Temperature detector protecting tubes are detachable.
Note: These detectors cannot be used with highly corrosive liquids and solutions likely to stick
to sensors. If it is desired to be applied to solutions containing slurry or sludge, consult with
YOKOGAWA. For measuring NaOH solutions, use sensors with a nickel vibrator.
