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. *LAQUAtwin Pen includes plastic carry-case, 14 ml buffer/standard solutions, 2 x CR2032 batteries, dropper.
The only pocket meter that directly measures conductivity in 0.12ml sample. No need for a beaker to calibrate your meter or measure a sample. Just place few drops of the buffer/standard solution or sample onto the sensor. This procedure saves you time and prevents wasting your precious sample. *LAQUAtwin Pen includes plastic carry-case, 14 ml buffer/standard solutions, 2 x CR2032 batteries, dropper.
The only pocket meter that directly measures conductivity in 0.12ml sample and converts it into salinity or salt concentration. No need for a beaker to calibrate the meter or measure a sample. Just place few drops of the buffer/standard solution or sample onto the sensor. This procedure saves you time and prevents wasting your precious sample. *LAQUAtwin Pen includes plastic carry-case, 14 ml buffer/standard solutions, 2 x CR2032 batteries, dropper.
The only pocket meter that directly measures conductivity and total dissolved solids (TDS) in 0.12ml sample. No need for a beaker to calibrate your meter or measure a sample. Just place few drops of the buffer/standard solution or sample onto the sensor.
