ISO
17025 NIST Traceable Laminar
Flow Meter/Element
Calibration Services
|
 |
Laminar flow element calibration is a
technical calibration that few
flow calibration facilities can perform to NIST standards with high accuracy. |

ISO
17025 NIST Traceable Turbine Flowmeter
Calibration Services
|
 |
Each time
the rotor spins, the blade interrupts a beam of infrared
light generating a series of pulses that can be measured.
Turbine flowmeter calibration is one of our specialty's |

ISO
17025 NIST Traceable Gas Flowmeter
Calibration Services
|
 |
Graftel maintains five NIST
traceable primary gas flow calibration systems, all of which achieve
uncertainties in the 0.2% of reading range. |
|
ISO
17025 NIST Traceable Thermometer
Calibration Services
|
 |
Graftel has
the capabilities for performing temperature calibrations on almost any
type of temperature measurement or control instrument. |
|
ISO
17025 NIST Traceable Anememeter
Calibration Services
|
 |
Anemometers
measure air volume and air velocity
while Thermo-Anemometers measure both volume and velocity with the added
function of temperature. |
|
ISO
17025 NIST Traceable Rotometer Calibration
Services
|
|
Rotameters are a gauge that consists of a graduated glass tube
containing a free float for measuring the flow of a fluid or gas.
|

ISO
17025 NIST Traceable Humidity Calibration
Services
|
 |
Graftel
maintains two NIST traceable primary humidity calibration systems.
Each is built around a single pressure two temperature
generator. |
|
Pressure Calibration
Services
|
 |
Graftel's
pressure labs are open to perform calibrations to your
pressure measurement equipment. |
|
Gage/Dimensional Calibration
Services
|
|
Graftel works
closely with Fox Valley Metrology as a resource for our Gage
and Dimensional Calibrations.
|
|
Probe Calibration
Services
|
 |
Keeping
your probes for humidity, pressure, and temperature
calibrated is just as important as your standard equipment.
We can make sure that your probes are reading accurately. |

ISO
17025 NIST Traceable Sonic Nozzle Calibration
Services
|
 |
Sonic chokes are converging/diverging nozzles whose operating principles are discussed in every fluid mechanics textbook. They offer the designer a
remarkably simple way to regulate stable gas flow rates. |
|
Force and Measurement
Calibration Services
|
|
Graftel works
closely with Fox Valley Metrology as a resource for our
Force and Measurement Calibrations.

ISO
17025 NIST Traceable Venturi Calibration
Services
|
 |
Venturi
Flowmeters are the simplest and most reliable means of
measuring flow rates. Venturi flowmeters-an 18th
Century solution - are still being selected for measuring
flows in 21st Century process systems because of their
simplicity and reliability. |
|
ISO
17025 NIST Traceable Orifice Plate Calibration
Services
|
 |
The orifice plate is the simplest of the
flow path restrictions used in flow detection, as well as the most economical. Orifice
plate calibration is an important part of maintaining Q/A
