FAQ
Q1: What testing scenarios is this meter mainly applied to?
A: The benchtop density meter is used in pharmaceutical quality control, chemical analysis, food and beverage testing, petroleum refining, beverage production and research laboratories to precisely measure the density of liquid samples using the oscillating U-tube method. It supports pharmaceutical solution concentration and specification testing, chemical product purity and quality verification, beverage alcohol content and sugar concentration determination, petroleum product density and API gravity measurement, food product quality assessment, and concentration determination of solutions. The oscillating U-tube provides fast, accurate density measurement with small sample volume, suitable for high-throughput quality control. It is essential for pharmaceutical, chemical, food, beverage, petroleum and research laboratories requiring precise liquid density measurement for product quality, concentration determination, purity assessment, regulatory compliance and process control, where density is a fundamental physical property used to calculate concentration, verify product specifications, assess purity and monitor processes across multiple industries.
Q2: What standards does the meter comply with?
A: The density meter supports methods referenced in ISO 12185 for crude petroleum, ASTM D4052 for petroleum products, ASTM D5002 for crude oils, pharmacopoeial methods, OIML R123 for density meters, and relevant GB/T standards. The hardware complies with IEC 61010 laboratory safety standards. Calibration should use certified density reference standards traceable to international standards.
Q3: What is the warranty period for the whole machine and key components?
A: The whole density meter is covered by a 12-month warranty. The measuring cell, temperature control, pump and controller are covered, while tubing, syringes and standards are consumables. Damage from improper sample introduction, corrosive samples or unauthorized repair is excluded. Extended service contracts are available.
Q4: Is this device difficult to operate? Is professional training required?
A: Operation requires trained analysts familiar with density measurement and sample handling. We provide structured training, operation manuals and application support. Proper sample introduction, bubble removal, cell cleaning and calibration are important for accurate density 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: Calibration with certified density standards (air and water or certified standards) recommended before each analytical batch and fully recalibrated periodically. Measuring cell cleaning after each sample series. Temperature calibration every 6-12 months. Daily performance verification with a control sample recommended for regulated laboratories.
Q7: Are supporting consumables universal?
A: Syringes, tubing, filters and calibration standards are available from the manufacturer or authorized distributors, though original consumables are recommended for performance. Long-term consumable cost is moderate depending on sample volume.
Q8: Can I customize parameters or supporting accessories?
A: Customization includes measurement range, accuracy level, sample introduction type, temperature range and software features. Additional kits and accessories can be ordered separately. Custom orders extend delivery lead-time.
Q9: Does the purchase include on-site installation and commissioning service?
A: Yes, benchtop density meters include on-site installation, commissioning, calibration and operator training by certified application specialists. Site preparation guidance is provided before delivery to ensure power and environmental requirements are met.
Q10: What types of samples are compatible with this equipment?
A: The density meter measures density of homogeneous liquids within the measurement range, temperature specification and viscosity limit. Highly viscous samples may require special handling or syringe injection. Corrosive samples may require special measuring cell material. Samples with suspended particles can abrade the U-tube and require filtration. Users should ensure samples are bubble-free, properly degassed if necessary, use certified calibration standards, clean the measuring cell thoroughly between samples to prevent cross-contamination, and verify cell cleanliness and dryness before calibration for accurate, reproducible density measurement.
