Precision Calibration of Your Gas Flow Meter With Cal=Trak
If you're looking for accurate calibration for your in line gas flow meter or lab instruments, the portable and low-maintenance Cal=Trak SL-500, SL-800 and XL models will give you the precision results you need. Whether measuring natural gas or an inert gas such as argon, you just can't go wrong with a gas flow meter from Sierra.
Sierra, one of world's most preferred gas flow meter manufacturers, presents the much anticipated successors to its well-known but discontinued Cal=Bench line of primary standard piston provers from the 1990's. The high-quality relays in the Cal=Trak SL-500 offers an excellent accuracy of ±0.35% of reading while the Cal=Trak SL-800 offers the best accuracy of any commercially available standard: ±0.15% of reading! And if you manage high gas flow, the XL model also provides powerful ±0.25% accuracy up to 500 slpm.
