Rustrak 3" Strip Recording Chart Paper with Grids B-7893, 2-12 pH, Non-Uniform Grid

Rustrak B-7893 is a pressure-sensitive strip chart paper that enhances data recording and analysis to easily record temperature, pH, voltage, and current over a certain amount of time, making impressions directly on the paper without needing ink. 

Designed for precision, these long strip charts are in a convenient rectangular shape, perfect for easy integration. This design facilitates easy comparisons and detailed trend analysis when observing patterns, including rising, falling, or stable values.

The continuous recording feature enables users to track changes over time accurately with a pre-printed grid pattern in gray ink. These grids help interpret the recorded data by providing a visual reference for measurements and time intervals. 

The pH scale ranges from 2 to 12 and is categorized as a non-uniform scale. It records pH values across the spectrum, which spans from 2, representing highly acidic substances, to 12, which denotes highly basic or alkaline substances. This design allows for accurate readings of pH levels in different solutions.

The grid lines are gray in color and help improve overall chart readability by providing visual clarity and contrast

This specific chart fits Rustrak recorder models 200 and 400.
