Made In Japan
Manufacturer: Nippon Flow Cell
Model: NFH
Thermal Flow Cell Mass Flow Meter
By combining an orifice with a thermal sensor, the device accurately measures gas mass flow without needing corrections for pressure or temperature changes. Its humidity- and water-resistant sensor design ensures long-lasting durability.
