How They Work
The Kalstein Benchtop Turbidity Meter YR01842 functions using infrared light at a wavelength of 850 nm, which scatters upon encountering particles in the sample solution. The degree of light scattering correlates to the turbidity level, which is displayed on its backlit LCD screen. This model offers two-point calibration for enhanced accuracy.
The Lovibond TB 300 IR also detects turbidity through the scattering of infrared light, utilizing a wavelength of 880 nm. It provides multi-point calibration that adjusts to various standards of measurement, although it may require more frequent calibration checks compared to the Kalstein model.
Purpose and Application
Both products are vital in measuring the turbidity levels in water and other fluids. They are primarily used in water treatment facilities, food and beverage industries, and laboratories involved in chemical testing. Precise turbidity measurement is critical for maintaining regulatory compliance and ensuring quality control across numerous applications.
Types
Turbidity meters, like the ones from Kalstein and Lovibond, come in different types largely defined by their field of use: portable, handheld, and benchtop models. The Benchtop models typically offer more precise and stable readings, which is why they are preferred in laboratory settings.
Market Price
The Kalstein Benchtop Turbidity Meter YR01842 is competitively priced in the market, generally ranging from $500 to $700, depending on the retailer and location. On the other hand, the Lovibond TB 300 IR sits within a similar price range but may vary slightly based on its availability and demand in certain regions.
Frequently Asked Questions
What is the standard warranty offered for each product?
Both products typically come with a one-year warranty, but it is advisable to verify with the supplier as conditions may vary.
Can these meters measure turbidity in seawater?
Yes, both meters can measure turbidity in seawater, though calibration against standards specific to seawater is recommended for best results.
Are there any specific maintenance routines required?
Regular cleaning of the sample cuvettes and periodic calibration checks are recommended to maintain the accuracy of both turbidity meters.
Advantages and Disadvantages
The Kalstein YR01842 offers several advantages, such as a user-friendly interface, durable build, consistent accuracy with two-point calibration, and flexible power options with both battery and AC adapter use. The Lovibond TB 300 IR, while also reliable, has a robust design and supports multi-point calibration, though it might require more frequent calibration adjustments and relies solely on battery power.
Field Usage
In practice, the Kalstein YR01842 is widely used in research labs and industrial settings where prolonged use is expected, thanks to its sturdy design and accurate, repeatable readings. The Lovibond TB 300 IR serves well in more mobile scenarios where easy deployment is necessary, although its reliance on batteries may be seen as a limitation in long-term fieldwork without adequate power sources.
Recommendations
For optimal use of the Kalstein YR01842, it is recommended to integrate it into a stable laboratory setup with access to AC power to maximize its continuous operation capabilities. Regular calibration as per the manufacturer’s guidelines will ensure sustained accuracy.
