QiweiLab's compact dissolved gas meter is designed for users who need to determine dissolved oxygen in water samples outside a set laboratory workstation. With a listed DO assessment range of 0.00–20.00 mg/L and a temperature measurement variety of 0–40°C, the device can be considered for regular water excellent checks, environmental sampling and field-based lab work.

Portable Would testing allows technicians to determine samples close to the selection point, reducing the need to transfer every sample back to a central laboratory for an original measurement. It can help industry surveys, water treatment checks, fishing inspections and research activities where dissolved air is one of the parameters being evaluated.

The current published specs list a dissolved oxygen fundamental mistake of ±0.3 mg/L and a temperature fundamental error of ±1°C. Before purchasing, users should also check the screen resolution, validation process, suitable DO electrode, heat compensation method, power supply and included accessories against the latest model-specific datasheet.

For liquid testing contractors, lab equipment distributors, environmental monitoring teams and organisational buyers, QiweiLab provides a touch point for technical specification inquiries and half quotations. If your job requires outside protection, a carrying case, extended power operation or a certain anode technology, include those requirements in your investigation so that the available construction can be confirmed before ordering.

 

product key technologies

The intelligent dissolved oxygen controller is mainly designed for the convenience of users to carry it to the field for operation. The instrument can be divided into two parts: sensor and electronic unit. The sensor adopts polarographic coated dissolved oxygen electrode. The electronic unit is composed of highly integrated circuits. The instrument adopts a dot-matrix LCD display, which can show dissolved oxygen and temperature values.

1. LCD display;

2. Automatic temperature compensation, fast response time;

3. Portable, easy to carry;

4. High-precision digital display with high accuracy;

5. Equipped with our dissolved oxygen electrode (polarographic film-covered type).

Credible field measurements depend on accurate anode preparation, calibration and sample handling. Before starting a dimension campaign, inspect the Would electrode and its cable, examine the sensing components according to the anode guide, and make sure the instrument is configured for the right sensor.

A useful field process includes the following steps:

1. Prepare the instrument.

Check the power condition, electrode link and device settings before travelling to the sampling location.

2. Prepare and examine the electrode.

Follow the manufacturer's directions for electrode planning. For an electrolytic electrode, check the membrane and liquid condition where appropriate. For an optical detector, follow the specified washing and calibration process.

3. Calibrate the instrument.

Carry out the calibrate process described in the customer manual. The required calibration stage, reference condition and stability time rely on the detector design and instrument configuration.

4. Measure the sample.

Rinse or make the electrode as instructed, spot it in the test using the specified measurement arrangement, and let the reading to maintain before recording the result.

5. Clean and store the electrode.

After testing, clear the detector according to its material and application. Use the specified storeroom method and avoid damaging the layer, optical sensing surface or electric connection.

6. Review effects and repair needs.

If readings are fragile or contradictory, check the validation, sensor condition, heat, test handling and cable connection before repeating the measurement.

If your industry process requires one-key validation, confirm the specific operation sequence and supported calibration mode for the selected meter. Request the existing users manual from QiweiLab before establishing a standard operating procedure for your group.

1. What is the dimension range of the compact DO meter?

QiweiLab lists a dissolved gas assessment range of 0.00–20.00 mg/L and a temperature assessment selection of 0–40°C. Satisfy refer to the current product sheet for the entire requirements.

2. What is the difference between optical and electrolytic Would dimension?

Optical cameras measure dissolved air through an optical response, while electrolytic sensors use an electrolytic sensing process. Their maintenance requirements and appropriate accessories properly differ. Confirm the sensor technologies supported by the selected sensor before purchasing.

3. Is the compact Would meter durable to IP67?

The Internet safety score must be confirmed for the exact device and electrode configuration. Please request the appropriate datasheet or check documentation before using the instrument in damp environments.

4. Does the device aid one-key validation?

The specific calibration work and working procedure should be confirmed from the model-specific consumer manual. Call QiweiLab if your industry workflow requires a specific calibration method.

5. Are a carrying case and chargers included?

The standard package material should become confirmed in the statement or packing list. Please identify whether you need a carrying case, replacement chargers or other industry accessories.

6. Which Would electrode and consumables may I purchase?

Compatibility depends on the device type and sensor technology. Offer your meter model and electrode requirements so that QiweiLab you confirm the proper electrode and any relevant maintenance components.

7. May I request a test or field test kit?

Contact QiweiLab with your program, required amount and place country to confirm whether a sample product or industry test kit is obtainable and what the package includes.

8. You I buy compact DO meters in bulk?

Well, you can post a mass inquiry with your target quantity, destination market and supplement requirements. MOQ, costs, warranty terms and shipping lead time should be confirmed in the written statement.
