*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. To always get the most accurate measurements, contact
Restek® Customer Service to send in your flow calibrator for service, recertification, and recalibration (cat.# 26462).
** NOTE: Handling, removing, or replacing the battery will void the Alicat warranty.
Alicat M-Series Flow Calibrators
• 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%.**
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.
