IH1200 Flow Restrictor – Silonite Coated

Flow Restrictors for IH1200 Personal Monitoring System

Product Description

The IH1200 Personal Monitors utilize classical vacuum sampling into MiniCansTM and Bottle-VacsTM to perform STEL or TWA monitoring for up to 12 hours. Like HDS Personal Monitors, sampling using the IH1200 eliminates the concentration and matrix effects associated with adsorbent-based sampling techniques. The IH1200 is universal, recovering all analytes in a single sampling event with no need to choose different media. Large flow rate adjustments are made by changing inlet restriction (see table below), while fine adjustments (2–3x) are made using a built in flow adjust feature. Enough sample is collected to allow multiple analyses in the laboratory, with detection limits down to low PPB if needed. The IH1200 meets the requirements of OSHA Method PV2120 for determination of workplace contaminants using MiniCanTM samplers. The sampling procedure is easy: Connect an evacuated MC450QT MiniCanTM or 500mL Bottle-VacTM  and sampling starts. Monitor the fill rate on the built-in gauge to document a constant fill rate during the sampling event; disconnect the canister to stop sampling.
