HAND HELD MONITORS - Indoor Air Quality Systems
APAQ Group distributes the full range of Handheld Particle Counters by Met One Instruments in Singapore, Indonesia and other countries in South-East Asia.
Particle counters are a range of products designed specifically to be highly portable, easy to operate and cost-effective. They enable quick indications, normally within a minute's sampling time, for trace aerosol concentrations suspended in air in either particle count, or mass concentration to ensure the cleanliness, safety and hygiene of the production facilities or workplace. Common functions may also include printable result charts, real-time viewing of data on PC or audible alarms to notify the user when a certain limit is exceeded.

ISO 21501-4 CALIBRATION CERTIFICATE (optional)
ISO 21501-4 Optional Calibration (P/N SVC0109) now available on select Met One Instruments Inc. Particle Counters
ISO 21501 is a standard describing instruments and calibration requirements for determining particle size distribution using light scatter methods. With the increasing trend for real-time air particle monitoring in clean rooms and controlled environments, Met One Instruments, Inc. is prepared to meet the demands of our customers who require this critical calibration.
Released in May 2007, ISO 21501-4 is a particle counter calibration standard that replaced older standards such as ASTM and JIS. These previous standards outlined calibration of particle counters but lacked repeatability between units. The Pharmaceutical industry immediately adopted and embraced the new ISO 21501 standard. Other industries are slowly following their lead. While this standard is primarily a clean room standard it will likely influence other industries relying on particle counting size and count accuracy.
