FAQ
Q1: What testing scenarios is this tester mainly applied to?
A: The water content tester is used in food manufacturing, pharmaceutical quality control, chemical production, agricultural testing, cosmetics and research laboratories to measure the moisture or water content in solid, liquid and paste samples. It supports food product moisture determination for quality and shelf-life assessment, pharmaceutical water content testing per pharmacopoeial requirements, chemical raw material moisture verification, agricultural product moisture testing for storage and processing, and cosmetic formulation quality control. Water content is a critical parameter affecting product stability, texture, weight, shelf life and processing behavior. It is essential for food, pharmaceutical, chemical, agricultural and cosmetic industries requiring accurate moisture determination for product quality, regulatory compliance, process optimization, storage management and formulation control, where water content directly affects product stability, microbial growth, texture, chemical reactivity and consumer acceptance across multiple industries.
Q2: What standards does the tester comply with?
A: The water content tester supports methods referenced in ISO 1666 for starch moisture, AOAC methods for food, USP and EP for pharmaceuticals (Karl Fischer), ASTM methods, and relevant GB/T standards. The hardware complies with IEC 61010 laboratory safety standards. Calibration should use certified water standards or reference materials traceable to international standards.
Q3: What is the warranty period for the whole machine and key components?
A: The whole tester is covered by a 12-month warranty. The heating or titration system, balance, controller and sample chamber are covered, while sample pans, reagents and standards are consumables. Damage from improper sample loading 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 moisture analysis methods and sample handling. We provide operation manuals, training and application support. Proper sample preparation, method selection, calibration and result interpretation are important for accurate water content 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 water standards or reference materials recommended every 6-12 months. Balance calibration (for thermogravimetric) or burette calibration (for Karl Fischer) periodically. Daily performance verification with a control sample recommended for regulated laboratories. Reagent replacement per usage and expiration.
Q7: Are supporting consumables universal?
A: Sample pans, reagents, standards and desiccants are available from multiple qualified suppliers, though instrument-specific parts should be verified. Long-term consumable and reagent cost depends on testing volume and method type.
Q8: Can I customize parameters or supporting accessories?
A: Customization includes measurement method (thermogravimetric or Karl Fischer), sample capacity, detection limit and software features. Additional accessories and consumable kits can be ordered separately. Custom orders extend delivery lead-time.
Q9: Does the purchase include on-site installation and commissioning service?
A: Standard delivery includes the tester and accessories with an operation manual. On-site installation, commissioning and training are not included for standard orders but can be arranged for laboratory setup projects. Remote guidance is provided.
Q10: What types of samples are compatible with this equipment?
A: The tester measures water content in solids, liquids, pastes and powders within the method range and sample capacity. Volatile samples may lose non-water volatiles during thermogravimetric testing, requiring Karl Fischer method. Highly viscous or heterogeneous samples require proper homogenization. Users should select the appropriate method based on sample type and water content, follow proper sample preparation and homogenization, use certified calibration standards, ensure representative sampling, and report results with method specification for accurate, reproducible water content determination.
