Hanna Instruments Digital Glucose Refractometer HI96803

The Hanna Instruments HI96803 digital glucose refractometer was specially developed for the precise determination of glucose content in various liquid samples. Especially in laboratories in the food, pharmaceutical and beverage industries, this model offers a clear advantage over comparable devices due to its short measurement time and high accuracy. Similarly equipped measuring devices such as the [Hanna Instruments Digital Honey Refractometer HI96801] are used in similar areas, but the model described here is optimally designed in terms of specialization for glucose measurements and handling.

Precise measurements for demanding applications

This digital handheld refractometer provides measurements from 0 to 85% by mass glucose and impresses with a resolution of 0.1% by mass with an accuracy of ±0.2% by mass. Thanks to the automatic temperature compensation in the range from 0 to 40 °C, users can rely on reproducible values at all times, even under changing ambient conditions.

In addition to the wide measuring spectrum, the robust IP65 housing and the fast measuring time of around 1.5 seconds ensure very high efficiency. Only 100 µL of each sample needs to completely wet the prism, which means that even the smallest quantities of a solution are sufficient. In addition to its resistance to dust and splash water, this particularly appeals to users in quality assurance or for mobile measurements, where reliability and speed are key factors.

The materials used – a lead glass prism and a stainless steel ring – are deliberately designed for durability and optimum light refraction. This is supported by the yellow LED light source, which ensures precise evaluations. It is also easy to read and adjust the measurement at any time, as the device measures the temperature in steps of 0.1 °C or 0.1 °F and automatically corrects the result accordingly. After three minutes of inactivity, the refractometer switches itself off, which saves battery power, especially on longer measurement routes in large laboratory environments or directly on site in production areas.

Technical highlights at a glance

– Glucose measuring range: 0 to 85 mass%
– Resolution: 0.1 mass%
– Accuracy: ±0.2 mass%
– Measuring time: ≈ 1.5 seconds

The remaining features such as the 9V block battery system (with a capacity of around 5000 measurements) and the housing made of durable plastic emphasize the design for tough laboratory conditions and prolonged use. With dimensions of 192 x 102 x 67 mm and a weight of just 420 g, the device is easy to transport and handy enough to be used for on-site inspections.

Certifications and standards

The IP65-compliant housing meets requirements for dust-tightness and protection against water jets from all directions. Such handheld refractometers are also usually CE-compliant. The device therefore offers sufficient safety and a high level of resistance to external influences.

Concrete application examples

– Food industry: For checking the sugar or glucose content in syrups, confectionery, fruit juices and caramel sauces
.- Beverage production: Measurement of the sugar content in soft drinks or beers during the brewing process to monitor fermentation.
– Pharmaceutical research: To determine exact glucose concentrations in the development of special solutions.
– Quality control in laboratories: Regular random sample analysis of various sugar solutions, for example for the incoming inspection of raw materials.

The device offers fast feedback with consistently high user-friendliness, especially for highly concentrated solutions with melted sugars or fermented beverages. Substances such as glucose syrup or dextrose are also frequently analyzed using the refractometer in order to control processes and comply with quality standards.

FAQs

How do I maintain and clean the measuring prism correctly?

The prism is made of lead glass and should be rinsed with distilled water or a mild cleaning solution after each measurement. Then wipe dry to avoid the formation of deposits.

Can I also use the device at widely varying temperatures?

Yes, the automatic temperature compensation adjusts to values between 0 and 40 °C, ensuring precise glucose measurement even in changing temperature zones.

How often do I need to calibrate the refractometer?

If the device is used regularly, it is advisable to check it daily or with a reference solution for critical measurements. Longer downtimes or changes of location increase the need for calibration.

What happens if the device is not used for a longer period of time?

After three minutes of inactivity, the refractometer switches off automatically to save the battery. If the device is not used for a longer period of time, it is advisable to remove the battery to prevent self-discharge.

Conclusion

The device presented here impresses with its robust design, reliably high measurement accuracy and fast determination of glucose concentration, making it ideal for laboratories, food production and beverage production. Thanks to the IP65-protected housing and ease of use, the handheld refractometer can be used flexibly in many areas and offers specialist users an extremely practical solution for reliable glucose measurement.
