Hangzhou Qiwei Instrument Co., Ltd. is one of the leading manufacturers and suppliers of portable ph tester in China. With a professional production team, we are able to meet the needs of the majority of our customers. Welcome to wholesale bulk portable ph tester in stock here from our factory. We also accept customized orders.
For easy pH screening of appropriate liquid samples in standard laboratory settings, the Portable pH Tester was created. Because of its small size, it is a useful choice for users who require a simple tool to assess water conditions at various sites without having to set up a complete laboratory workstation.
A portable pH tester can be an affordable entry-level solution for regular pH checks for distributors, suppliers of water-testing equipment, sellers of agricultural products, and industrial supply companies. Its usefulness stems from its easy handling, straightforward measuring procedures, and appropriateness for uses that don't need the extra features of a more sophisticated portable pH meter.
If the chosen model satisfies the necessary measurement range and accuracy, typical use cases could include routine process inspections, irrigation water testing, aquaculture water checks, and preliminary water-quality screening.
Business clients can purchase electrochemical equipment from Qiwei, which also takes inquiries about bespoke orders and bulk purchases. Before choosing a product for project use or resale, buyers can ask for quantity-based quotes, standard packaging details, and model specs.
Before placing a bulk purchase for an affordable pH tester for distribution, evaluate the necessary measurement performance, calibration technique, included accessories, and anticipated order quantity. Contact Qiwei to confirm product suitability and request a quotation for your market.
product key technologies
The PHB-1 Portable pH Tester is an intelligent electrochemical measuring instrument designed based on the potentiometric analysis principle. Its working mechanism is mainly as follows: when the pH indicator electrode (such as a glass electrode) and the reference electrode (such as a saturated calomel electrode) are immersed together in the test solution, a chemical galvanic cell is formed. Since the membrane potential of the indicator electrode changes with the hydrogen ion activity in the solution, the total electromotive force of the cell directly reflects the acidity and alkalinity of the solution.
The core components of the instrument adopt high-quality imported integrated circuits screened by long-term aging treatment and are manufactured under strict craftsmanship, ensuring stable working status and reliable repeatability of the instrument in various environments. The operation panel is reasonably laid out with clearly defined keys. The PHB-1 supports both pH and mV measurement, covering conventional analytical requirements from strong acid to strong alkali ranges.
It adopts manual temperature compensation. Users can adjust the compensator according to the actual liquid temperature to eliminate the temperature influence on electrode slope and guarantee accurate measurement results at different temperatures. Featuring simple operation, compact and lightweight design, it can be held with one hand, especially suitable for field sampling, workshop patrol inspection and mobile detection between different laboratories.
This portable pH tester is mainly used for the precise determination of solution acidity and electrode potential in laboratory and on-site environments. It serves as a reliable and practical basic tool for electrochemical analysis in many fields, including light industry manufacturing, chemical process control, pharmaceutical quality inspection, food safety production, health and epidemic prevention monitoring, environmental protection assessment, as well as scientific research and teaching in universities.
Application
1. Water Checks for Aquaculture
Regular pH screening of appropriate pond-water and source-water samples can be supported by a portable pH meter. Aquaculture operators can detect changes in water conditions and determine when more testing or remedial action may be required with the aid of routine checks. The species and operational conditions should be taken into consideration while determining the measurement criteria.
2. Water for Agriculture and Irrigation
As part of regular water management, pH screening can assist agricultural users in evaluating irrigation water and other appropriate water samples. Purchasers should verify that the accuracy and measurement range of the device match their intended use.
3. General Water-Quality Screening
When users need to evaluate several samples at several places, portable pH testers come in handy. As long as sample, calibration, and cleaning protocols are continuously followed, they can assist initial water-quality examinations.
4. Routine Industrial Checks
For initial testing of liquid samples, production and quality-control teams can use an appropriate portable pH tester. Verify whether the tester satisfies the necessary technical requirements before using it for applications demanding finer accuracy, controlled testing, or process-critical measurements.
5. Home and General-Purpose Testing
A portable pH tester might also be appropriate for simple tests of compatible household or general-purpose water samples, depending on the verified product requirements. Users should not assume that every model is suitable for drinking-water certification, food testin

FAQ
1. What is a portable pH tester used for?
A portable pH tester is used for pH measurement of suitable liquid samples. Depending on the model, it may support routine water-quality screening, aquaculture checks, agricultural water testing, and other basic testing tasks.
2. Is a portable pH tester suitable for aquaculture?
It may be suitable for routine pH checks of pond water and other compatible samples if the model's specifications meet the application's requirements. Buyers should verify measurement performance and operating conditions before use.
3. What is the difference between a pH tester and a portable pH meter?
The terms can overlap across product ranges. A compact tester is often selected for convenient routine checks, while some portable meters offer separate electrodes or additional functions. Compare actual specifications rather than relying on the product name alone.
4. How quickly can a portable pH tester provide a reading?
The response time depends on the selected model, electrode condition, sample properties, and measurement procedure. Refer to the official specification or operating manual for a confirmed response-time value.
5. Does the tester require calibration?
Calibration requirements depend on the model. Follow the manufacturer's procedure and use suitable standard buffer solutions. Do not assume that all testers have automatic calibration or buffer recognition.
6. Can I buy portable pH testers in bulk?
Contact Qiwei with the required quantity, destination market, and product requirements to request a wholesale quotation and confirm availability.
7. Can I request carton dimensions and packing details before ordering?
Yes. Ask the supplier to confirm the standard package contents, units per carton, carton dimensions, gross weight, and net weight for the actual product configuration.
8. Can Qiwei provide OEM or customized orders?
Qiwei accepts customized-order inquiries. Provide your expected quantity and requirements so the team can confirm the customization options available for the selected product.
9. Can I request product quality documents for a bulk order?
