NIST refers to National Standards Laboratory which takes itself the responsibility to maintain, develop and retain the custody of the national standards of measurement. It offers methods for making measurements which are consistent with those standards. Any device which has a NIST traceable calibration will have measurements that meet NIST maintained standards and documented uncertainties for each step in the chain. It also has a quality assurance system in place to maintain that measurement uncertainty.

NIST traceable calibration service offers several ways which will help to determine traceability. These ways are:-

 Clearly stated calibration uncertainties

 Traceable records which should be both public and non-proprietary

 Documentation of their calibration methods

 Laboratory accreditation where qualified assessors have looked at laboratory's traceability procedures.

NIST traceable calibration is done with the help of documentation of the measurement process which is used to establish the series of calibrations which link to a specified reference standard. NIST traceable calibrations which are performed in commercial establishments should be documented by the laboratory which is performing the calibration work.

NIST traceable calibration service is provided for: Flowmeters, Gas Monitors, Air Velocity, Humidity, Hydrometers, vibration, weather stations, thermometry and light etc to name a few. There are many service providers who will offer you this calibration service so just get in touch with them for catering to your requirements. They will certify your instruments traceable to NIST standards.

TABmaster Capture Flow Hood is considered to be one of the best tools for checking accurate supply and return of airflow measurements. You can get hoods of different sizes so just choose one which fits your duct. Are you worried about the price? Well, stop worrying because you can purchase it at competitive price which you can easily afford.

TABmaster Capture Flow Hood measures and displays temperature, air flow and humidity. It displays direction of airflow as well as velocity. It has advance storage facilities whereby you can store multiple measurements. This TABmaster has several applications namely:

Air velocity measurement in the duct

HVAC testing, adjusting and balancing

Check filter fouling by measuring differential pressure

Direct readout at supply and return airflow

Air volumetric flow measurements through diffusers and registers
