Product Description
The YR01821 pH Meter is a highly advanced laboratory instrument designed to provide accurate and reliable pH measurements. This device offers a broad measuring range from (-2.00 to 20.00) pH, making it suitable for a wide array of applications, from simple laboratory experiments to complex industrial processes. It boasts a resolution of 0.1/0.01 pH and an impressive accuracy of 0.01/0.001 pH, ensuring that every reading is precisely captured.
Equipped with an automatic calibration feature, the pH meter supports 1, 2, and 3-point calibration using a variety of standard buffers, including those from Europe & USA, NIST, and China standards. Its input current threshold of ≤2×10¹² A and input impedance of 21×100 guarantee stable and consistent performance.
One of the standout features of the YR01821 is its temperature compensation capability, which can be set between 0~100°C, either automatically or manually, thus optimizing measurement accuracy regardless of environmental conditions. The meter is extremely robust with a stability of ±0.01 pH over three hours, and it features a 6.5-inch LCD screen for clear display and ease of use.
Data storage capability allows for up to 1000 sets of measurements to be stored, while a DC 12V/1A power supply and USB output make it adaptable to various laboratory settings. The device functions optimally in temperatures ranging from 5~40°C and humidity below 85%, and has an IP54 protection rating, providing resistance against dust and splash water.
