Follow simple, good testing procedures for accurate and dependable results:
Always ensure the sensor is clean before calibrating. If not, clean thoroughly with water (don’t worry, LAQUAtwin meters are completely waterproof!). Place some standard solution on the sensor and press the calibration button. Once the smiley face appears, indicating that calibration is complete, wash off the standard solution with water and dry with a clean, soft tissue.
LAQUAtwin meters only need a tiny amount of sample - so no beaker is necessary. Fill the sensor with the sample and when the smiley face appears, the measurement is complete.
Clean the sensor thoroughly with water, ready for the next test. When the sensor is nearing the end of its usable lifetime, it can be replaced;
1500 measurements or when calibration cannot be completed. Sensors are sold separately and are easily removed and replaced.
Choose the best method according to your sample, your situation and your needs.
LAQUAtwin sampling sheet.
The sampling sheet allows trace volumes to be analysed. For example, you can even measure the pH of human skin by wiping with a sampling sheet soaked in pure water, and placing it on the sensor. Using the HORIBA sampling sheet, volumes down to 0.05 mL can be tested (except for conductivity measurements).
