This specimen allows the temperature and the density of the product to be taken directly on the tank, without transfer and without influence of the meteorological conditions.
The thermometer is permanently fixed in the specimen and the densimeter corresponding to the product to be controlled is introduced before The specimen fills up when going down into the tank.
Once out, we drain the first third using the opening tab, allowing to let the densimeter float freely.
The reading is done by transparence.
To empty the test tube, just turn it over of the tank, without removing the stopper, the specimen empties through the air passage hole on the plug, so it avoids the breakage of the densimeter by not handling it.
