Pierce your sample
All Unisense microsensors can be equipped with a steel needle, except the N2O microsensor. This modification is useful if you are measuring through a rubber septum, or in coarse or hard samples where a hole has been drilled prior to microsensor measurements.
The needle sensors are strong on the longitudinal axis, but due to the larger sensor tip diameter, Unisense does not recommend to use the sensors for microprofiling in sediment or biofilm.
The microsensor tip is inserted into a steel needle giving the sensor maximal strength on the longitudinal axis.
