Features
Space-saving amplifier built-in type
EX-F1 amplifier built-in sensor saves space as there is no need to install a separate amplifier.
Easily mountable and adjustable
|
Just attach it on a pipe with the tying bands. The position can be easily changed with the release lever even after mounting, so that there is no need to cut the tying bands.
|
|
Low price
EX-F1 is very cost-effective.
Easy to check operation Indicator
|
The operation can be checked at a glance from different directions.
|
|
Operation mode switch
Either Light-ON or Dark-ON can be selected by a switch. This is useful to check the operation during installation because it forces the output to be turned ON or OFF even without the liquid being inside the pipe.
