Hanna Portable Waterproof pH/EC/TDS Low Range Meter - H1991300

The Hanna Instruments HI991300 is a rugged, portable, multiparameter meter designed for accurate water quality testing in environmental, field, industrial, and laboratory settings. It combines pH, electrical conductivity (EC), total dissolved solids (TDS), and temperature measurements into a single handheld instrument—making it an ideal tool for environmental sampling, water analysis, and on-site monitoring of freshwater, aquaculture, wastewater, and process water.

Key Features

  • 4-in-1 Multiparameter Measurement: Simultaneously measures pH, EC, TDS, and temperature using a single rugged probe, streamlining testing workflows and reducing instrument needs. 
  • Durable, Waterproof Design: Built to withstand real-world field conditions with an IP67-rated waterproof housing resistant to dust and water intrusion.
  • Integrated Temperature Compensation: Automatically compensates EC/TDS and pH readings for temperature changes, improving measurement accuracy in fluctuating conditions.
  • Replaceable Quick-Connect Probe: The included HI12883 multiparameter probe houses all sensors in a single polypropylene body and connects easily with a quick-connect DIN connector.
  • Automatic Calibration: One or two-point automatic calibration for pH and one-point automatic calibration for EC/TDS simplifies setup and ensures reliable performance.
  • Large Multi-Level LCD Display: Easy-to-read display shows measured values and calibration indicators at a glance.
  • Portable & Long Battery Life: Lightweight and comfortable for field use, with long battery life and auto-shutoff to conserve power.
  • Complete Testing Kit: Includes calibration buffers for pH and EC/TDS, electrode cleaning solution, batteries, and a rugged carrying case—ready for immediate use.

 

Applications

  • Environmental Monitoring: Field sampling of rivers, lakes, streams, and groundwater for regulatory compliance and pollution assessment.
  • Wastewater & Treatment Plants: Monitoring pH, conductivity, dissolved solids, and temperature in treatment processes and effluent streams.
  • Industrial Water Testing: On-site measurement of process water quality for manufacturing and plant operations.
  • Aquaculture & Aquatic Research: Tracking water chemistry variables crucial to fish health, aquaponics, and research studies.
  • Drinking Water & Environmental Compliance: Routine quality checks for potable water sources and regulatory reporting.
