Overview<\/h4>\n

The ADWA AD111 is the benchmark portable multi-parameter meter for professionals who need reliable, accurate measurements of pH<\/strong>, ORP (Oxidation-Reduction Potential)<\/strong>, and Temperature<\/strong> in a single lightweight instrument.<\/p>\n

Manufactured by ADWA Instruments<\/strong> \u2014 headquartered in Szeged, Hungary with production facilities in Romania \u2014 the AD111 combines European engineering precision with outstanding cost-efficiency. It is the preferred choice for water quality laboratories, environmental monitoring, aquaculture farms, swimming pool management, food and beverage QC, and educational institutions across Egypt and the Middle East.<\/p>\n

Available from Eagle Systems for Supplies<\/strong>, Cairo, with same-day dispatch and fast delivery across Egypt.<\/p>\n

\n

What Makes the AD111 the Right Choice?<\/h3>\n

Egypt’s diverse water chemistry \u2014 from Nile-fed municipal supplies to industrial process water and agricultural irrigation \u2014 demands a meter that handles extreme pH ranges and fluctuating temperatures without compromising accuracy. The AD111 delivers on all three:<\/p>\n

1. Three Parameters in One Device<\/strong> Unlike basic pH-only meters, the AD111 measures pH, ORP (mV), and Temperature simultaneously. This eliminates the need for separate instruments, saves bench space, and reduces calibration time.<\/p>\n

2. True \u00b10.02 pH Accuracy<\/strong> With \u00b10.02 pH resolution and automatic temperature compensation (ATC), the AD111 produces results that meet the demands of certified laboratories and quality-control environments \u2014 not just basic field checks.<\/p>\n

3. Auto-Buffer Recognition<\/strong> The 2-point push-button calibration automatically recognises standard buffer solutions at pH 4.01, pH 7.01, and pH 10.01. No manual entry required \u2014 the meter identifies the buffer and adjusts calibration instantly.<\/p>\n

4. Complete Out-of-the-Box<\/strong> The AD111 is supplied with every accessory needed for immediate operation: pH electrode (AD1230B), stainless steel temperature probe (AD7662), calibration buffer sachets (pH 4.01 and pH 7.01), four AA alkaline batteries, and a full user manual. Nothing additional to purchase before your first measurement.<\/p>\n

5. Auto-Off Battery Conservation<\/strong> The meter powers off automatically after 8 minutes of non-use<\/strong>, significantly extending battery life in field conditions where accidental power-on is common.<\/p>\n

    How to Use the ADWA AD111 \u2014 Quick Guide<\/h3>\n

    Taking a pH measurement:<\/strong><\/p>\n

      \n
    1. Remove the electrode tip protector and rinse with distilled water.<\/li>\n
    2. Press MODE<\/strong> to select pH mode.<\/li>\n
    3. Submerge the electrode in the sample \u2014 avoid air bubbles.<\/li>\n
    4. Wait for the HOLD<\/strong> indicator to appear (stable reading).<\/li>\n
    5. Record the displayed pH value.<\/li>\n<\/ol>\n

      Calibrating the pH electrode:<\/strong><\/p>\n

        \n
      1. Prepare a fresh pH 7.01 buffer solution.<\/li>\n
      2. Submerge the electrode and press CAL<\/strong>.<\/li>\n
      3. The meter auto-recognises the buffer and adjusts \u2014 confirm with ENTER<\/strong>.<\/li>\n
      4. For 2-point calibration, repeat with pH 4.01 or pH 10.01 buffer.<\/li>\n<\/ol>\n

        Taking an ORP (mV) measurement:<\/strong><\/p>\n

          \n
        1. Press MODE<\/strong> to switch to mV\/ORP mode.<\/li>\n
        2. Submerge the electrode (ORP-capable electrode required).<\/li>\n
        3. Allow the reading to stabilise \u2014 use HOLD<\/strong> to freeze.<\/li>\n<\/ol>\n
          \n

          Tip:<\/strong> Always rinse the electrode with distilled or deionised water between samples to prevent cross-contamination.<\/p>\n<\/blockquote>\n

          Choose AD111<\/strong> if you need ORP \/ redox potential measurement \u2014 for water disinfection control, aquaculture, or oxidising\/reducing process monitoring.<\/p>\n

          Choose AD110<\/strong> if pH and temperature measurement is sufficient for your application and budget.<\/p>\n

          \n

          Frequently Asked Questions (FAQ)<\/h3>\n

          Q: Can the AD111 measure saltwater or seawater?<\/strong> A: Yes. The wide pH range of \u22122.00 to 16.00 accommodates saline, alkaline, and acidic solutions, including seawater, industrial effluents, and chemical process waters.<\/p>\n

          Q: How often should I calibrate the AD111?<\/strong> A: For general use, calibrate before each measurement session or at a minimum daily. In critical applications (pharmaceutical, food QC), calibrate with each use. Always use fresh, unexpired calibration buffers.<\/p>\n

          Q: Can I replace the pH electrode?<\/strong> A: Yes. The AD111 uses a standard BNC connector \u2014 the AD1230B<\/strong> replacement electrode is available from Eagle Systems. Other ADWA-compatible BNC electrodes also work.<\/p>\n

          Q: What is ORP \/ Redox potential and why does it matter?<\/strong> A: ORP (Oxidation-Reduction Potential) measures the ability of a solution to oxidise or reduce substances. In water treatment, ORP directly indicates the effectiveness of disinfectants such as chlorine and ozone. A positive ORP indicates oxidising conditions; a negative ORP indicates reducing conditions.<\/p>\n

          Q: Is the AD111 waterproof?<\/strong> A: The AD111 is splash-resistant but not fully waterproof\/submersible. Avoid submerging the main unit. The electrode and temperature probe are designed for immersion in liquid samples.<\/p>\n

          Q: Does Eagle Systems offer calibration services for the AD111?<\/strong> A: Yes. Eagle Systems provides calibration verification services and can supply certified NIST-traceable calibration buffers for critical applications. Contact us for details.<\/p>\n

          Q: What is the warranty on the ADWA AD111?<\/strong> A: The AD111 carries a 1-year manufacturer warranty<\/strong> against manufacturing defects. Eagle Systems handles all warranty claims in Egypt \u2014 you do not need to contact the manufacturer directly.<\/p>\n

          Q: Is the ADWA AD111 suitable for use in Egypt’s climate?<\/strong> A: Yes. The operating temperature range of \u22125\u00b0C to 105\u00b0C and the automatic temperature compensation make the AD111 fully suitable for Egypt’s high-temperature environments in both laboratory and outdoor field conditions.<\/p>\n
