For the horizontally installed probe whose insertion length is 2.5 m or more, use the Probe Protector. Be sure to specify

ZO21R-L-200-. Specify the flange suffix code either -C or -K.

The thickness of the flange depends on its dimensions.

Inconel probe bolts and U shape pipe are used. Use this option for high temperature use (ranging from 600 to 700°C).

Specify either /CV or /SV option code.

Specify either /SCT or /PT option code.

No need to specify the option codes, /CV and /SV, since the check valves are provided with the Automatic Calibration Unit.

Automatic calibration cannot be used when natural convection is selected as reference gas.

Sun shield hood is still effective even if scratched. Hood is necessary for outdoor installation out of sun shield roof.

Recommended if sample gas contains corrosive gas like chlorine.

Piping for reference gas must be installed to supply reference gas constantly at a specified flow rate.

*10 Output signal limits: 3.8 to 20.5 mA. Specify either /C2 or /C3 option code.
