2. GENERAL DESCRIPTION
HI9813-51
and
HI9813-61
are portable, water resistant meters,
designed for measuring pH, EC / TDS, and temperature when paired with
their respective probes, i.e.
HI9813-51
with
HI1285-51
and
HI9813-61
with
HI1285-61
.
The meters are easy to use, with dedicated keys for measurement modes
that are clearly displayed on the LCD, and knobs for 1-point calibration
of pH and EC. On-screen tutorial messages guide the user through
calibration and measurement.
Main Features
• 3-in-1 combination probe with pH, EC /T DS, and temperature sensors
• CAL Check™ (
HI9813-61
only)
• Best for hydroponics, greenhouses, farming, and ground water app.
Probe features
The polypropylene (PP) body houses three sensors:
pre-amplified pH electrode:
Cloth junction, Polymer-gel electrolyte,
Low temperature (LT) glass-sensing bulb
amperometric EC/TDS sensor:
Two stainless-steel prongs for
determination of conductivity and total dissolved solids
NTC Thermistor (built-in):
Ensures that readings are compensated for
temperature variations
