The Lutron PH-222 is a pen-type pH meter designed for portable and convenient pH measurement. It includes an electrode and offers a measurement range of 0 to 14 pH with a resolution of 0.01 pH. The device achieves an accuracy of ±0.2 pH after calibration using the PE-12 electrode. It also measures temperature from -5 to 80°C with a resolution of 0.1°C/0.1°F. The PH-222 features a built-in temperature sensor and automatic temperature compensation (ATC). It is rated IP67, making it waterproof and protected against dust. The meter has a high input impedance, a dual-display LCD with a bar graph indicator, data hold, auto power-off, and max/min recording with recall. It is powered by four AAA batteries.

Available on EnvMart, these pH Meters are designed with advanced sensor technology to ensure accurate and reliable pH level measurements across various applications. Lutron pH Meters are trusted for their precision, durability, and ease of use, making them ideal for laboratory, industrial, and environmental monitoring.
