Made in Japan
Manufacturer: Tokyo Keiso
Model: HM1000
HM1000 is the thermal mass-flow controller which is the combination of a mass flowmeter for gas with control valve. A mass-flow rate can be measured and the flow rate of various gases is controlled with high accuracy without being influenced by change of temperature and/or pressure. There are two types available: a)low-cost type and b)general-purpose type.
