Learn how to use the Fellow Series 1 water hardness test strip to check mineral levels during setup and maintenance, ensuring optimal espresso extraction.
Quick Answer
To use the Series 1 water hardness test strip, dip it in your water sample, wait for the color to develop, and compare it to the chart to determine your water hardness level.
Why Water Hardness Matters for Your Espresso
Water hardness affects how your espresso extracts. Hard water can lead to scale buildup inside your machine, while soft water may result in under-extracted, sour shots. The Series 1 water hardness test strip helps you measure mineral levels so you can adjust your water or descaling schedule accordingly.
The test strip is designed specifically for use with the Espresso Series 1, making it a convenient tool during initial setup and routine maintenance. Knowing your water hardness helps you maintain consistent brew quality and prolong the life of your machine.
Step-by-Step Guide to Using the Test Strip
- Prepare a water sample: Fill a clean glass with water from the same source you use for brewing. Ensure the water is at room temperature (around 20°C/68°F) for accurate results. Do not use hot or cold water, as temperature can affect the test result.
- Dip the test strip: Remove one test strip from the package and dip it into the water sample for about 2 seconds. Make sure the test pad is fully submerged. Do not leave the strip in the water longer than recommended, as it may cause inaccurate color development.
- Wait for the color to develop: Remove the strip and shake off excess water. Wait for the specified time (usually 30-60 seconds) for the color to stabilize. Do not wait too long; reading after the recommended time can give a false result.
- Compare the color: Hold the test pad next to the color chart on the packaging. Match the color to the nearest hardness level (e.g., soft, medium, hard). Use good lighting to avoid misreading the color.
- Record and act on the result: Note your hardness level and adjust your water treatment or descaling schedule accordingly. For example, if your water is hard, consider using filtered water or descaling more frequently. Keep a log of your readings to track changes over time.
