Ateq Master Jet
ATEQ MASTER JET – flow master standards (jet, orifice) are used for calibration checking of all types of measuring equipment in accordance with ISO17025 requirements, such as flow testers, flow transducers or rotameters.
The master jets are delivered with a certificate of calibration in a protective box, mounted on a tube fitting.

Note: the values indicated above are given for information only and can vary within ±20%. The true flow value is precisely measured before delivery with an accuracy of ±1.5% of the flow. Special jets can be manufactured within ±5% of its requested value up to 9000 dm3/h.
- Must be used with dry and clean air
- Must not be used under water and must be put in their box after use
- Must be periodically checked by ATEQ’s metrology department
- Checking the zero of the instrument must be done by blanking the instrument test output with a cap
- An extra jet can be provided as option in the same box to allow double calibration checks or a spare master to be used when one is sent to our laboratory for recertification
