Low Volume Air Sampler
Version 1.6

Met One Instruments is now part of the Acoem Group. The Met One
range of gas analyzers was originally developed by Acoem under
the brand name Ecotech MicroVol 1100.
For the purposes of expediting the availability of Met One gas
analyzers to Met One customers around the world; Met One
Instruments have chosen to use the original Ecotech MicroVol
1100 operating manual.
Although the name of the Met One instrument is different, the
analyzer itself has remained unchanged and meets the strictest
quality and performance requirements expected of Met One
equipment. All the information presented in this manual is
current, including analyzer specifications and operating
principles.
Met One will update this manual to reflect the new branding
convention in due course.
