19" Rack Mounted Environmental Dust Monitor
Model 180 

Tech Specs

The Model #180 has been designed for continuous, unattended automatic operation inside a shelter, container, building, etc. measuring continuously the momentary out-door dust mass con­centration of PM₁₀, PM_2.5 and PM₁

This instrument # 180 uses many of the components as the ENVIRONcheck (107 inside 165). However this system is not in outdoor weather protection housing and is not designed for minimum power consumption. Our main objective of this version was to reduce the maintenance to only an annual visit while assuring a very long and unattended operation.

The 180 offers the following features:

• Fully adapted for 19" rack mounted system

• Integrated quick connector to sample pipe attachment

• Integrated spectrometer 1.107

• Automatic dehumidification system

• Simultaneous PM₁₀, PM_2.5 and PM₁ values

• Simultaneous particle size distribution in 15 (or 31 different size ranges

• Instant operation

• Insensitive to vibration

• No radioactive source

• integrated sensors for T +rH + air pressure

• Compact system

• Remote control

A complete 19" wide system, shown at the left, consists of the TSP sampling head on top of the pipe, the attached temperature and humidity sensor, and the dehumidification section, leading down to the upper 2" support rack.

Below the upper rack is the optical dust monitor rack that can be disconnected simply by releasing the lower section via the integrated lift from the upper 2" support rack. This makes the installation and maintenance simple and fast.

The picture below shows as typical installation of the entire system and the appropriate components.

All components, are integrated in the 19" housing. There is no need for any additional pumps, housing, etc. to operate the instrument.  The complete system can be set up, operated and observed from the front side -all items are easily accessible.   In addition, each 180 has:

• An integrated one-wire terminal (for extra sensors)

• An on-line protocol or "Gesytec" call-off mode

• The ability to store data up to one year on the data logger card. It is even possible to use the logger as terminal for other sensors.
