Handheld PH Meter

Hangzhou Qiwei Instrument Co., Ltd. is one of the leading manufacturers and suppliers of handheld ph meter in China. With a professional production team, we are able to meet the needs of the majority of our customers. Welcome to wholesale bulk handheld ph meter in stock here from our factory. We also accept customized orders.

 

 

 

For regular field inspections, water quality checks, and commercial sampling workflows, the QiweiLab PHB-4 handheld pH meter is made. Instead of having to transport every trial to a fixed laboratory workstation, the instrument can be moved between sampling locations thanks to its handheld design.

A portable pH meter can perform routine checks at specific points in a process for water treatment teams, manufacturing plants, climate monitoring projects, and equipment distributors. The instrument's selection should be based on the desired acidity variety, ambient temperature, electrode configuration, calibration procedure, and working environment.

The PHB-4 has a published range of 0 to 14.00 vim, a range of mvc measurement range of 1999 mV, and a range of 0 to 60°C temperature measurement. The heat compensation range is 0 to 60 degrees Celsius. Before purchasing, check the model-specific datasheet to confirm the appropriate performance definitions and operating rules.

 

product key technologies

01.

This Handheld pH Meter, built with an electroanalytical transducer and featuring a space-saving configuration alongside easy carriage, serves to obtain real-time, rapid determinations of a solution's hydrogen ion concentration (i.e., its pH) within settings such as R&D facilities, assembly lines, and open country. Employed extensively across environmental conservation, water quality surveillance, academic instruction and scientific inquiry, pharmaceutical synthesis and chemical production, municipal water operations, consumable product sanitation verification, manufacturing process regulation, crop cultivation, and wilderness tasks, this device regularly adopts ergonomic shaping that permits one-palm usage, thereby withstanding severe industrial or open-air surroundings.

02.

The core technologies of handheld pH meters primarily revolve around their measurement principles, intelligent sensor management, human-machine interaction, and data management. Handheld pH meters typically employ electrochemical sensors (pH electrodes) for potentiometric measurement, determining the pH value of a solution by measuring the potential difference between the indicating electrode and the reference electrode. They are also equipped with automatic or manual temperature compensation to correct the effect of temperature on pH measurements. Moreover, to facilitate rapid in‑field handling, handheld pH meters typically feature an intuitive user interface and a low-power design to ensure long battery life.

Why Choose a Handheld pH Meter for Field Measurement?

 

Field dimension is different from regular testing at a preset laboratory bench. Providers may need to move between tanks, water inlets, manufacturing areas, storage vessels or outside picking points. A handheld device helps make these checks component of a useful inspection routine.

Common application scenarios include:

1. Business water inspection: Examine pH at selected water-sampling points during program process or maintenance inspections.

2. Wastewater picking: Determine collected examples as part of a water-treatment monitoring procedure.

3. Climate fieldwork: Compare acid readings between random locations and report results alongside sample identification and site conditions.

4. Agricultural and fishing water checks: Get spot measurements to support habit water-quality observation.

5. Manufacturing quality control: Test liquid samples during production or cleaning-process inspections where pH is a related control parameter.

6. Distributor and support applications: Supply a lightweight measurement option for customers who need industry checks rather than constant online monitoring.

For commercial use, evaluate the total dimension setup, including the sensor, electrode, connector, power supply and operating environment. An industrial software does not automatically mean that a handheld device is waterproof, ruggedized or appropriate for hazardous areas. Confirm the appropriate safety ratings and ecological limits before deploying the meter in demanding conditions.

 

1.The measuring electrode shall be rinsed with distilled water, taking care not to moisten the electrode connector during cleaning.

2.The connection interface between the electrode and the instrument must be kept highly clean and dry. If any contamination is present, it can be wiped clean with 99% alcohol.

QiweiLab accepts customized orders, but the availability of each customization option should be confirmed for the PHB-4 and the requested order quantity.

When requesting an OEM or private-label quotation, specify the requirements you would like to evaluate:

1. Branding: Logo printing, label design or branded packaging, subject to technical feasibility and order requirements.

2. Housing appearance: Preferred housing color or appearance, subject to available materials, tooling and minimum order conditions.

3. Language requirements: Required manual language and any requested interface-language changes, if supported by the instrument.

4. Accessories: Electrode model, spare electrode quantity, pH buffers, protective cover or carrying case, subject to compatibility and availability.

5. Packaging: Individual product packaging, carton labeling, barcode or destination-market requirements.

6. Documentation: Product datasheet, user manual and other available technical documents.

Please distinguish standard product supply from customization. Logo printing, housing color changes, software-language changes and custom packaging may have different feasibility, setup costs and minimum order quantities. Submit your target quantity and requirements so the supplier can confirm what is available before you finalize the purchase.

1. What is the pH range of the PHB-4 portable pH sensor?

The published acid dimension range is 0–14.00. This product website also lists an mvc range of ±1999 vim and a heat range of 0–60°C.

2. Is the PHB-4 ideal for commercial industry measurement?

It can be considered for regular pH inspections at business picking details. Confirm the working environment, safety rating, wire compatibility and required dimension performance before use in demanding technological conditions.

3. Does the PHB-4 include a protective sleeve or shock-resistant situation?

The listed basic settings includes an E201-C-W acidity temperature anode, pH solution and 4× AAA batteries. Confirm whether carrying case or another safety accessory is included or available individually.

4. May I customize the brand, housing color or software language?

Publish your requirements for review. Logo, shade, language and presentation options depend on design viability, order quantity and the supplier's confirmation.

5. How can I verify delivery day for an OEM order?

Offer the quantity, destination country, requested customization and accent list. Ask the provider to verify the production schedule and shipping estimate for the true order.
