Sper Scientific 850037 Large Display Conductivity Pen - Manual (Page 4)

INTRODUCTION
The Sper Scientific Large Display Salinity
(Model 850036) and Conductivity (Model
850037) Pens provide highly stable and
accurate readings with a large LCD that
simultaneously displays the parameter
being measured and temperature in
°C or °F. The pens are designed for simple
one-hand operation. The case is IP65
waterproof, and will float if accidentally
dropped into the water.
Salinity is displayed not as a percentage
but as parts per thousand (ppt), which
is approximately grams of salt per liter
of solution.
Conductivity is displayed as mhos
per centimeter (M/cm) or siemens
per centimeter (S/cm). Because a mho
(or siemen) is a large unit, microsiemen
or millisiemen typically is used (µS/cm,
mS/cm).
