product key technologies

This microcomputer benchtop pH meter is engineered for laboratory analysis and industrial quality assurance work. It integrates pH and oxidation-reduction potential (ORP) measurement functions into one compact device, enabling users to capture these two key indicators that reflect the chemical state of liquid samples. This all-in-one structure streamlines daily testing work and removes the hassle of preparing multiple separate testers. A full set of standard accessories comes together with the meter, so users can start tests directly and do not need to buy basic spare parts individually.

Built to run physicochemical analysis for various liquid matrices, this instrument fits scenarios covering chemical production, drug manufacturing, food fabrication, sewage treatment and agronomic research. It delivers pH and ORP detection for water specimens, pharmaceutical liquids and liquid raw stocks. It is widely adopted for lab-scale trials, incoming material checks, in-line production surveillance and regular quality evaluation.

This instrument's flexible setup works well for controlled lab tests as well as regular on-site industrial detection. Users can rely on this single measuring platform to carry out sample assessment, process monitoring and quality verification throughout different production phases. Packing two testing functions into one unit, it brings a handy solution for facilities aiming to simplify liquid sample analysis and cut down equipment management workload.

The PHS-3CW microcomputer bench pH meter is developed to carry out regular pH and electrochemical tests for labs, research institutes and QC departments. Equipped with pH and mV testing capabilities, it accommodates diverse sample testing workflows for multiple sectors.

The PHS-3CW microcomputer bench pH meter is developed to carry out regular pH and electrochemical tests for labs, research institutes and QC departments. Equipped with pH and mV testing capabilities, it accommodates diverse sample testing workflows for multiple sectors.

1. Universities & Research Laboratories

pH testing serves as a basic experimental item for chemistry, biology and environmental studies in teaching labs and research centers. Its benchtop form suits conventional liquid analysis, potential reading and classroom lab demonstrations.

Common use cases:

Acid-base related experiments and reagent preparation

pH tracking throughout chemical reactions

Electrode potential detection with matched probes

Water sample testing for environmental studies

2. Food & Beverage Quality Control

pH acts as a key quality marker for most food and drink goods. Lab technicians can utilize this bench pH meter to check sample acidity for raw material incoming inspection, new product development and on-going quality monitoring.

Common use cases:

Acidity detection for drinks and fruit juices

pH testing of dairy items

Liquid sample analysis for food production

Quality verification of raw materials and end products

It is necessary to pick a proper electrode based on sample features and testing surroundings.

3. Pharmaceutical & Chemical Laboratories

pH measurement is frequently applied in reagent compounding, formula development and lab process validation. When fitted with a compatible probe, its mV function can also perform potential detection.

Common use cases:

Preparation of chemical reagents

General liquid sample analysis

pH testing for pharmaceutical formulations

Regular QC inspection of production intermediate samples

4. Environmental & Water Quality Testing Labs

This meter can perform pH detection on water specimens from different origins, such as surface water, sewage and lab-made test liquids.

Common use cases:

Potable water and process water testing

Waste water sample examination

Environmental monitoring trials

QC tests for water treatment labs

5. Agriculture & Soil Research

At agricultural testing facilities, pH readings assist researchers in examining soil extracts, nutrient mixes and irrigation water. When paired with a compatible electrode and standardized sample pre-treatment steps, this analyzer performs reliably for day-to-day sample testing.

1. Which parameters can the PHS-3CW microcomputer bench pH meter detect?

This unit supports three measurement modes: pH value, millivolt (electrode potential), and liquid temperature. Its measuring scope covers pH 0–14.00, ±1999 mV, and temperature from 0°C to 100°C. With a pH precision of 0.01 pH, it fits well for regular liquid analysis tasks inside laboratories.

2. What optional display resolutions are available for pH results?

Users of the PHS-3CW can switch between two pH display steps: 0.01 pH and 0.1 pH, to match different test scenarios. It is worth mentioning that resolution stands for the minimum visible change on screen, while accuracy reflects the deviation between measured data and the true value of the sample.

3. How to set up temperature compensation on this pH tester?

Temperature compensation is built into this meter as a basic measuring feature. If automatic temperature compensation (ATC) is needed, a separate 018 temperature probe is required. We suggest buyers check the sensor matching requirement and instrument configuration with us prior to placing orders.

4. What accessories are included in the standard package of PHS-3CW?

The standard packing set contains an E201-C composite pH electrode, pH calibration buffer reagents and a power adaptor. The 018 temperature electrode is sold separately as an extra part if ATC function is needed. Accessory lists may differ based on your configuration selection, so please double-check the final packing list before purchase.

5. Can the PHS-3CW be used for education and scientific research?

Absolutely. This pH meter is widely adopted for university teaching labs, pharmaceutical R&D centers, chemical analysis sections and other scientific testing sites. Its pH and mV measuring functions support regular sample tests, lab trials and sample assessment work.

6. Does QiweiLab offer bulk order terms for lab equipment distributors?

Yes. We accept enquiries from distributors, bulk wholesalers, universities and public institutions. Interested clients may ask for bulk pricing sheets, technical datasheets and custom accessory plans to meet their procurement assessment.
