Urometer

Introduction

A urometer, also known as a urinometer or urine specific gravity meter, is an instrument used to measure the specific gravity of urine, which indicates the concentration of dissolved substances in the urine and reflects the ability of the kidneys to concentrate the urine, and it is used in clinical laboratories and medical settings. The urometer measures the specific gravity of the urine sample by various methods, including the hydrometer method, in which a calibrated float, the urinometer, is placed in the urine, and the depth to which it sinks indicates the specific gravity, read on the scale; the refractometer method, in which the refractive index of the urine, which is related to the concentration of dissolved substances, is measured and converted to the specific gravity; and the reagent strip method, which estimates the specific gravity colorimetrically, and the specific gravity of normal urine ranges from about 1.001 to 1.035, with higher values indicating more concentrated urine and lower values indicating more dilute urine. Urometers are used in clinical laboratories and medical settings as part of the routine urinalysis, for assessing the concentration of the urine, for evaluating kidney function, for monitoring hydration, for diagnosing and monitoring conditions that affect the concentration of the urine, and for research, and they are available as simple hydrometers, handheld refractometers, and electronic meters, with features such as digital displays and automatic temperature compensation. With their measurement of urine concentration, urometers are essential instruments for urinalysis in clinical settings.

FAQ

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

A: The urometer is used in clinical laboratories, hospitals, nephrology departments, urology clinics, healthcare facilities and research to measure urine volume and specific gravity for renal function assessment, hydration status evaluation and clinical diagnosis. It supports clinical urine analysis (routine urinalysis volume and specific gravity), renal function monitoring (glomerular filtration, concentrating ability), hydration status assessment, 24-hour urine collection measurement, nephrology patient monitoring, urology diagnostic testing, and general clinical laboratory urine testing. The combined volume and specific gravity measurement provides essential clinical information about kidney function and fluid balance, widely used in clinical diagnostics and patient monitoring.

Q2: What standards does the urometer comply with?

A: The urometer follows relevant ISO, ASTM and GB/T standards for clinical urine testing, including ISO 18745 for urine specific gravity, relevant clinical laboratory standards, and applicable medical device regulations (FDA, CE, NMPA). The hardware complies with applicable safety standards. Calibration should use certified reference solutions for specific gravity. Clinical use follows applicable laboratory accreditation requirements (ISO 15189, CAP, CLIA).

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

A: The whole urometer is covered by a 12-month warranty. The graduated cylinder, hydrometer, thermometer and housing are covered, while replacement parts and accessories are consumables. Damage from improper use, breakage (glass) or unauthorized repair is excluded. Extended warranty may be available.

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

A: Operation requires trained clinical laboratory personnel familiar with urine testing and proper measurement technique. We provide operation manuals, training and application support. Proper sample collection, volume reading (meniscus), hydrometer technique, temperature correction, quality control and result interpretation are important for accurate clinical results.

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: Hydrometer calibration with certified reference solutions recommended every 6-12 months. Volume graduation verification periodically. Thermometer calibration against a reference. Routine inspection for damage (glass breakage, hydrometer integrity). Full urometer performance verification annually for clinical use.

Q7: Are supporting consumables universal?

A: Replacement hydrometers, cylinders, thermometers and cleaning supplies are available from clinical laboratory suppliers, though compatibility should be verified. Long-term consumable cost is low.

Q8: Can I customize parameters or supporting accessories?

A: Customization includes cylinder volume, hydrometer range, material (glass, plastic), temperature compensation, scale type and accessories. Additional replacement parts 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 installation is required. The package includes the urometer and instruction manual. On-site training is available at additional cost for clinical laboratory setup.

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

A: The urometer measures volume and specific gravity of urine samples within the cylinder volume and hydrometer range specification. Urine samples should be properly collected (clean catch, catheter, 24-hour collection) and at room temperature for accurate specific gravity measurement (temperature correction required if not at calibration temperature). Very dilute or concentrated urine may exceed the hydrometer range. Users should follow proper urine collection procedures, read volume at the meniscus (eye level), use proper hydrometer technique (float freely, no bubbles, read at meniscus), apply temperature correction if needed, include quality control samples, report results with proper units (volume in mL, specific gravity as dimensionless), and for clinical use, follow applicable standard methods and laboratory accreditation requirements. The urometer should be cleaned thoroughly between samples to prevent cross-contamination (use detergent, rinse, dry). Glass components should be handled carefully to prevent breakage. For 24-hour urine collections, ensure proper collection container and preservation (if required for other analytes). The hydrometer should be inspected for cracks or damage before use. Specific gravity can also be measured by refractometer or reagent strip as alternatives, but the urometer hydrometer provides a direct measurement. For patients with renal disease, specific gravity is an important indicator of renal concentrating ability. The urometer should be stored properly (clean, dry, protected from breakage). For clinical use, maintain proper quality control and documentation per laboratory regulations.
