A15 Mineral Test Pen

Detects mineral content in water and reminds you to replace the water purifier filter. Equipped with 8 LED lights (7 green + 1 red), the effect is stunning and suitable for demonstrations.

Introduction

Product Definition

The A15 Mineral Detection Pen is a portable electronic testing tool specifically designed to measure the mineral content in water samples. It senses the concentration of soluble minerals in water through a probe, and visually reflects the test result through the illumination position of LED lights, helping users assess the mineral level of water quality and assist in evaluating the working status of water purifier filter cartridges.

Product Features

  • Pen-Shaped Integrated Design: The product resembles an ordinary pen in appearance, with a compact structure and simple operation, making it easy to carry at home and outdoors.
  • LED Level Indication: The panel features 8 LED lights (7 green + 1 red). The green lights illuminate sequentially as mineral concentration increases; when the concentration reaches the upper limit of the current range, the red light illuminates.
  • Dual Range Measurement: The LO range (0~40ppm) is suitable for testing RO water purifier output; the HI range (0~400ppm) is suitable for testing ultrafiltration purifier output and water samples with higher mineral content.
  • Filter Replacement Reminder: When testing water purifier output, if the red light illuminates, it indicates that the filter's filtration capacity may have declined and the filter cartridge needs to be replaced promptly.
  • Dual-Scale Indicator Panel: Features both a low-range scale (0, 3, 5, 8, 12, 18, 25, 40) and a high-range scale (0, 30, 50, 80, 120, 180, 250, 400) for intuitive readings.
  • Water Level Line Marking: A water level line is marked on the pen body. When measuring, submerge the water sample to the water level line to ensure consistent testing conditions and stable results.
  • Wide Temperature Range Measurement: Supports water sample temperature measurement from 0~50°C, allowing testing of daily cold and hot water.
  • Portable Power Supply Design: Powered by two standard AAA batteries. The device weighs approximately 45g and is compact in size, making it convenient to carry.

FAQ

Q: What can the A15 Mineral Detection Pen be used to test?
A: It can test the mineral (soluble solid) content in water samples, suitable for various water samples such as RO water purifier output, ultrafiltration purifier output, tap water, and barreled water.

Q: What does the red light illuminating indicate?
A: The red light indicates that the mineral content of the current water sample has reached or exceeded the upper limit of the selected range. When used for water purifier testing, it typically means the filter cartridge needs to be replaced.

Q: How should I choose between the LO range and HI range?
A: Use the LO range (0~40ppm) when testing RO water purifier output; use the HI range (0~400ppm) when testing ultrafiltration purifier output or other water samples with higher mineral content.

Q: Why is it necessary to align to the water level line during measurement?
A: The water level line indicates the optimal immersion depth for the probe, ensuring that the detection electrode is fully in contact with the water sample at a consistent depth, thereby obtaining stable and reliable test results.

Q: Do the batteries need to be replaced?
A: The product is powered by two standard AAA batteries. When the LED lights become noticeably dimmer or fail to illuminate properly, please replace the batteries promptly.

Q: Are there any requirements for the water sample temperature during measurement?
A: The product supports water sample measurement within the range of 0~50°C, so daily drinking water at normal temperatures can be tested without issue.

  • Mineral Content / TDS: Total Dissolved Solids refers to the total amount of dissolved minerals in water, typically expressed in ppm (mg/L).
  • ppm: Parts per million, a concentration unit. 1 ppm represents 1 milligram of dissolved substances per liter of water.
  • RO Water Purifier: A water purification device that uses an RO reverse osmosis membrane, capable of removing most dissolved solids from water. The output TDS value is typically very low (0~40ppm).
  • Ultrafiltration Purifier: A water purification device that uses ultrafiltration membrane technology to remove suspended solids, bacteria, and other impurities while retaining some minerals. The output TDS value is typically in the range of 0~400ppm.
  • Filter Cartridge: The core filtration component inside a water purifier. Its filtration capacity decreases with extended use and requires regular replacement.
  • LED Indicator Light: A light-emitting diode on the product panel used to visually display test results through light position and color.
  • Water Level Line: A reference line marked on the pen body indicating the immersion depth for measurement. The water surface should reach this line during testing.
