Hanna HI98164 Professional Portable Yogurt pH Meter

Description

An Advanced Meter for Yogurt Quality

The Hanna HI98164 is a professional, waterproof pH and temperature meter designed specifically for the yogurt industry. This rugged, portable device uses the specialized FC2133 pH electrode to ensure accurate measurements, which are crucial for producing consistent and high-quality yogurt. The device comes with all the necessary accessories, including calibration buffers and cleaning solutions, neatly packed in a durable, thermoformed carrying case, making it perfect for on-site use. The HI98164 simplifies the process of pH monitoring, providing a reliable tool that complies with IP67 standards.

Why pH Matters in Yogurt Production?

Monitoring pH is a fundamental aspect of producing consistent, quality yogurt. Yogurt is created through the fermentation of milk with live bacterial cultures. After adding a starter culture, the milk and bacteria mixture is incubated, leading to the production of lactic acid from lactose. This process causes the pH to drop and the mixture to become more acidic, which in turn causes the casein protein in milk to coagulate, resulting in the characteristic yogurt texture. By carefully controlling the pH level, producers can stop fermentation at a predetermined endpoint, ensuring consistent flavor, aroma, and texture in their products.

A Specialized Probe for Difficult Samples

The HI98164 comes equipped with the FC2133 amplified pH electrode, a probe specifically engineered to handle the challenges of measuring pH in yogurt. Yogurt is a semi-solid with a high-solids content, which can easily coat the sensitive glass membrane and clog the reference junction of a standard pH electrode. The FC2133 addresses this with a conical tip for easy penetration into semi-solids and an open junction design that resists clogging. This ensures fast, stable, and accurate readings, making the meter ideal for its intended application.

Advanced Features for Reliable Results

The HI98164 meter includes a range of advanced diagnostic and operational features to improve the reliability of measurements. The CAL Check™ feature is a vital tool that alerts the user to potential problems during calibration, such as when the electrode needs cleaning or if the pH buffer is contaminated. The device also offers an AutoHold function that freezes a stable reading on the screen and a Log-on-demand mode to save up to 200 samples. Comprehensive GLP (Good Laboratory Practice) data, including date, time, calibration buffers, and slope, is automatically stored with logged data for traceability.

A User-Friendly Interface for All

The Hanna HI98164 is designed for easy and intuitive operation. Its high-contrast, graphic LCD screen is easy to read in both bright sunlight and low-lit areas due to its backlight feature. A combination of dedicated and virtual keys allows users to navigate the menu and access various functions, including a contextual help menu, which can be accessed at any time with the press of a button. The meter also offers multiple language options for messages and on-screen instructions.

Portable and Durable Design for Field Use

The Hanna HI98164 is built for durability and portability. Its rugged, ergonomic design and waterproof IP67 rating make it suitable for use in demanding production environments. The compact HI720161 carrying case is thermoformed to securely hold all the necessary components for field measurement, including the meter, electrode, beakers, and solutions. This design allows users to easily carry the meter and perform tests wherever they are needed on the production floor.
