    What is the Humming Probe pH Measurement System ?

    pH calibration solution not required – ready-to-use

    Traditional pH meters can have systematic errors after every use due to variations in the exchangeablehydrogen ions on the glass membrane surface and the hydrogen ion concentration in the glass membrane. Thus, glass electrode must be calibrated for precise measurements. However, every piece of our electrode has already been calibrated, so you can use the humming probe directly ↑
    ....
    Use brand new electrode everytime and no worry about hole contamination or wear on the electrode surface for Calibration-free micro disposable pH electrodes - Humming Probe-UltraE

    Use brand new electrode every time - no worry about contamination

    The wear and tear of the glass electrode often comes from the blockage in the glass membrane or impropercleaning of the glass surface. The disposable design of the Humming Probe is especially suitable for protein samples that will react with the reference solution and for viscous samples that are difficult to clean. In addition, it can also meet the demands for outdoor use and carrying long distances ↑
    ....
    There is no need to use pH calibration standard solution and pH electrode preservation solution for the Calibration-free micro disposable pH acid-base detection electrode / Humming Probe-UltraE

    Temperature sensing element, precise calibration on every strip

    The same pH solution will change its pH at different temperatures due to different dissociation constant,so the temperature compensation mode is used to correct the pH value at different temperatures back to 25℃. Each piece of Humming Probe has an independent temperature sensing element which can accurately measure the sample temperature and make intelligent data compensation to precisely display the pH value of the sample ↑

    Portable, easy storage, no maintenance required

    Humming Probe acid-base detection test strip (pH meter) uses the patented hydrogen ion adsorptionmembrane design to replace the design of the reference electrode in the traditional glass electrode. Therefore, there is no filling liquid, no maintenance required, and no need to store in a preservation liquid ↑
    ....
    Portable calibration-free micro disposable pH electrodes/Humming Probe-UltraE will not break like glass electrodes and doesn't need electrode preservation solution

    International Certification

    UltraE has been officially certified in accordance with ISO 9001:2015 quality management system andobtained the certificate. Comprehensive quality control, automatic equipment production, and strict production process control ensure the accuracy of each inspection. Fully supports the need for GLP certification ↑
    ....
    Calibration-free micro disposable pH electrodes/Humming Probe-UltraE are also officially ISO 9001:2015 certified

    Sample size is down to microliters

    Biological samples such as blood, saliva, cerebrospinal fluid, tissue fluid, etc… cannot be sampled in large quantities.Therefore, the electrode size of the Humming Probe can be reduced to 1 mm, and the sample requirement can be as small as 1 microliter (μL). It is very helpful for situations where extremely small samples are used, especially in the fields of cell engineering, genetic engineering, and life science ↑
    ....
    Calibration-free micro disposable pH electrodes/Humming Probe-UltraE requires only a few microliters or a drop of liquid to complete pH detection/pH test
