Hanna Instruments tablet meter edge DO HI2004
The Hanna Instruments edge DO HI2004 tablet meter enables precise measurements of dissolved oxygen (DO) in demanding environments. Thanks to its ultra-slim design, intuitive user interface and digital sensor technology, it is particularly suitable for professional applications where high accuracy and flexibility are required. The wireless docking station, which simultaneously charges and stabilizes the device, enables both stationary and mobile measurements. Compared to similarly equipped products such as the Knick Portavo 908, the edge DO HI2004 is particularly user-friendly and versatile.
Performance features and benefits
The device is equipped with the HI764080 polar graphic DO measuring probe, which is characterized by automatic detection and transfer of calibration data. Users can benefit directly from changing the measurement environment without having to perform calibrations again. Similar to the WTW Oxi 3310, the edge DO HI2004 has a compact probe design that is also ideal for measurements in confined sample containers such as wine bottles. Thanks to replaceable PTFE membrane caps (two included) and high-quality refill electrolyte, the service life of the probe can also be extended.

The slim design of the probe (12.7 mm diameter) allows effortless depth measurement in narrow measuring vessels. In addition, the large, user-friendly display continuously provides all relevant measurement information. The integrated data memory and comprehensive logging and transmission functions also make it easier to document measurement series and ensure complete traceability.
Special features
This model stands out with its automatic sensor recognition and digital data transmission. The device takes calibration data directly from the probe, which reduces potential sources of error. The Clark-type membrane technology also ensures fast response times and reliable repeatability. The wide measuring range makes the edge DO HI2004 ideal for a wide range of industries such as environmental analysis, food and beverage testing and laboratory applications.
Certifications and standards
The device is used for professional measuring tasks and complies with the current CE directives. It can be used in ISO-certified laboratory environments and quality-relevant processes when used correctly in accordance with the manufacturer's specifications.
Examples of use
- In wineries for checking the dissolved oxygen content directly in wine bottles
- In breweries for continuous quality control of beer and other malt beverages
- In research laboratories for monitoring microbial processes in nutrient solutions
- In water analysis when monitoring surface or waste water for oxygen saturation
Wherever precise DO measurements are required under changing conditions, the device proves to be a reliable choice.
FAQs
