FAQ
Q1: What testing scenarios is this refractometer mainly applied to?
A: The refractometer is used in food and beverage production, pharmaceutical manufacturing, chemical processing, gemology, automotive maintenance and agricultural testing to measure the refractive index of liquids and solids for concentration determination and quality assessment. It supports sugar content measurement in fruit juices, wines and honey, coolant and battery fluid testing in automotive maintenance, pharmaceutical solution concentration verification, chemical product quality control, gemstone identification and salinity measurement. The refractive index provides a rapid, non-destructive indicator of solution concentration or material identity. It is essential for food and beverage quality control, pharmaceutical manufacturing, chemical processing, automotive service and gemological laboratories requiring fast, reliable refractive index measurement for product quality, concentration determination, material identification and regulatory compliance across multiple industries where refractive index correlates with composition, purity or concentration.
Q2: What standards does the refractometer comply with?
A: The refractometer supports methods referenced in ISO 1743 for glucose syrup, ICUMSA methods for sugar, ASTM standards for specific applications, and relevant GB/T standards. The instrument complies with relevant safety standards. Calibration should use certified refractive index standards or distilled water for routine verification.
Q3: What is the warranty period for the whole machine and key components?
A: The whole refractometer is covered by a 12-month warranty. The optical system and body are covered, while calibration tools and batteries (digital) are accessories. Damage from improper cleaning, dropping or unauthorized repair is excluded.
Q4: Is this device difficult to operate? Is professional training required?
A: Operation is simple: place a few drops of sample on the prism and read the scale or digital display. No professional training is required, but users should follow proper sample application, temperature compensation and calibration procedures. We provide an operation manual and remote guidance.
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 distilled water or certified refractive index standard should be performed periodically, typically before each use session for critical measurements. Prism condition and cleanliness verified regularly. Full optical calibration recommended annually for precision instruments.
Q7: Are supporting consumables universal?
A: Calibration standards and pipettes are available from laboratory suppliers. Long-term consumable cost is very low for a refractometer.
Q8: Can I customize parameters or supporting accessories?
A: Customization includes measurement scale (Brix, salinity, coolant, etc.), precision level, automatic temperature compensation and digital features. Additional 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 refractometer, calibration tool and instruction manual. On-site service is not included for this type of portable instrument.
Q10: What types of samples are compatible with this equipment?
A: The refractometer measures refractive index of transparent liquids and some solids within the measurement range. Opaque or highly colored samples may not be suitable for some models. Very viscous samples require proper spreading on the prism. Corrosive samples may damage the prism and require special handling. Users should ensure the prism is clean and dry before each measurement, apply sufficient sample to cover the prism, allow temperature equilibration for accurate results, and clean the prism thoroughly after each use to prevent residue buildup and maintain measurement accuracy.
