Hastings Instruments 200H Mass Flowmeter

Description:

The Hastings 200H Thermal Mass Flowmeter is used to accurately measure the mass flow rate of clean gases without requiring pressure or temperature compensation, providing precise and repeatable flow measurement for laboratory, industrial, and process control applications. Commonly installed in semiconductor manufacturing equipment, analytical instrumentation, gas blending systems, environmental monitoring equipment, leak testing systems, research laboratories, and OEM process gas delivery systems. Maintenance technicians, calibration specialists, and system integrators use this mass flowmeter for repair, retrofit, replacement, and preventive maintenance of gas flow measurement and control systems. 

Applications:

The Hastings 200H Thermal Mass Flowmeter is commonly used in semiconductor processing, gas chromatography, environmental monitoring systems, pharmaceutical manufacturing, medical research, thin film deposition, chemical processing, leak detection equipment, gas mixing systems, calibration laboratories, and industrial process control applications requiring accurate low-flow gas measurement.
