The Industrial Air Quality Monitor Model T9M241270, is a versatile transducer designed to continuously monitor for the presence of airborne particulates. The T9M241270 is calibrated for OSHA and EPA regulations.
T9M241270 is suitable for monitoring particulate emissions from cyclones, precipitators, baghouses, or any dust control devices. It is also ideal for monitoring air quality in underground transportation systems, ventilation systems, indoor workplaces, or any other application where immediate data on smoke, dust, fumes, or mists is needed. The T9M241270 warns you of problems before they become trouble.
The T9M241270 easily mounts on walls inside air ducts or at strategic locations in dust collectors, baghouses, or any dust control device. Units can be configured in a single or multipoint system.
Applications
Monitor PM-10 emissions for EPA title 1 compliance of the Clean Air Act.
Continuous monitoring of particulate discharge from cyclones, baghouses or dust control devices.
Multipoint monitoring of in-plant dust generating processes.
Activates air cleaners/ ventilation systems.
Continuous monitoring of in-line filter integrity.
Indoor air quality monitoring.
Air quality monitoring.
Air quality in underground transportation systems.
Aerosol exposure studies.
Dry solids process control & monitoring.
Can be used for all particulate air emissions monitoring applications.
We will work with you to design a custom package to meet your specific application.
The T9M241270 utilizes an optical layout consisting of an infrared emitter and silicon detector. As particles enter the sensing area an analog output, current or voltage, provides a signal which is proportional to the particle concentration. The signal can be sent to a recorder or central processing panel.
