How They Work
The Kalstein Portable Ph/DO Meter YR06381 operates with a highly sensitive electrode to detect hydronium ion concentration, giving precise pH readings. For DO measurements, it uses a Clark-type electrode, which is perfect for measuring oxygen levels in various aqueous solutions. The simplicity of its interface allows users to switch between modes effortlessly, ensuring swift data acquisition.
On the other hand, Hanna Instruments’ HI98193 employs optical technology for its DO measurements, which involves the use of a light sensor to determine the amount of oxygen. This method reduces the need for frequent recalibration and maintenance, providing stable readings over time. Its advanced features accommodate meticulous scientific research and industrial applications.
Purpose
Both the Kalstein YR06381 and Hanna Instruments HI98193 serve the critical function of monitoring the pH and dissolved oxygen levels in various environments. These parameters are essential in fields such as environmental science, aquaculture, and water treatment. Accurate pH and DO readings are vital for maintaining chemical balance, ensuring organism health, and optimizing industrial processes.
Types
Within the category of pH/DO meters, there are primarily two types: portable and benchtop. Products such as the Kalstein YR06381 and Hanna HI98193 belong to the portable category, offering flexibility and ease of use in field operations. Benchtop models, while typically more robust, are designed for stationary laboratory use where higher resolution measurements are necessary.
Market Pricing
The pricing for portable pH/DO meters can vary widely depending on the features and brand reputation. The Kalstein YR06381 is known for its competitive pricing, offering excellent value for money given its high performance and durability. Conversely, the Hanna HI98193 is positioned at a higher price bracket, reflecting its advanced optical technology.
