产品特点：

Alicat Whisper Flow Calibrators

● 在进入现场之前，快速，准确地验证由真空或压力产生的流速。

● 实时校准气流控制器，无源采样套件，空气罐，采样泵等的理想选择。

● 在广泛的流量范围内测量98种不同气体的绝对压力，质量流量，体积流量和温度。

● 选择基于实验室或方便的电池供电的便携式型号。

* Restek 建议：每年重新校准您的 Alicat 流量校准器以维持终身保修。 长时间未能重新校准设备可能会导致错误增加。 为了始终获得最准确的测量结果，请联系 Restek 客户服务中心，将流量校准器送去进行维修，重新认证和重新校准（目录号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 8 hours (color) or 18 hours (monochrome) of use between charges; rated for 500 cycles before decline to 85%.**
