HI9811-5 and HI9812-5 are pH/EC/
TDS waterproof meters designed for
simplicity in taking pH, μS/cm, ppm (mg/L)
and temperature measurements. both
the HI9811-5 and HI9812-5 are ideal for
hydroponics, greenhouses, farming and
ground water applications .
Due to the built-in temperature sensor,
conductivity readings are automatically
compensated for temperature changes.
The temperature coe#cient is $xed at
No probe changes are required when
switching your measured parameter
between pH, conductivity and TDS. These
multiparameter meters reduce the number
of instruments required for daily water
