Alicat Whisper Flow Calibrator, Portable, 0-500 SCCM, Monochrome Display, Battery Powered
Overview
- Quickly and precisely verify flow rates generated by vacuum or pressure before going into the field.
- Ideal for real-time calibration of airflow controllers, passive sampling kits, air canisters, sampling pumps, and more.
- Measure absolute pressure, mass flow, volumetric flow, and temperature of 98 different gases across a wide range of flows.
- Choose a lab-based or convenient battery-powered portable model.
*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).
- 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—<1 ms sensor response time.
- 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 18 hours (monochrome) of use between charges; rated for 500 cycles before decline to 85%.**
