Water Ratio Turbidimeter

Introduction

A water ratio turbidimeter is an instrument used to measure the turbidity of the water by the ratio method, which measures the light scattered and transmitted by the sample at the multiple angles, providing the improved accuracy, and it is used in the water treatment, the environmental monitoring, the laboratories, and the many other applications. The water ratio turbidimeter measures the turbidity by the measurement of the scattered and the transmitted light at the multiple angles, and it calculates the turbidity by the ratio of the signals, which reduces the interference from the color and the absorption of the sample, and it provides the turbidity value, expressed in nephelometric turbidity units (NTU), with features such as the calibration and the data logging; the water ratio turbidimeter consists of a meter, a light source, a sample cell, the multiple detectors, and the controls, and it is used for the measurement of the turbidity of the drinking water, the wastewater, and the environmental samples, for the quality control, for the monitoring, and for many other applications, and it is an essential instrument for the water analysis. Water ratio turbidimeters are used in the water treatment, in the environmental monitoring, in the laboratories, in the industry, and for many other applications. With their ratio measurement, water ratio turbidimeters are essential for the accurate turbidity measurement.

FAQ

Q1: What testing scenarios is this instrument mainly applied to?

A: The ratio turbidimeter is used in water treatment laboratories, environmental monitoring, industrial water testing and research institutions to measure turbidity in samples that may contain colored dissolved substances. The ratio technology compensates for light absorption by color, providing accurate turbidity readings for wastewater, industrial effluent, colored natural waters and other samples where standard nephelometric instruments would underestimate turbidity. It supports drinking water quality compliance, wastewater effluent monitoring, industrial process water control, environmental water quality assessment and research. It is particularly valuable for laboratories testing diverse water types where sample color variation could otherwise cause significant measurement errors and affect regulatory compliance reporting.

Q2: What standards does the instrument comply with?

A: The meter complies with ISO 7027 for water quality turbidity, EPA Method 180.1, ASTM D7315 and relevant GB/T 13200 and HJ standards. Ratio measurement follows the ratio nephelometric method specified in applicable standards. The instrument complies with IEC 61010 laboratory safety standards. Calibration should use certified formazin or AMCO-AEPA standards.

Q3: What is the warranty period for the whole machine and key components?

A: The whole meter is covered by a 12-month warranty. The optical system, detectors and controller are covered, while sample vials and calibration standards are consumables excluded from warranty. Optical window damage from scratches or improper cleaning is also excluded.

Q4: Is this device difficult to operate? Is professional training required?

A: Operation requires basic training in calibration and turbidity measurement. We provide an operation manual and remote guidance. Proper vial handling, sample preparation and calibration procedures are important for accurate results. The ratio compensation operates automatically once calibrated.

Q5: What is the typical lead-time for order delivery?

A: Standard models require 7-30 working days. In-stock units can ship within 3-7 working days. Custom configurations or large built-to-order systems may require additional time, and we confirm the exact schedule before order confirmation.

Q6: Is regular calibration required? What is the recommended calibration cycle?

A: Calibration with certified turbidity standards should be performed before each use session for critical measurements. Full meter calibration is recommended every 6-12 months. Sample vials should be inspected and replaced when scratched. Optical window cleaning should follow the manufacturer schedule.

Q7: Are supporting consumables universal?

A: Calibration standards and sample vials are available from multiple suppliers, though certified standards and matched vials are recommended. Long-term consumable cost is low, with vial replacement being the main recurring item.

Q8: Can I customize parameters or supporting accessories?

A: Customization includes measurement range, optical configuration and data output. Additional vials, standards and accessories can be ordered separately. Custom orders extend delivery lead-time.

Q9: Does the purchase include on-site installation and commissioning service?

A: No complex installation is required beyond power connection. The package includes the meter, vials, standards and instruction manual. On-site calibration service is available at additional cost.

Q10: What types of samples are compatible with this equipment?

A: The ratio turbidimeter measures turbidity of water and aqueous solutions including colored samples within the measurement range. Very high turbidity samples may require dilution. Extremely dark or opaque samples may exceed the compensation capability. Users should handle sample vials carefully to avoid scratches and bubbles, follow proper calibration procedures, and verify that the ratio compensation is appropriate for the sample color intensity to ensure accurate and reliable turbidity results.
