The only pocket meter that directly measures pH in 0.1ml sample (or 0.05ml sample with sampling sheet B). Unique sensor allows measurement of viscous liquids, solids, and even powder samples. No need for a beaker to calibrate your meter or measure a sample. Just place few drops of the standard or sample onto the flat sensor. This procedure saves you time and prevents wasting your precious sample.

Follow simple, good testing procedures for accurate and dependable results:
- Calibrate correctly.
- Avoid mixing samples and standards.
- Always keep the sensor clean
Always ensure the sensor is clean before calibrating.
If not, clean thoroughly with water (LAQUAtwin meters are waterproof to IP67)
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.
2. Test
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.
3. Clean
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; * you don’t need to replace the meter.
* Sensors will need to be replaced after approx.
1500 measurements or when calibration cannot be completed. Sensors are sold separately and are easily removed and replaced.
