A moisture analyzer that measures moisture concentration in corrosive gases in ppm units, in addition to measuring moisture in inert gas atmospheres.
★This model has been discontinued. The successor model is the iTMA.★ ● Inline measurement of moisture in corrosive gases is possible ● Measurement range: 0-2500 ppm ● Maximum accuracy ±1% ● Available in rack mount, desktop, and portable options ● Measurable gases: Cl2, HCl, H2S, SF6, H2SO4, SO2, HBr, CO2, Ar, N2, H2, He, D2, O2, C2H2, hydrocarbons, PH3, refrigerants, etc. ■ The TMA series continuous moisture analyzer for corrosive gases utilizes the principle of phosphorus pentoxide (electrolytic) moisture analysis. It is available in desktop, 19” rack mount, and portable types. It also supports Japanese display. In addition to ppm display, simultaneous display of dew point is possible, and all settings such as measurement range, alarm settings, and data logging settings (optional) can be configured from the front of the unit.
