Indicator paper for the determination of water in butter according to DIN 10 311. The storage life of butter is closely linked to the size of the water and buttermilk particles it contains. For this reason it is important to check the water distribution during the manufacturing process and before storing larger quantities. The WATOR indicator paper allows an exact means for controlling the water distribution. Evaluation charts according to the 5-point evaluation system are available on request. On contact with water, WATOR develops dark-blue spots, the size and number of which is correlated to the distribution of the water in the butter. Instruction Sheet (pdf)

WATESMO is a test paper for the detection of water in the liquid as well as the vapor phase, in the liquid phase in aliphatic and aromatic hydrocarbons (gasoline, oil), in isopropanol and higher alcohols, in waxes, for determination of absorptive moisture in salts, in solid fats as well as aqueous emulsions of ointment bases. Depending on the type of sample, a water content of more than 10 - 15% can be indicated with WATESMO paper. In the vapor phase (indirect determination) the test strip is dipped into absolutely anhydrous Isopropanol and, while still moist, is placed into the medium to be tested, such as a current of air. The isopropanol acts as a solvent aid between the water vapor and WATESMO. After evaporation of the alcohol in the driest possible atmosphere, a blue color will appear, the intensity of which depends on the amount of water vapour present. WATESMO changes color from light blue to deep blue. Do not touch the test paper, except with absolutely dry fingers or forceps. Instruction Sheet (pdf)

Test sticks for the determination of water in petrol and fuel oil tanks tanks or for the determination of the thickness of oil layers in oil separators. In the course of time frequently water accumulates in petrol and fuel oil storage tanks forming a layer underneath the fuel. We recommend a special test stick to determine the depth of this water layer. To ensure the proper function of oil separators, accumulated oil layers must be removed frequently. The thickness of such oil layers can also be determined with AQUATEC paper.
The test stick consists of a polyester film 0.2 mm thick and 10 x 200 mm coated on one side with a dark blue, water-soluble layer, which is insoluble in petrol and fuel oil. In order to determine the presence of water beneath the petrol or fuel oil, the test stick is fixed to a flat stainless steel sheet (approx. 25 cm long, 3 cm wide and 3 mm thick) so that the lower ends coincide. The test stick is then lowered into the tank by means of a thin cord or wire until it reaches the bottom. Instruction Sheet (pdf)
