PRELIMINARY EXAMINATION
EC and TDS
are instruments specially de-
signed to meet the needs of growers in greenhouses hydroponic
applications. They are equipped with a large Liquid Crystal
Display for an easy reading also from distance.
You can simply hang the meter right above the sample to
be tested for continuous measurement and the unit will run
without interruption on 12 VDC power supply.
The housing has been completely sealed against vapors and
humidity.
The meters are supplied with a probe that automatically
compensates for the temperature variation. The probe is
easy to clean and requires little maintenance.
Measurements are highly accurate and the meters can be
calibrated at one point.

In addition, the two TDS
use a specially
devised formula which perfectly reflects the needs of growers.
In fact, the common method of measuring Total Dissolved
Solids by multiplying the conductivity by a converting value
is far off the mark in horticulture with high concentrations of
phosphate, nitrogen, etc.
In the HI 983301N model the TDS factor is 0.7 while in the
HI 983301N/5 is 0.5.
