 HI
981404N • HI 981405N - pH/EC
and pH/TDS Indicators for Agriculture
HI 981404N and HI 981405N are
ideal for agricultural, horticultural
and hydroponics applications where
pH and TDS or pH and EC levels
need to be continuously monitored
for optimal plant growth. HI 981404N
and HI 981405N continuously monitor
and display the pH and TDS or
pH and EC values of a solution
on an easy to read set of dual
LCD's. The HI 1286 gel filled
pH electrode is replaceable and
the BNC connector is protected
behind a waterproof sheath. The
unique design of the electrode
guarantees greater clogging resistance
in fertilizer solutions with high
concentrations of phosphate, nitrate,
etc. TDS measurements are performed
using the 4-4-2 conversion factor
of 0.7 so you do not need to convert
the readings. Both models are
equipped with a grounding bar
to ensure more accurate pH measurements
and longer electrode life. The
HI 981404N and HI 981405N are
compact and easy to install and
use. This makes them ideal for
all continuous monitoring applications.
HI 981404N is supplied complete with HI 1286 pH electrode, HI 7634 TDS probe, HI 1283 grounding bar, pH and TDS calibration solutions (20 mL each), screwdriver, 12 Vdc adapter and instructions.
HI 981405N is supplied complete with HI 1286 pH electrode, HI 7632 EC probe, HI 1283 grounding bar, pH and EC calibration solutions (20 mL each), screwdriver, 12 Vdc adapter and instructions.

 HI
991404 • HI 991405 - pH/EC/TDS/Temperature
Monitors with Back-lit Display
The Combo HI 991404 and HI 991405
series meters from Hanna are designed
for continuous, high measurements.
These microprocessor indicators
continuously monitor the three most
important nutrient parameters in
hydroponics, greenhouses and horticultural
applications with a single instrument.
These indicators feature a large,
dual-level, back-lit LCD to give
you instantaneous readings of pH,
EC or TDS and temperature, even
from a distance.
At startup, these indicators perform
a self-check to assure proper working
condition. HI 991404 and HI 991405
also have a stability indicator
and hold feature to prompt the user
when to take the reading and freezes
the display for easy and accurate
recording. Calibration and temperature
compensation is automatic, while
the EC/TDS conversion factor and
temperature coefficient (?) are
user adjustable for application-specific
measurements. These instruments
are supplied with an advanced, non-clogging
double junction pH electrode and
a rugged conductivity probe that
will withstand even the most aggressive
environments. The instruments are
powered by a 12 Vdc transformer
and are easy to install and use,
making them ideal for all continuous
monitoring applications.
HI 991404 is supplied complete with HI 1293D pH electrode, fixed HI 7630 probe, pH and EC calibration solutions, 12 Vdc power adapter and instructions.
HI 991405 is supplied complete with HI 1293D pH electrode, fixed HI 7630 probe, pH and EC calibration solutions, 12 Vdc power adapter and instructions.
