Here's a refined and professional English translation of the provided Chinese text about the RS200 Gas Mass Flow Meter by RETZ:

Brand: RETZ

Innovating in Fluid Control & Measurement Since 2005

Product Overview

The RS200 Gas Mass Flow Meter utilizes thermal measurement principles and advanced flow sensor chips to deliver high-performance, stable, and reliable gas flow monitoring. By measuring resistance changes, it calculates the mass flow rate of gases with precision, stability, and rapid response. Key features include:
- LCD Display: Shows instantaneous/cumulative flow with 90° rotation for flexible installation.
- Wide Compatibility: Measures dry, non-corrosive gases (e.g., air, N?, O?, CO?, Ar; excludes flammable/explosive gases).
- Robust Design: Resistant to extreme temperatures, excellent linearity, and low power consumption.

Applications

Ideal for:
- Research (universities/labs)
- Environmental monitoring
- Fire safety systems
- Smart agriculture
- Pharmaceutical & food industries

Key Features

• Integrated mass flow & temperature measurement
• Multi-range options: 0–50 mL/min to 0–500 L/min
• High repeatability (±1% F.S.)
• Multi-gas support with Modbus-RTU communication
• Adjustable LCD (4-direction display)
• Power: 9–24V DC
