Fume Hood Testing

Request a Quote   

Fume hoods are an important piece of equipment in laboratories where chemicals and other materials can cause fumes or exhausts that are harmful to the human body or laboratory environment. The main purpose of a fume hood is to provide an enclosed environment where work can be performed without the risk exposure to those fumes or exhaust. Unlike the exhaust vent you may see in a kitchen over the stove, chemical fume hoods typically require an enclosed environment with a sliding glass enclosure which can be raised or lowered to access the work space (otherwise known as sash).

Depending on the materials being handled and the laboratory environment, some spaces require a variable air volume ventilation system (VAV) which can vary the amount of conditioned air to meet the actual need of the space required. Other spaces may require a constant air volume ventilation system (CAV) which offers a constant quantity of airflow.

Cross offers fume hood testing and fume hood certification with general inspection and verification of fume hood face velocity for various types of fume hoods used for chemical containment. Our fume hood test and calibration procedures satisfy the ANSI/AIHA Z9.5 – 2012 specification for laboratory ventilation and methods of testing performance. An initial inspection includes verification of proper functionality of equipment (sash, electrical outlets, alarm, or airflow monitor) and visual checks for leaks and corrosion, while our face velocity testing offers full reporting of the airflow at recommended sash height.

Did you know… Cross Company is an ESOP (Employee Stock Ownership Plan). Our ESOP started in 1979 and as of 2006, we are 100% employee-owned! Learn more about our ESOP and how that benefits both team members and our customers.
Did you know... the precision measurement group at Cross was founded in 1939 by our current CEO's grandfather, Jim King. That's a whole lot of calibration!
Did you know... A fingerprint weighs about 50 micrograms. We know, we weighed it! The residue left from a finger can actually make a difference in weight results which is why we wear gloves when we calibrate weights. For reference, a sheet of paper is about 4.5 grams, that’s 4.5 million micrograms.
Did you know… Cross Company has grown significantly since our start in 1954. Over the years we've acquired 26 companies! Today, our five groups have expertise in everything from industrial automation to precision measurement, and industry knowledge going all the way back to 1939.
