Product Description

HI-991301 High Range EC, TDS, pH and °C Meter

Complete with probe

2 year manufacturer warranty

The HI-991301 is a light weight, portable pH, conductivity and temperature meter for

portable applications requiring both a pH and conductivity measurement. Applications include

measurements for greenhouses irrigation, hydroponics and groundwater monitoring from

agriculture nutrient pollution.

The HI-991301 meter features two operation button and is simple to use. All operations and

settings, including calibration buffers and temperature scale selections, are made through

these two buttons. It has a waterproof and compact casing rated for IP67 conditions and a

large tri-line display. The meter has automatic pH calibration at one or two points and a

single conductivity calibration. Other user selectable features include different TDS

factors from 0.45 to 1.00, and a range of temperature coefficients from 0.0 to 2.4% for

better conductivity or TDS solution temperature compensation. The meter is supplied with a

multi-parameter probe specifically designed for this meter.

Main features:

Simultaneous, pH, EC/TDS and temperature measurements on a large three line LCD
display

Selectable temperature unit

pH electrode condition display

About the HI-12883 probe

The HI-12883 multi-parameter probe, incorporates a domed shaped pH bulb rated from 0-13 pH,

a single junction Ag/Cl reference electrode with gelled electrolyte and a retractable cloth

wick junction, a graphite EC/TDS cell, and a temperature sensor in one convenient, rugged

polypropylene body. In addition, to ensure against interference from transient electrical

noise to pH, a solid-state pre-amplifier is integrated into the probe. The probe is rated

from 0 to 50°C.
