A laser optical sensor is used to detect and measure particulate concentrations up to 100 milligrams per cubic meter. The continuous flow optical sensor is combined with purge air to ensure accurate measurements in adverse environments.
The optical sensor, matched electronics and backlit display, are enclosed in a rugged metal enclosure to protect the instrument from normal daily use.
The internal datalogger will store over 5,000 samples. Sample history events can be viewed on the display or downloaded to a computer using Comet software.
The internal battery pack provides over 10 hours of continuous operation. Battery recharge time is approximately 2.5 hours.
The standard unit is supplied with a TSP inlet. Optional sampling inlets are available for PM2.5, PM4 and PM10.
Met One Instruments Inc. is one of the leaders in research, development and manufacture of meteorological instruments, particulate monitors, data loggers and environmental software. One of the oldest instrument manufacturer's in the United States, MOI continues to provide the leading edge in instrumentation, data logging, environmental software and monitoring systems worldwide.
The company began business in 1976 as Met One, Inc. The first of several high quality "Met Set" meteorological monitoring systems and a line of clean room monitoring instruments were introduced. Growth was brisk and the company quickly outgrew the facilities. In 1989 Met One Instruments, Inc. was formed to focus on the growing environmental market and the entire meteorological product line was transferred at that time.
The company has grown through careful planning, dedication to customer service and the ability to design and manufacture quality products. Additional growth has come about with company acquisition and joint venture partnerships
