PH measurements are essential to maintaining quality and accuracy in numerous laboratory procedures. Kalstein models of portable PH meters are industrial instruments designed to meet these demands with excellence and precision. In this article, we will discuss the technical specifications and features of these instruments.
Kalstein Models YR01800 and YR01800-1
These meters have a pH range of -1.00 to 15.00, which means they can handle a wide range of acidity and alkalinity levels. With a resolution of 0.01 pH, these models provide highly accurate results, with an accuracy of ± 0.01 pH. This ensures consistent and reliable measurements in every use.
The YR01800 and YR01800-1 models have the ability to calibrate from 1 to 3 points using either US (pH 4.01 / 7.00 / 10.01) or NIST (pH4.01 / 6.86 / 9.18) pH buffer options. This provides flexibility and accuracy in calibration according to the needs of the laboratory. In addition, they have a manual or automatic hold function to save the measurements at the end, thus avoiding data loss. https://www.kalstein.nl/product/pocket-ph-meter-c-f-yr01800-yr01800-1/
Kalstein models YR01802 and YR01802-1
Like the previous models, these meters have a pH range of -1.00 to 15.00 and a resolution of 0.01 pH, providing high precision measurements with an accuracy of ± 0.01 pH. They also allow 1- to 3-point calibration and offer U.S. or NIST pH buffer options.
A useful feature of the YR01802 and YR01802-1 is their automatic shut-off after 8 minutes of inactivity, an energy-saving feature that increases the life of the device. They also feature a two-line LCD monitor for clear and easy reading of measurements. https://www.kalstein.nl/product/pocket-ph-meter-c-f-yr01802-yr01802-1/
Kalstein Model YR01804
Model YR01804 also has the same measurement and calibration capabilities as the previous models. However, this model has an additional feature: temperature compensation capability from 0 to 100 °C (32 to 212 °F). This allows for accurate pH measurements over a wide temperature range.
This model also has a manual or automatic standby function and a reset function, making it easy to use and operate. In addition, the YR01804 includes a BNC-type connector, which provides a secure and reliable connection for signal transmission. https://www.kalstein.nl/product/pocket-ph-tester-yr01804/
Kalstein YR0220A and YR0210A Models
The YR0220A and YR0210A models have a pH range of -2,000 to 20,000. These devices also allow high selectable resolution, ranging from 0.001 pH to 0.1 pH, ensuring accuracy in measurements. The ability to calibrate from 1 to 5 points on these models provides maximum versatility and accuracy.
In addition, both models have a temperature range of 0 to 105 °C / 32 to 221 °F, offering a wide range for accurate pH measurements under varying conditions. They also feature temperature compensation calibration and offset calibration functions. https://www.kalstein.nl/product/portable-ph-meter-yr0220a-yr0210a/
