The HI-991301 is a lightweight, 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.

Benefits

  • Simultaneous, pH, EC/TDS and temperature measurements on a large three-line LCD display
  • Selectable temperature unit
  • pH electrode condition display
  • mV of pH measurement for electrode check
  • Last calibration points pH and EC
  • HI-12886 dedicated pH/EC/TDS/temperature probe
  • Probe quick connect system
  • Battery life indication and low battery detection
  • Auto-off function
  • Keystroke confirmation tone
  • Waterproof casing IP67

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.

The HI-12886 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℃.

Each meter is supplied complete with:

  • HI-12886 pH/EC/TDS probe with a built-in temperature sensor, DIN connector and 1mm cable
  • pH 4.01 & 7.01 buffer sachets
  • HI-70030 12880 µS/cm and HI-70038 6.44 ppt calibration solution - 1 sachet of each
  • HI-700601 Electrode cleaning solution (2 sachets)
  • 100ml beaker
  • Alkaline batteries: 1.5V AAA x 3
  • Rugged carrying case
  • Calibration certificate of meter
  • Calibration certificate of probe
  • Instruction manual
