Fume Hood Velocity Monitor

The Apex Premier™ utilizes state-of-the-art technology to provide the highest level of performance achievable in a fume hood monitor. The heart of the Apex Premier is the smart sensor module which is responsible for accurate, repeatable and instantaneous measurement of fume hood face velocity. Face velocity measurement is made by an ultra-sensitive micro-bridge mass airflow sensor with a response time of less than 3 milliseconds. The analog signal provided by the micro-bridge is digitized by a high-resolution A/ D converter, then further enhanced and factory calibrated over the operating velocity range by an automated test an calibration system.
