The Nutra-Dip Meter has been specially designed for maximum
measurements control. The handy keyboard on the front of the
instrument has all the buttons needed to test various functions. The
use of (ATC) automatic temperature compensation, makes the meter very
accurate by correcting temperature errors.

The display on the front panel displays the pH / mV / °c / EC / CF /
or TDS reading taken by the instrument. The Nutra-Dip uses a mains
charger or batteries as means of power, so the Instruments can be used
static or for field use. The Instruments also has a low battery
warning to alert you the batteries need charging, rechargable
batteries are fitted in the meter ready to go.

The continuous-operating Nutra-Dip measures pH from 0-14, nutrient
EC:from 0.00 -- 19.99EC, TDS:from 10-19990ppm, CF:from 0.0 --
199.9CF and nutrient temperature from 0-100°c, ORP: from -1999-1999
mV. Place it in your reservoir and rely on it for at-a-glance
measurement of these six critical factors. Perfect for many different
industries including Hydroponics, Winerys and Aquatics, Hobbist or
proffesional.
