Product Description

Hanna HI-84531-02 Total Alkalinity Mini Titrator for Water Analysis

The HI-84531 is an easy to use, fast and affordable automatic mini titrator designed for testing titratable alkalinity levels in water. Based on an acid base titration method, this mini titrator uses an optimised pre-programmed method of analysis with a powerful algorithm that determines the completion of the titration reaction by the use of a glass body pH electrode.

The HI-84531 incorporates a precision piston style dosing pump that adjusts the volume of dosing dynamically based on the voltage change. This dosing system reduces the amount of time required for the titration while providing for a highly accurate determination of the amount of titrant used.

This mini titrator is supplied complete with all the materials necessary to perform low and high range measurements of alkalinity in water. All chemicals are premixed and pre-packaged including standardised titrants, reagents and pump calibration solution. There is no need for volumetric glassware or analytical balances.

Features Hanna HI-84531-02 Total Alkalinity Mini Titrator

  • Piston driven pump for accurate dynamic dosing
  • Complete with glass double junction pH electrode
  • Pre-standardised titrant and pre-measured reagents

About Alkalinity

Alkalinity is the ability of water to neutralise acids. Total titratable alkalinity is a measure of primarily three types of alkalinities present in a water sample: hydroxides, carbonates, and bicarbonates. Alkalinity in water can be the result of contributions from common chemicals including carbonates, bicarbonates, hydroxides, phosphates, borate and organic acid salts.

The alkalinity of a water sample indicates its ability to resist pH change. The amount of alkalinity in water is mostly due to the bicarbonate/carbonate present. A low alkalinity level indicates that the water is susceptible to pH changes, while a high alkalinity level indicates that the water will be able to resist pH changes. Alkalinity can also be used to determine the corrosive capacity of water and can provide an estimation of water hardness.

Double Junction pH Electrode

The HI-84531 is supplied with the HI-1131B refillable, double junction, combination pH electrode. By design, the HI-1131B has a spherical tip for use in aqueous or liquid solutions. This versatile electrode provides a wide surface of contact with a sample and is ideal for direct measurements or acid base titrations in the water industry.

Piston Driven Dosing Pump

The heart of the HI-84531 is the piston driven burette pump. This type of dosing system uses a motor in which each dose is very precisely controlled and the volume dispensed is accurately determined. The piston driven burette is controlled dynamically so that the volume of titrant being dosed is automatically adjusted based on a voltage response of the previous dose. This type of dosing speeds up the titration process by allowing for more titrant to be dosed at the start of the titration and then very small doses as the endpoint is reached.

Automatic Stirrer

The built-in stirrer is automatically maintained at a speed of 600 rpm, regardless of the viscosity of the solution being titrated.

Easy-to-Use Interface – The HI-84531 has an intuitive user design with clearly defined keys and a large screen that is easy to navigate. The meter has a built-in tutorial mode that, when enabled, will walk the user step by step through the titration process. A dedicated HELP key is always available to allow access to content-specific information during both calibration and titration.

Procedure Warnings – Users are warned if there is an error in procedures such as the titration exceeded the maximum volume of titrant.

Graphic Mode – This mini titrator displays in-depth data during titration, including a real-time graph of the titration curve.

Log-on-Demand – The HI84531 allows for data logging of up to 400 samples: 200 titration results and 200 pH/mV readings. Data can be stored and exported to a USB drive or a PC using the USB connection.

pH/mV Meter – In addition to being an automatic titrator, the HI84531 also can be used as a pH/mV meter. As a pH meter, it has many features of a professional grade benchtop including automatic calibration up to three points with four available buffers, a 0.01 pH resolution, accuracy of ±0.01 pH, automatic temperature compensation and comprehensive GLP data.

CAL Check™ Accuracy is always ensured with Hanna’s unique CAL Check feature, which analyses the response of the electrode during the calibration process. Based on electrode response in the buffer, indicators are displayed on screen to alert the user of potential problems during calibration. These indicators include Buffer Contaminated, Electrode Dirty/Broken, and overall probe condition. The CAL Check function not only ensures an accurate pH reading when the HI-84531 is used as a pH meter, but also an accurate titration since the endpoint of a titratable alkalinity titration is determined by a set pH value.
