Details
Double Junction pH Electrode
The HI84533U-01 is supplied with the HI1131B glass body pH electrode. This electrode is refillable and features a double junction, minimizing the contamination of the electrode. This versatile electrode has a spherical sensing glass bulb that provides a wide surface of contact with a wine or fruit juice sample. The sensing portion is composed of high temperature glass, making it ideal for direct measurements or titrations in the beverage industry.
Piston Driven Dosing Pump
The heart of the HI84533U-01 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 HI84533U-01 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 HI84533U-01 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 HI84533U-01 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 analyzes 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 HI84533U-01 is used as a pH meter, but also an accurate titration since the endpoint of a total acidity titration is determined by a set pH value.
