TEK-AIR FLOWMETER - APEX-PREMIER SERIES - HIGH PERFORMANCE FUME HOOD MONITOR

 

The APEX Premier Monitor ensures a safer operating environment for lab personnel with the most versatile fume hood and room transfer velocity monitor available. This monitor is suited for use on all types of fume hoods including Constant Volume, Variable Volume and High Performance Low Flow Hoods. The APEX Premier Monitor can also be used to monitor the velocity of transfer air between critical pressure controlled environments.

Tek-Air Apex Premier

 

.The Apex Premier utilizes state of the art technology to provide the highest level of performance achievable in a velocity monitor. The result is unparalleled reliability and simplistic operation. The Heart of the Apex Premier is the Smart Sensor Module which is responsible for accurate, repeatable and instantaneous measurement of fume hood face or room transfer velocity. The 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 and then further enhanced and factory calibrated over the operating velocity range by an automated test & calibration system. The resulting velocity measurement of the calibrated Smart Sensor Module is an extremely accurate and repeatable signal suitable for use in all fume hood applications.
