Sierra releases the Cal=Trak XL flow calibrator

Sierra Instruments has released the Cal=Trak XL Primary Standard Gas Flow Calibrator for high flows up to 500 slpm.

Ideal for calibration of gas-measuring instruments, including mass flow meters and controllers, Cal=Trak XL offers accuracy of +/- 0.25 per cent of reading.

The dimensionally based primary accuracy of the Cal=Trak XL is backed by a rigorous uncertainty analysis.

It is a primary standard piston prover that operates with the press of a button.

At 24.6"(W) x 33"(H) x 12"(D), Cal=Trak XL fits on any laboratory bench, replacing large bell provers with one integrated package.

It can be used in the manufacture, inspection, validation and recalibration of mass flow controllers, flow meters and many other varieties of flow equipment with flow rates too high for common primary standard devices.

In either manual or automatic operation, the Sierra Cal=Trak XL measures, displays and outputs the flow of gas, either in mass or volumetric units.

The menu-driven configuration of the Cal=Trak XL allows end-users to customise the calibrator to fit their changing needs.

The single integrated piston chamber of the Cal=Trak XL can measure flows from 5 to 500 slpm, over a 100:1 range.

Used in conjunction with other Cal=Trak models, a metrology lab can be established that is capable of calibrating gas flow meters from five sccm to 500 slpm for a combined turndown ratio of 10,000:1.

Cal=Trak XL comes with Sierra's Cal=Soft application software.

This package downloads the digital output of the calibrator to a PC, storing calibration data in a spreadsheet and allowing calibration certificates to be generated automatically.

Technicians can use Cal=Trak XL without expensive calibration control.

The Cal=Trak XL is suited for applications in fields where higher flow rates of gas are becoming common: metrology, semiconductor, analytical, medical, pharmaceutical and quality control among others.

The Cal=Trak XL provides primary NIST traceability, is manufactured under strict ISO 17025 certification and is CE approved.
