Product Description

The Mini Titrator HI84531 is an advanced laboratory solution for measuring titratable alkalinity in water and wastewater. Utilizing acid-base titration, this automatic mini titrator ensures fast, accurate, and repeatable results critical for water treatment, laboratory analysis, and environmental monitoring.

This instrument features a highly precise piston dosing pump, dynamically adjusting titrant volume based on voltage changes, coupled with a built-in magnetic stirrer at 600 rpm for uniform sample mixing. The pre-programmed method and robust endpoint detection help ensure that every reading is reliable and accurate, whether you are working with potable water, industrial effluents, or wastewater samples.

  • Automatic acid-base titration and advanced dosing system for rapid, high-accuracy measurements.
  • Measures titratable alkalinity over two ranges: Low (30.0–400.0 mg/L, 0.6–8.0 meq/L) and High (300–4000 mg/L, 6.0–80.0 meq/L).
  • Multiple endpoint titration modes: 8.30 pH (phenolphthalein), 4.50 pH (bromcresol green-methyl red).
  • Sample size: 50 mL, suitable for both high-throughput labs and field applications.
  • USB port facilitates easy data storage and PC export, supporting up to 400 logs (200 titrations, 200 pH/mV readings).
  • GLP-compliant pH measurements, ±0.01 pH accuracy, and broad pH and mV range capabilities.
  • Temperature range of -20.0 to 120.0°C, with high accuracy and robust stainless steel probe included.
  • Glass body, refillable pH electrode with BNC connector for precise titration endpoints.
  • Compact laboratory footprint: 235 x 200 x 150 mm, weight 1.9 kg for ease of placement and portability.
  • Supplied complete with dosing unit, pH electrode, temperature probe, power adapter, and required accessories.

Typical use cases include industrial water treatment, laboratory alkali titration, effluent and wastewater monitoring, and quality control in environmental, municipal, and commercial sectors.
