Sodium chloride is the chemical name for salt. Sodium is an electrolyte that regulates the amount of water in your body. Sodium also plays a part in nerve impulses and muscle contractions. Sodium chloride is used to treat or prevent sodium loss caused by dehydration, excessive sweating, or other causes.

Baumé degrees (heavy) originally represented the percent by mass of sodium chloride in water at 60 °F (16 °C). Baumé degrees (light) was calibrated with 0 °Bé (light) being the density of 10% NaCl in water by mass and 10 °Bé (light) set to the density of water.

New Continuous Measurement feature to expand your current measuring methods.
Fast Measurements ! Non-homogeneous samples - no problem!

Stir the sample while taking continuous measurements until the readings become stable
Easy Continuous Measurements!

Once the START key is pressed, measurements are taken every second


Ergonomically designed for one-handed operation.Protection class of the PEN is IP65 (Prism head IP67). You can rinse off the sample by running water on the prism. The design allows the user to easily wipe off the sample.
The Automatic Temperature Compensation function of the PEN enables you to take measurement readings regardless of the ambient temperature.Revolutionary new feature ELI*
*External Light Interference (ELI) - Patent Pending.
Convenient Storage case.High temperature sample can be measured.
*Do not dip the instrument directly into a boiling pot to measure; instead, place the liquid in a separate container and measure.
