Industrial pH Controllers and Portable Meters: Uses, Benefits and Technical Comparisons

pH meters and pH controllers are essential laboratory equipment used to measure the acidity or alkalinity of solutions. Kalstein models offer unique features and technical specifications designed to ensure accurate and reliable measurements.

Selecting the right pH controller depends on the level of accuracy required, the complexity of the task and the working environment. Kalstein instruments offer a variety of options to suit different industrial and scientific requirements, ensuring accurate and reliable results every time. The perfect balance between performance, convenience and cost makes Kalstein an excellent choice for high quality laboratory equipment.

Different existing Kalstein modelsย 

Industrial Inline pH Controller YR01838

Model YR01838 has a measuring range of -1.00 to 15.00pH, an accuracy of ยฑ 0.01pH and a resolution of 0.01pH. It is capable of performing from 1 to 3 calibration points and has pH buffer options in US (PH4.01/7.00/10.01), NIST (pH4.01/6.86/9.18) standards.

YR0220A โ€“ YR0210A Portable pH Meter

Both models of portable meters have a range of -2.00 ~20.00pH, but vary in resolution and accuracy. The YR0220A has a resolution of 0.01pH and accuracy of ยฑ0.01pH, while the YR0210A has a selectable resolution of 0.001, 0.01, 0.1pH, and an accuracy of ยฑ0.002pH.

Pocket pH meter YR01804

Finally, the YR01804 pocket meter provides a range of -1.00 ~15.00pH and an accuracy of ยฑ0.01pH.

Technical Comparison: How are they different and what are the similarities?

The main difference between the above models lies in their measurement ranges, resolution and accuracy, number of calibration points and buffer options. The YR0210A and YR01821 models have higher accuracy and resolution due to their ability to select different measurement scales.

In addition, the YR0210A and YR01821 models allow up to 5-point calibration, unlike the other models which have a maximum of 3 points. This fact denotes higher measurement accuracy and reliability.

Despite technical differences, all Kalstein models share design and performance features that ensure measurement reliability and ease of use. All models feature preset buffer selections and calibration points that allow for precise adjustment.
