis

This involves continuous monitoring of air quality parameters using sensor technology. The data is displayed in real-time, allowing for immediate response to any fluctuations in air quality.

This involves collecting air samples at specific intervals for analysis in a laboratory. This method provides detailed information about the composition of air pollutants but doesn’t offer real-time data.

Data Management and Communication

Wireless communication systems like Wi-Fi, cellular networks, or satellite communication can be used to transmit data from remote monitoring locations to a central hub for real-time access and analysis.
