Alicat M 系列流量校準(zhǔn)器

Accurate—NIST-traceable and rated at ±0.75% of reading or ±0.1% of full-scale (whichever is greater); calibration documents provided with each unit.

Fast—

Sensitive—built for ambient conditions; ultra-low pressure drop of 0.07 psid.

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 or micro USB (unit has no onboard data logging).

Long-lasting—portable models with lithium-ion battery offer 8 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. 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.
