The Defender series of primary flow meters offer light, ultra-compact Dry-Cal technology for calibrating sampling pumps. Easy to use, they measure volumetric flow and standardised flow and correct for temperature and pressure.
We have a range of flow meters to calibrate your personal sampling pump in the field. It is recommended that all pumps are calibrated pre and post sample.
A low flow adaptor enables a high flow sampling pump to operate at the lower flow rates required by some standardised methods (2-200ml per min).
These are grab sampling bags for sampling gases and vapours. Made from chemically inert Tedlar, they are re-usable if purged with nitrogen and have either stainless steel or polypropylene fittings.
