The HI-991300 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-991300 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.
Each meter is supplied complete with:
HI-12883 pH/EC/TDS probe with built-in temperature sensor, DIN connector and 1mm cable

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.
