The Hydrion 2210 Short-Range pH Paper Dispenser from Micro Essential Laboratory provides a quick visual method for checking solutions between pH 4.5 and 8.5. Unlike broad-range pH paper that covers most or all of the pH scale, Hydrion 2210 concentrates its colour chart around the acidic-to-alkaline range surrounding neutral pH 7.0, with readings at 0.5 pH intervals.
The dispenser contains a 15 ft roll of pH test paper and a matching colour chart. Tear off only the amount of paper required, expose it to the sample, and compare the resulting colour with the chart. This makes the 2210 useful for fast routine pH screening in general laboratories, industrial testing, food service, agriculture, education and other applications where an immediate visual pH check is more practical than setting up a meter.
| Feature | Why It Matters |
|---|---|
| pH 4.5–8.5 range | Focuses the colour scale around neutral pH, making it better suited to near-neutral samples than a general full-range paper. |
| 0.5 pH reading intervals | Provides closer visual differentiation than many broad-range papers that use full pH-unit steps. |
| ±0.25 pH stated accuracy | Micro Essential states this accuracy for its short-range pH papers with half-unit intervals, making the format useful for routine screening where instrument-level measurement is not required. |
| 15 ft dispenser roll | Allows the user to tear off only the amount required for each test rather than using a fixed-size strip. |
| Matching colour chart included | No electronic meter, batteries or meter calibration are required for routine visual checks. |
| Approximately 100–150 tests per standard roll | A convenient format for repeated spot testing. Actual test count depends on how much paper is used for each test. |
The Hydrion 2210 colour chart provides individual matches throughout the 4.5–8.5 range:
This narrower range is particularly useful when the expected result is reasonably close to neutral pH and a full 0–14 scale would provide more range than is required.
| Application | How Hydrion 2210 Helps |
|---|---|
| General Laboratories | Provides a fast visual check when determining whether an aqueous sample falls within the 4.5–8.5 pH range. |
| Industrial QA/QC | Useful for quick process or sample screening before deciding whether more precise instrumental measurement is required. |
| Food & Beverage | Provides a simple pH spot check for compatible liquid samples within the specified range where visual colour comparison is suitable. |
| Water & Environmental Screening | Can provide a quick indication of whether a sample is acidic, near neutral or alkaline within the 4.5–8.5 range. |
| Agriculture | Suitable for general-purpose testing where the sample and expected pH are compatible with visual pH paper. |
| Education | The colour-change method provides an easy way to demonstrate acidic, neutral and alkaline conditions without electronic instrumentation. |

| Testing Need | Consider |
|---|---|
| Quick testing between pH 4.5 and 8.5 | Hydrion 2210 is a good fit. |
| More closely spaced readings specifically between pH 5.5 and 8.0 | Consider the Hydrion 067 pH Paper Dispenser, which provides additional colour-chart readings within this narrower range. |
| Unknown sample that may fall well outside pH 4.5–8.5 | A broader-range option such as 0–14 pH Test Strips may be more appropriate for initial screening. |
| Numeric results, greater resolution or repeatable instrument readings | Consider a digital tester such as the Milwaukee pH54 Waterproof pH Tester. |
Store Hydrion pH paper in a dry location away from direct sunlight and check the expiration date printed on the product before use.
Because the result is determined by visually comparing the test paper with a colour chart, strongly coloured samples can make colour interpretation more difficult. A digital pH meter may be more suitable when a visual colour match cannot be read confidently.

Hydrion 2210 is a short-range visual pH paper designed to measure solutions between pH 4.5 and 8.5. It is useful for fast screening in laboratories, industrial testing, food service, agriculture, education and other general-purpose applications.
Micro Essential Laboratory states that its short-range pH papers with half-unit intervals are accurate to approximately ±0.25 pH units. The Hydrion 2210 chart provides readings every 0.5 pH unit from 4.5 through 8.5.
Micro Essential states that a standard 15 ft Hydrion roll generally provides approximately 100–150 tests. Actual yield depends on how much paper is torn off for each test.
Hydrion 2210 covers a wider pH 4.5–8.5 range with colour matches every 0.5 pH unit. The Hydrion 067 covers pH 5.5–8.0 but provides more closely spaced readings within that narrower range. Micro Essential specifically recommends the 067 product for urine and saliva testing.
It can be useful for quick screening when the expected sample pH falls between 4.5 and 8.5. For compliance testing, reporting or laboratory procedures that specify a calibrated pH meter or particular analytical method, follow the required method.
It can provide a quick visual pH check for compatible liquid samples within its 4.5–8.5 range. Where precise numerical results, documented measurements or testing of strongly coloured or difficult samples is required, a suitable food or laboratory pH meter may be a better choice.
Micro Essential Laboratory advises against using Hydrion pH paper for sodium chloride solutions because salt can interfere with the indicator dyes and may produce inaccurate results.
No electronic calibration is required. The colour developed on the test paper is compared directly with the matching colour chart supplied with the dispenser.
Keep the test paper dry and away from direct sunlight. Hydrion pH papers have a manufacturer-stated shelf life of three years from manufacture, and the expiration date and lot information should be checked before use.
Yes. Cambridge Environmental Products supplies Hydrion 2210 to Canadian laboratories, educational institutions, manufacturers and other scientific and production facilities with CAD pricing and Canadian purchasing support.
Let Cambridge know your expected pH range, sample type, required resolution, testing frequency and whether you need a quick visual screening result or a digital instrument reading. We can help determine whether Hydrion 2210, a narrower or broader-range pH paper, or a digital pH meter is the better fit.
