Prepare the measuring cell for the next sample. 5.4.1 Fill the measuring cell and measure the density Because the measuring cell always contains residue from the previous sample or the cleaning solution, it is important that you remove the residue using the new sample. This is only possible if the residue is soluble in the new sample. Handheld Density Meter 11 To achieve good results, make sure that the measuring cell contains only the sample you want to measure and that there are no bubbles in the measuring cell. You can use the sample pump or syringes to fill, drain and rinse the measuring cell. The sample pump is used for samples with a viscosity up to 100 mPa*s. Syringes are typically used if the viscosity of the samples is above 100 mPa*s. You can find more information on working with the syringe in the Reference Manual. u www.mt.com/library See also Example: Density determination using the sample pump } Page 12 5.4.2 Prepare the measuring cell for the next sample At the end of this phase, the residue in the measuring cell must be soluble in the next sample. The solubility of the sample defines if you can drain the measuring cell or if you need to rinse it. Drain If the next sample dissolves the sample you just measured, you can drain the cell. Rinse If the next sample does not dissolve the sample you just measured, you have to rinse the measuring cell with a cleaning solution. The cleaning solution must dissolve the sample that you just measured and the next sample. When you rinse the measuring cell, the cleaning solution removes the residue from the original sample. See also Clean the measuring cell } Page 15 5.5 Example: Density determination using the sample pump The following chapters show you how to configure and perform a density determination of deionized water at room temperature (23 °C or 73.4 °F). Summary of the configuration • • • Guided density determination Filling and draining with the sample pump Evaluation if result lies within specified limits You can find more information about the configuration of a method in the Reference Manual. u www.mt.com/library 5.5.1 Configure the method § The density unit is set to [g/cm3]. § Confirmation of results in Settings is activated. § The home screen is open. 1 Move the navigation joystick to the left. ð The Methods window opens. 2 Press the New key. ð The Method settings window opens. 12 Handheld Density Meter 3 Navigate to Method ID and enter a name with up to 25 characters. 4 Press the OK key. ð The method is listed in the Methods window. 5 Change the parameter settings to the values shown in the following table. Parameter Setting Explanation Workflow Guided The density meter prompts users to fill and drain the measuring cell. Sample ID entry Variable The density meter prompts users to enter the sample ID before the density is measured. Fill cycle The density meter prompts users to fill and drain the measuring cell twice and then fill the measuring cell for the measurement. Fill speed High The pump fills the measuring cell with 80 % of the maximum pump speed. Measurement reliability Medium The result is saved as soon as the measured temperature value stays within 0.4 °C (0.72 °F) for 10 s. Calculation > Category Density A density is calculated. Calculation > Calculation The density is not compensated to a certain temperature. Calculation > Result limits Yes The density meter evaluates if the result is within a defined range. Lower limit 0.9972 g/cm3 Defines the lower limit of the range. Upper limit 0.9977 g/cm3 Defines the upper limit of the range. Clean Drain Users are prompted to drain the measuring cell.

Any other maintenance tasks need to be performed by a service technician that has been qualified by METTLER TOLEDO. 14 Handheld Density Meter If you experience problems with your density meter, contact your authorized METTLER TOLEDO dealer or service representative. METTLER TOLEDO recommends that a preventive maintenance and calibration certification is done at least once a year through your authorized METTLER TOLEDO dealer or service representative. u www.mt.com/contact 6.1 Maintenance schedule If the standard operating procedures of your company require other maintenance intervals, use the intervals listed in the standard operating procedures. Frequency Task Daily Clean the measuring cell at the end of the work [Clean the measuring day. cell } Page 15] See Perform a test with deionized water. [Check the measurement accuracy } Page 16] 6.2 Clean the density meter NOTICE Danger of damage to the density meter due to inappropriate cleaning methods! Inappropriate cleaning agents can damage the housing or other parts of the density meter. If liquids enter the housing they can damage the density meter. 1 Make sure the cleaning agent is compatible with the material of the part you want to clean. 2 Make sure that no liquid enters the interior of the density meter. If you have questions about the compatibility of cleaning agents, contact your authorized METTLER TOLEDO dealer or service representative. u www.mt.com/contact 6.2.1 Clean the housing METTLER TOLEDO recommends the following cleaning agents: • • Water Water with a mild detergent Procedure § The density meter is shut down. − Wipe the housing with a cloth moistened with the cleaning agent. 6.2.2 Clean the measuring cell Because the measuring cell always contains residue from the last sample, there is a risk that the measuring cell can be damaged by the sample. To prevent such damages, METTLER TOLEDO recommends that you clean the measuring cell at the end of each sample series. To clean the measuring cell, you need to rinse the measuring cell with a cleaning solution. The cleaning solution must have the following properties. Does not chemically interact with the material of the measuring cell. Dissolves the sample that was just measured. • Evaporates without leaving incrustations. METTLER TOLEDO recommends the following cleaning agents: • • Sample Cleaning solution Water Water based Deionized water Handheld Density Meter 15 Sample Cleaning solution Acids, concentrated Water (flush the measuring cell with plenty of water to remove the heat from the reaction of water and acid) Alkaline, concentrated 0.3…0.5 % deconex solution Samples with fats or oily compoents 0.3…0.5 % deconex solution Petrochemical samples Edible oils and fats Toluene, xylene or petrol ether mixtures 6.2.2.1 Clean using the sample pump § The density meter is set up to work with the sample pump. § The cleaning solution is defined and available. § The piston is in the lowermost position. 1 Immerse the filling tube in the cleaning solution (1). 2 Move the navigation joystick upwards and let go. ð The sample pump starts and stops when the piston is in the uppermost position. 3 Lift the filling tube out of the cleaning solution and hold it over the waste beaker (2). 4 Move the navigation joystick downwards and let go. ð The sample pump starts and stops when the piston is in the lowermost position. 5 Clean the end of the filling tube with a clean tissue. 6 Repeat the steps until all residue from the sample is removed. 7 Move the navigation joystick upwards and let go. ð The sample pump fills the measuring cell with air. 8 Move the navigation joystick downwards and let go. ð Most of the cleaning solution is removed from the measuring cell. 9 Clean the end of the filling tube with a clean tissue. 6.3 Check the measurement accuracy To check the measurement accuracy of the density meter, you need to configure and perform a test.
