Biological samples such as blood, saliva, cerebrospinal fluid, tissue fluid, etc…cannot be sampled in large quantities. Usually such small quantities of samples require the purchase of expensive ultra-small glass electrodes of pH meter to perform the test. UH1 can provide the perfect solution by dripping sample, or by dipping. *UH2 can provide sample requirements as small as 1 microliter (Learn about UH2)
Body fluid (perspiration) detection
Fermentation process control
A brand-new test strip can be taken from the vial for each use and requires no time-consuming cleaning or maintenance after testing. For viscous or easily adsorbed samples or in combination with various special treatments, it breaks through the limitations of traditional glass electrodes and provides you with more applications.
Allows special treatment such as sterilization and inactivation
Test viscous samples that are difficult to clean up
We provide high precision pH measurement. The values can be displayed to 0.01, and the accuracy can reach ±0.1 pH. Testing pH values from 0 to 14 can be satisfied.
The reference liquid leakage problem is avoided with our unique design for screen-printed electrode with ion membrane. You don’t need to worry about the reaction between reference electrode and your samples, such as protein samples. Thus, it is suitable for continuously monitoring for long time and applying in a wider range of samples.
The thickness of traditional glass electrode’s glass film is only 0.1-0.3mm, so it is easy to break. For storage, it needs to be continuously immersed in liquid storage solution, so special care is needed for carrying. The special design of the Humming Probe does not contain any filling liquid. Small size, portable, just put it in the vial with a tight lid, suitable for mobile outdoor testing environment.

In terms of quality control, the production of all test strips and instruments is performed by UltraE. In addition to accurately mastering the production technology, we also control the product quality throughout the process. The test strips start from the raw material, through the substrate bare chip printing, to the high polymer film process and temperature sensor assembly process, and follows 100% full inspection process to ensure product stability. We are also officially ISO 9001:2015 certified, assuring our partners of quality and standardized processes.
All products are calibrated and inspected using NIST traceability standards before leaving the factory, and each batch of calibration information is printed as QR code on the cap of the vial. Scan the QR Code when using the strip for the first time to load the technical parameter of the pH strip into the meter, and then the pH measurement can be performed directly.Unlike traditional glass electric appliances, the Humming Probe is extremely convenient, not requiring traditional and complicated calibration steps.
Measuring method 1
Take the pH strip electrode out from the vial.
Measuring method 1
Test by directly dropping samples onto the strip
method 2
Put the pH strip electrode into the sample solution.
The pH value for culture media or buffer solutions are usually adjusted to within 0.1 pH. Our product, the Humming Probe, is able to monitor the pH value of culture media at any time by directly insertion to make sure the cells and bacteria are growing under the correct environment.
Traditional methods of monitoring outdoor environmental pollution often require samples to be taken to the laboratory for testing. Direct on-site testing is rarely used, and it often takes a long time to detect pollution problems. The Humming Probe pH Measurement System does not require you to carry a variety of calibration solutions, only requiring the pH meter and the pH strips, to perform direct on-site testing. The test results can be obtained quickly, the testing time can be greatly shortened, and the degree of pollution can be understood immediately.
Colorimetric methods to measure are commonly used instead of traditional pH meter, due to the low volume of biomedical samples such as blood, urine, or interstitial fluid. However, colorimetric methods are often difficult to obtain accurate data. In contrast, our Humming Probe only requires 1-20 μL volume of sample to perform testing. Moreover, the Humming Probe System can be integrated with other detection sensors through customization.
The acidity and alkalinity (pH) of the soil is an important step in planting crops. The Humming Probe pH Measurement System can test soil pH directly in moist soil or using a simple water-soluble medium to assist in plant growth management or soil improvement.
In the process of producing food, pH value will affect the taste, freshness, and shelf-life of the final product. The design of the patented ionic membrane and disposable electrode of the Humming Probe pH strip can overcome the complex composition of the sample, which usually requires a pre-treatment process to accurately measure to provide accurate pH measurements for meat, fish, jam, seafood, milk, cheese, yogurt, dairy products, sauces, teas, etc.
No matter if you are doing organic, non-organic or polymer synthesis experiments, it is necessary to control the pH value in every phase under different reaction conditions. The Humming Probes pH meter can be directly dipped into small samples at different stages to obtain accurate pH values. Its disposable design can also avoid impurities on the electrodes or introducing contaminants to the system.
