Core functional advantages

Multi gas and multi range adjustable

Users can change the gas type and full-scale flow rate on site without disassembling the gas and pipeline.

The dedicated configuration software supports one click selection of MR/MG numbers, reducing spare parts inventory and costs.

High precision calibration

Calibration using NIST traceable standard flow system.

Built in massive process gas characteristic database, suitable for toxic and volatile gases.

High speed control

Equipped with a variable PID algorithm, the full range set point response reaches 1 second, which is better than traditional analog models with a response time of 3-5 seconds.

Key questions and answers

Question 1: What are the core advantages of SEC-Z500X compared to traditional simulated MFC?

Answer: The core advantages are full range ≤ 1 second high-speed response (variable PID), on-site multi gas/multi range adjustable without disassembly, ± 1.0% S.P. higher accuracy, support for digital bus communication and eDiagnostic preventive monitoring, and RoHS compliance, significantly reducing spare parts and maintenance costs.

Question 2: What are the accuracy indicators and applicable conditions of SEC-Z500X?

Answer: There are two levels of accuracy - ± 1.0% S.P. when the flow rate * *>25% F.S; When the flow rate is ≤ 25% F.S., it is ± 0.25% F.S; Calibration has NIST traceability * *, compensates for linearity through a fifth degree polynomial, adapts to various process gases in semiconductors, and meets SEMI standards for accuracy.
