Harsh Enviro Tech

Product Code:

HET 345

Product Description: The Fine particle sampler HET 345 is known for its durable and better-quality cabinet design. Offered with a softer handle, lockable instrument to keep secure samples.  Ambient air enters the HET 345 system through an Omni-directional inlet designed to provide a clean aero-dynamic cut point for particles greater than 10 micros. Particles in the air stream finer than 10 microns proceed to a second impactor that has an aero-dynamic cut point at 2.5 microns. The air sample and fine particulates exiting from the PM2.5 impactor is passed through a 47 mm dia. polytetrafluoroethylene (PTFE) Teflon filter membrane that retains the PM2.5. This is a manual method of sampling PM2.5micron particulate matter based on impactor designs standardized by USEPA.
Special features:
  • Significantly reduced noise as compared to most instruments in the market.
  • Lockable doors and gaseous attachment keep secure samples.
  • Improved cabinet design which is more durable and sturdy with SS hardware.
  • Additional advantage with this sampler is very low variation in flow rate in 190-230V input power supply range.
