Each
HI98330
is supplied with quick reference guide with instrument quality certificate.
Note
: Save all packing material until you are sure that the instrument works correctly. Any damaged or defective
item must be returned in its original packing material with the supplied accessories.
2. GENERAL DESCRIPTION & INTENDED USE
Ideal for hydroponics and agriculture applications, the
HI98330
GroLine
®
Nutrient Tester accurately measures the
electrical conductivity (EC) in mS/cm and the total dissolved solids (TDS) conversion in parts per million (ppm) of the
nutrients in water.
Suitable for plants that need a higher EC, the tester features an extended range up to 6.0 mS/cm (EC), 3000 ppm
(500 ppm scale), and 4200 ppm (700 ppm scale).
The IP67 waterproof rated and floating casing houses the EC graphite electrodes and temperature sensor, and
is suitable for stirring and testing simultaneously.
