Lab-Based Mass Flow Calibrator, 0-500 SCCM, Monochrome Displ

Quickly and precisely verify flow rates generated by vacuum or pressure before going into the field. These compact, convenient units are ideal for real-time calibration of air flow controllers, passive sampling kits, air canisters, sampling pumps, and more. They measure absolute pressure, mass flow, volumetric flow, and temperature of 30 different gases across a wide range of flows. Choose a lab-based or convenient battery-powered portable model. All units are supplied with NIST-traceable certification. Accurate—NIST-traceable and rated at 0.8% of the reading + 0.2% full-scale repeatability; calibration documents provided with each unit Fast—5 ms response speed with no warm-up required Convenient—no computer connection or software required and all data is visible on one screen Tough—stainless steel construction; unaffected by bumps, humidity, or changes in orientation and supported by an Alicat lifetime warranty.* Downloadable—data can be recorded on a computer via RS-232 connection (unit has no on-board data logging). Long-lasting—portable models with lithium-ion battery offer 5 hours (color) or 18 hours (monochrome) of use between charges; rated for 500 cycles before decline to 85%.** *Restek Recommends: Recalibrate your Alicat flow calibrator once every year to maintain lifetime warranty. Prolonged failure to recalibrate your unit may result in increased error.  ** NOTE: Handling, removing, or replacing the battery will void the Alicat warranty.
