How the original gas pH test strip works?

Patented porous gas-exchange hydrogel membrane design

Detect gas sample without pretreatment

Traditional pH measurement usually operates in aqueous phase systems. If you want to know the pH value of volatile substances in the air, you need to dissolve them in solution before measurement. With the porous gas-exchange hydrogel membrane, the pH value of volatile substances can be measured directly by hydrolyzing the gas.

Fast adsorption-desorption gas exchange

Equilibrium is reached in a short time

Traditional methods of collecting gas samples and pretreating into an aqueous solution to detect the pH value cannot continuously detect the change of the gas pH value. The porous hydrogel membrane of the Humming Probe cooperates with the ion adsorption membrane, which can quickly adsorb and desorb the gas to reach an equilibrium state in a short period of time, to provide continuous detection of the pH value of the gas.

Patented hydrogen ion adsorption film design

Precise maintenance of surface-exchangeable hydrogen ion content

We use the patented hydrogen ion adsorption film, in addition to selectively allowing hydrogen ions in the sample to pass through, to avoid the passivation caused by the adsorption of other matrices in the sample on the surface of the electrode and simplifies the sample processing steps. Furthermore, the surface-exchangeable hydrogen ion content in the Nernst equation, which affects the Ek' value, can be precisely controlled by the design of the hydrogen ion adsorption film.

Automated production technology

Make every electrode look "the same"

Automated production machine can quickly introduce R&D results into the production process for the most efficient bridging of R&D and production.The automatic production machine (G1) can achieve a CV value of 3~5% for the production stability of test strips through automated production model. In addition, we have developed different types of automated machines for different manufacturing process requirements, such as temperature sensing component assembly machines, to increase production stability and consistent quality.

Calibration before leaving the factory

Each test strip has been calibrated

Each test strip has been calibrated and verified using NIST traceability standards before leaving the factory, so you can simply take the test strip out of the vial and test pH directly.verified using NIST traceability standards before leaving the factory, so you can simply take the test strip out of the vial and test pH directly.

Each strip is equipped with independent temperature sensing element

Smart temperature compensation for every test

Each test strip is embedded with an independent small-volume temperature sensing element. When the sample temperature is within the range of 10-40 degrees,even with a small quantity of sample, it also has automatic temperature compensation (ATC), and the resolution can reach ±0.01 pH.01pH。

What makes the Humming Probe pH Strip – UH2 GAS
special in addition to being free of calibration?

Disposable Design
A brand-new test strip can be taken from the vial for each useand 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.

Portable and easy storage
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.
