Special Features:

Converts electrical conductivity directly into parts per million (ppm) of total dissolved solids (tds) or ppm sodium chloride (na cl) as selected; dimensions: 3.4 x 4.5 x 4.0 in (86 x 114 x 102 mm); self-contained with built-in cup and sensors; temperature automatically compensated to 25 degrees c (77 degrees f) from 10 to 71 degrees c (50 to 160 degrees f); powered by 9 volt battery; battery life: approx. 2000 tests or 1 year shelf life; ranges: 0-5000 ppm tds or 0-5000 ppm sodium chloride

Properties:

An electrically operated instrument which indicates the sea salt content of fresh water systems and is usually calibrated in grains per gallon. The value may be expressed by means of a pointer and calibrated dial or a digital readout display.
