GENERAL DESCRIPTION

GENERAL DESCRIPTION GENERAL DESCRIPTION GENERAL DESCRIPTION GENERAL DESCRIPTION
EC and TDS are instruments specially de-
signed to meet the needs of growers in greenhouses and
hydroponic applications.
The housing has been completely sealed against vapors and
humidity with IP54 rating.
You can simply hang the meter right above the sample to be
tested for continuous measurement.
Both meters come with a probe that compensates for the
temperature variation automatically. The probe is easy to
clean and requires little maintenance.
You can even select your own setpoint and be alerted of an
abnormal situation with a flashing LED alarm.
Measurements are highly accurate and the meters can be
calibrated at one point. In addition, the TDS
uses 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 0.5
is far off the mark in horticulture with high concentrations of
phosphate, nitrogen, etc.
You no longer need to worry about battery changes either:
the unit runs without interruption on 12 VDC power supply.
