Product description

Parameters

Features

1. High Accuracy and Fast Respond

The accuracy of the CS300 MFC has been improved to ±0.8% of S.P., and the most advanced models have a less than 0.5 sec response time.

2. Low Zero Drift and Temperature Coefficient

The invention of new sensor technology enables the CS230 MFC to maintain stability and withstand temperature fluctuations. Without an auto-zero amplifier, the expected zero drift is less than 0.6%F.S./year, and the temperature coefficient is less than 0.02%F.S./℃(zero)，0.05%F.S./ ℃ (span).

3.Metal-Sealed Models and High Purity Feature

The special metal surface process is applied in CS300. 316 stainless steel VV is used and rough ness could be less than 5 RA which is required by the semi standards.

4. Compatible Interfaces

The CS300 MFC is compatible with the following interfaces, which may be selected by the customer:±8V-±16V double-end power supply and +14V-+28V single-end power supply; digital or analog signal input and output; SEMI standard mechanical dimensions; and RS-485 or DeviceNetTM communications module.

5. Miscellaneous Functions

Powerful customer software comes standard with each model, while additional functions such as multi-gas，multi-range，auto-zero, alarms, soft start, and delay are available as customer selections.

6. CS300 MFCs support 1.125", 1.5" W, C IGS.
