We also accept customized orders.

 

 

 

The PHB-5 Portable acidity Meter is designed for easy pH measurement of solvent samples in laboratories, business workplaces, agrarian operations, aquaculture facilities, and environmental water testing. Its small handheld body and retractable E201-C hybrid electrode provide a useful solution for users who need to have the instrument between sampling locations.

Unlike a pen-type pH testing with an integrated detecting structure, this compact acidity meter connects to a distinct electrode through a BNC socket. This design allows the anode to become disconnected for examination, replacement, and routine maintenance, making it a practical option for organizations that need flexible picking equipment and available electrode replacement.

With a 0.00–14.00 acidity measuring range, ±0.1 pH precision, an LCD screen, and 9V battery power, the PHB-5 supports habit pH checks where simple operation and lightweight equipment are priorities.

For distributors, laboratories, water-quality service providers, and commercial buyers, Qiwei may discuss bulk buying and acceptable equipment configurations according to the intended software. Contact our team to verify electrode compatibility, validation requirements, and the suggested equipment package for your screening workflow.

 

product key technologies

01.

Introduction

PHB-5 Portable PH Meter, the instrument and electrode can be separated, connected with BNC socket. Therefore, the instrument is small in shape, electrode replacement is convenient, and the instrument reading is more reliable.

The instrument is suitable for research laboratory, industrial and mining production site, agriculture, fishery and animal husbandry, as well as the supervision of environmental protection and water quality, etc., and has a wide range of uses.

2. Power switch: ON/OFF

3. SLOPE adjuster: SLOPE

4. Positioning adjuster: AP

5. Electrode connection base: BNC

The PHB-5 Compact acidity Meter is suitable for routine acidity testing across a range of liquid-sampling processes. Its retractable electrode design is specially helpful when the device needs to be transported between picking points or when anode replacement is part of the maintenance plan.

1. Industrial Process and Quality Checks

Determine pH in qualified liquid samples collected from manufacturing and quality-control locations. Providers can use the meter for regular checks alongside their established picking and quality-assurance procedures.

2. Agricultural Water and Irrigation

Examine the pH of irrigation water and other appropriate agrarian water samples. Typical measurements can help users determine changes in water conditions and decide whether further analysis is needed.

3. Aquaculture and Fishery Operations

Determine the pH of fish-pond water, source water, and other appropriate samples during habit water-quality inspections. Results can help day-to-day tracking, while application-specific water-quality limitations may be determined according to the species and working conditions.

4. Environmental Water Sampling

Use the compact instrument for initial acid checks during field sampling and environmental water surveys. Where results are required for controlled reporting, users may follow the appropriate picking procedures, calibration requirements, and approved analytical methods.

5. Laboratory and On-Site Testing

Walk between sample areas without relying on a fixed tabletop setup. The retractable E201-C hybrid electrode can become disconnected for inspection or replacement when required.

1. Open the back cover and install the battery.

2. Connect the electrode to the BNC socket and turn on the power (press the switch)

3. Clean the electrode with pure water and wipe it dry, put the electrode in PH6.86 solution, stir it and put it stationary to stabilize the display value, and then adjust the positioning regulator (AP) with a small screwdriver to make the display value PH6.86 (25 ℃). Clean the electrode with pure water and wipe it dry, place the electrode in PH 4.00 (or PH9.18) solution, stir it and put it stationary to stabilize the display value, and then adjust the slope regulator (SLOPE) with a small screwdriver to make the display value PH4.00 (or PH9.18).

4. After the calibration is completed, clean the electrode with pure water and wipe it dry.

5. Put the electrode in the solution to be measured, stir it slightly, and then put it at rest to be displayed. The value is stable, that is, the PH value of the solution.

6. After the measurement, put the power switch OFF (release position), remove the electrode, and put on the protective cap.

1. After the instrument is calibration with a standard solution, it can be used continuously for one to two weeks, generally depending on the condition of the sample, the performance of the electrode and the number of times of use.

2. The instrument should avoid high humidity environment and corrosive gas, especially for BNC plug and socket.

3. If the displayed value becomes blurred or not displayed. Or when the display value error is large, the battery needs to be replaced.

4. After the standard solution is used up, the standard buffer can be prepared by itself; Take 250 ML distilled water or pure water from a volumetric bottle, pour it into a test cup to fully dissolve the reagent, and then put it into a glass bottle or a polyene bottle for airtight storage at low humidity (5-10℃).

1. What is the measurement selection of the PHB-5 Portable pH Meter?

The product pH range is 0.00–14.00, with an accuracy of ±0.1 pH.

2. Does the PHB-5 be used for industry water testing?

The lightweight design supports program pH checks of appropriate liquid samples at different sampling locations. Users may protect the instrument and electrode from inadequate climate conditions and follow the appropriate sampling procedures.

3. Does the PHB-5 have a retractable electrode?

Yes. The published design includes an E201-C hybrid electrode connected through a BNC outlet. This allows the sensor to become disconnected for examination and replacement, subject to compatibility requirements.

4. Does the PHB-5 provide automated temperature payment?

No. The published specs list no heat compensation. Users may consider sample temperature and the appropriate measurement procedure when understanding results.

5. Does the PHB-5 support automated buffer acknowledgement and data logging?

These features are not listed in the published PHB-5 requirements. The documented validation procedure uses guide AP and SLOPE adjustments. Customers who require automated validation, temperature payment, or electronic data storage should confirm the required functions with Qiwei before ordering.

6. Which validation filters should be used?

The published treatment describes validation with pH 6.86 followed by pH 4.00 or acid 9.18 cushion, depending on the intended measurement range. Observe the instrument's operating instructions and use appropriate standard solutions.

7. May I order substitute electrodes and accessories in bulk?

Call Qiwei with your required amount and the intended anode specifications. Confirm BNC cable compatibility and eligibility for the examples before placing an order.

8. Does Qiwei accept OEM/ODM and wholesale inquiries?

Qiwei accepts inexpensive volume orders and customized-order inquiries. Contact the team with your target number, brand needs, target market, and intended app to confirm available choices.
