Portable 3 in 1 pH, TDS and Conductivity System
- Model
HI9812
HI9812 allows the user to professionally measure pH, EC (conductivity)
and TDS with a single portable meter. pH is measured over the full scale, the
EC range has been expended to 4.00 mS/cm and the TDS range or 0.00 to 1990 ppm
is ideal for water conditioning, aquariums, agriculture and fish farming. The
HI1285 probe is engineered to resist contamination and therefore last longer.
Particularly suited to harsh conditions, the replaceable probe incorporates
a pH electrode with a cloth junction and gel polymer electrolyte for long life
and greater stability of reading. HI9812 is powered by 9V battery and features
BEPS (Battery Error Prevention System) to avoid errors due to low battery power.
Three Meters in one
The portable HI9812 is a convenient, accurate and cost-effective tool to measure
pH, EC and TDS.
EC & TDS Temperature Compensated
The HI1285 probe utilizes a temperature sensor to provide readings that are
automatically compensated for temperature.
Economical, Convenient & Accurate
About the same price as two testers with the advantages of a professional meter.
pH, TDS and EC in 1 rugged sensor!
The specilized HI1285 sensor was designed to measure pH, EC & TDS without
changing instruments or probes. This rugged sensor has been designed for fast
response, longer life and the greatest accuracy. HI1285 3-in-1 pH/Conductivity/TDS
probe is warranty for six
months.
