The Combo HI 991404 meter is designed for continuous, high accuracy pH, EC/TDS and
temperature 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, backlit
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 stability indicator and hold features 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 (ß) 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 volt dc transformer and are easy to
install and use.

These state-of-the-art meters have been engineered with a host of features suited to the
aggressive environments commonly found in agricultural applications; housings and
cable connections have been sealed against vapor and humidity. With a 12 volt DC
power supply included with the meter, low battery failures are never an issue. Locate the
meter right above the sample to be monitored or take it with you for spot checking. Select
HI 983301N for TDS measurements with the common 0.7 TDS conversion factor (4-4-2)
or HI 983301N/5 which uses a 0.5 conversion factor.
Both the TDS and EC meters come with a probe specifically made for horticulture and
hydroponics applications. The probe compensates for temperature variations
automatically, is easy to clean and is very stable, needing little maintenance.

Designed for continuous monitoring of pH, TDS and temperature, the HI 981504 is
simple to install and can be placed above the sample to be tested. pH, TDS and
temperature measurements are simultaneously displayed on three backlit LCDs which
can be easily viewed at a distance - even in low light. This means no more switching
between parameters.
The HI 1286 gel-filled pH electrode is provided with a waterproof sheath to protect the
BNC connector. The unique design of the electrode provides longer life in aggressive
solutions. The HI 7634 TDS probe is easy to clean and requires little maintenance.
Measurements are accurate and the meter can be calibrated at one or two points for pH
and at a single point for TDS. Temperature range is factory calibrated

The HI 98129 Combo waterproof tester offer high accuracy pH, EC/TDS and temperature
measurements in a single tester! No more switching between meters for your routine
measurements. The waterproof Combo (it even floats) has a large easy-to-read, dual-
level LCD and automatic shut-off. pH and EC/TDS readings are automatically
compensated for the effects of temperature (ATC). This technologically advanced tester
has a replaceable pH electrode cartridge with an extendable cloth junction as well as an
EC/TDS graphite electrode that resists contamination by salts and other substances.
This gives these meters a greatly extended life. Your tester no longer needs to be thrown
away when the pH sensor is exhausted.
The EC/TDS conversion factor is user selectable as is the temperature compensation
coefficient (ß). Fast, efficient, accurate and portable, the Combo pH, EC/TDS and
temperature tester brings you all the features you've asked for and more!

The original DiST (Dissolved Solids Tester) was first introduced in 1986 by HANNA®.
Since then, Conductivity and Total Dissolved Solids measurements have never been
easier. DiST's ease-of-use, in combination with its affordability, made it the standard in
EC and TDS measurement. HANNA® continues the tradition of innovation with the DiST
5. For this series, we have included all the features you have asked for and more! The
DiST 5 6 includes features such as a replaceable graphite electrode, adjustable TDS
ratio, temperature in °C or °F, automatic temperature compensation (ATC) with
adjustable ß, battery level indicator, stability indicator, automatic shut-off and automatic
calibrating all in a floating, waterproof casing. This 3-in-1 tester is unmatched in
EC/TDS/Temperature measurements!

HI 9813-6N is a versatile, water resistant multiparameter portable meter specifically
designed for agricultural applications such as hydroponics, greenhouses, farming and
nurseries. It features an extra large LCD that clearly displays the parameter being
measured as well as calibration instructions. Calibration is fast and easy with knobs
located on the front panel of the instrument. HI 9813-6N is designed for simplicity of use
in taking pH, mS/cm, ppm and temperature in the °C scale measurements. HI 9813-6
includes all the features of the HI 9813-5 while incorporating our exclusive CAL
CHECK™ feature. CAL CHECK™ allows the user to easily check the probe calibration
status at any time. Comes with the HI 1285 series pH/EC/TDS/temperature probe. This
probe features a fiber junction and gel electrolyte making it ideal for fertilizer solutions.
