Laboratory & Hood Exhaust
Air Monitor’s airflow measurement systems provide real-time, actionable information required for the safe, code-compliant, and efficient operation of laboratory exhaust and commercial hood exhaust systems. We offer a wide variety of airflow measurement stations, probes, and transmitters for accurate measurement of laboratory exhaust ducts and commercial kitchen ventilation systems.Air Monitor Solutions Can Help
Accurately Measure Dirty, Hazardous Air
One challenge of measuring hood exhaust is chemical compatibility. Our Type 316-SS all-welded measurement probes ensure the sensors are robust and durable, while our individual two-tube design permits high pressure, full volume purge for an effective cleaning for dirty air applications.Maintain Accurate Measurements in Tight Ducts
Air Monitor’s technology permits accurate measurement of the airflow rate in highly turbulent flow locations (with directional yaw and pitch varying up to 30º from the duct's longitudinal axis) without the need for upstream air straightening means.Ensure Safety of Operators in Real Time
Air Monitor’s VOLU-Probe/SS, along with our VELTRON DP series of transmitters, allow laboratory exhaust air flow to be monitored in real-time via transmitter display to ensure the proper exhaust is in place to remove hazardous gases from the area.FAN-E Pitot Airflow Measurement Traverse Station
The FAN-Evaluator airflow measuring station contains multiple total and static pressure precision sensors along with an integral air straightening honeycomb cell. It’s capable of continuously measuring fan discharges or ducted airflow with a certified accuracy of ±2% when tested according to AMCA Standard 610.
VELTRON III Transmitter
The VELTRON III Pressure & Airflow Transmitter is a multi-functional, dual-channel transmitter specifically designed for HVAC airflow measurement applications. The flexible design can be combined with any differential or static pressure measurement probes, stations, piezo rings, or traverse-style fan inlet probes.
Typical applications include supply ducted airflow, return ducted airflow, and room and space pressurization.
VOLU-probe/VS Pitot Airflow Measurement Traverse Station
Air Monitor’s VOLU-probe/VS Airflow Traverse Station utilizes one or more patented Airflow Traverse Probes, factory mounted in a rigid welded galvanized casing, to sense and average separate total and static pressure traverses of an airstream. The station has a certified accuracy of ± 2% when tested in accordance with AMCA Standard 610.
The station is suited for installations in ductwork, fan inlets, etc., operating at temperatures ranging from –20 to 200⁰F. As a primary flow sensing means, the VOLU-probe/VS can be used in harsh exhaust applications including commercial hood systems and laboratory exhaust.
VELTRON DPT 2500-plus Transmitter
The VELTRON DPT 2500-plus is an ultra-low differential pressure and flow smart transmitter designed for demanding HVAC systems.
It is accurate to ± 0.25% of the natural span with both the static pressure level within a space, and that of a reference pressure (corridor, adjacent space, outdoor location, etc.) must be predetermined time intervals while simultaneously holding the transmitter output signal. The automatic zeroing circuit eliminates all output signal drift due to thermal, electronic, or mechanical effects.
LO-flo/SS Stainless Steel Pitot Traverse Probe
The LO-flo Pitot Traverse Station is a combination air equalizer-straightener with a self-averaging Pitot tube traverse station. The LO-flo is fabricated entirely of Type 316 stainless steel with all welded construction and is capable of operation up to 1000ºF.
The LO-flo provides highly accurate measurement of low air volumes of 2 to 2000 CFM for monitoring, indicating, and controlling applications when coupled with ultra-low span electronic differential pressure or flow transmitters such as the Air Monitor VELTRON II.
Applications include pneumatic conveyors, dust collection systems, quench exhaust, and fluidized bed dryers and coaters.
More About Airflow Measurement for Laboratory & Hood Exhaust Systems
Accurate, real-time airflow measurements are critical for ensuring clean air and safe environments for people working around toxic or flammable chemicals in laboratories or in commercial kitchens.
Many regulations, as well as good practice recommendations, exist for maintaining safe and comfortable laboratory and commercial hood exhaust ventilation. Kitchen exhaust hoods remove excess heat and moisture from the environment.
Exhaust ventilation rates (air changes per hour) are stipulated by state and local fire codes as well as national standards, including the NFPA 45 standard on fire protection for laboratories using chemicals, ANSI/AIHA/ASSE Z9.5 for laboratory ventilation systems, and ANSI/ASHRAE 110, for performance testing of laboratory hoods.
Air Monitor systems provide accurate measurement of the airflow rate in highly turbulent flow locations, including laboratory exhaust ducts and fume hoods without the need for upstream air straightening.
