Constant temperature needle penetration tester

Introduction

A constant temperature needle penetration tester is an instrument used to measure the penetration of needles or probes into materials, such as petroleum products, waxes, greases, and food products, at a controlled temperature, and it is used in the petroleum, food, cosmetic, and materials industries for quality control and specification testing. The most common application is the penetration test for bitumen and asphalt, in which a standard needle is allowed to penetrate a sample at a specified temperature, typically 25 degrees Celsius, under a specified load and time, and the penetration depth is measured in tenths of a millimeter, indicating the consistency and hardness of the material; the instrument maintains the sample at the constant test temperature with a temperature-controlled bath, and it precisely controls the release of the needle and measures the penetration depth, and it is used with standard methods, such as ASTM D5 for bitumen penetration. Constant temperature needle penetration testers are used for testing bitumen and asphalt for road construction, for testing waxes, for testing greases and lubricants, for testing petroleum jellies, for testing food products, such as cheese and gelatin, for testing cosmetics, such as lipsticks, and for other materials whose consistency is evaluated by penetration, and they are available in various configurations, including manual and automatic models, with features such as precise temperature control, automated needle release, and digital measurement. With their precision, constant temperature needle penetration testers are essential for consistency testing in many industries.

FAQ

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

A: The constant temperature needle penetration tester is used in bitumen and asphalt testing, petroleum laboratories, road construction, wax and grease manufacturing, quality control and research to measure the needle penetration of bitumen, asphalt, waxes, greases and other semisolid materials at a controlled temperature for consistency assessment, product grading and quality control. It supports bitumen and asphalt penetration grading for road construction, petroleum product consistency testing, wax and grease hardness measurement, lubricating grease penetration testing, and quality control of semisolid materials. The controlled temperature ensures consistent, reproducible penetration measurements, as penetration is highly temperature-dependent for these materials. It is essential for bitumen, asphalt, petroleum, wax, grease and quality control laboratories requiring needle penetration measurement at controlled temperature for material grading, consistency assessment, quality control and specification compliance, where the precision needle and constant temperature bath provide accurate, reproducible penetration measurements for bitumen grading, petroleum product testing, wax and grease characterization and quality assurance in road construction, petroleum and industrial applications requiring standardized penetration testing per ASTM, ISO and industry specifications.

Q2: What standards does the tester comply with?

A: The needle penetration tester follows ASTM D5 for bitumen penetration, ASTM D217 for grease cone penetration, ISO 6598 for bitumen, and relevant GB/T standards including GB/T 4509 for bitumen penetration and GB/T 269 for grease. The needle dimensions and mass follow the standard specification. Temperature control should be verified with a calibrated thermometer. The apparatus complies with relevant laboratory safety standards.

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

A: The whole penetration tester is covered by a 12-month warranty. The needle mechanism, temperature bath, timer, controller and housing are covered, while needles, sample cups and fuses are consumables or accessories. Damage from improper use, needle damage or unauthorized repair is excluded. Extended service contracts may be available.

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

A: Operation requires trained laboratory personnel familiar with penetration test methods and temperature control. We provide operation manuals, training and application support. Proper sample preparation, needle selection, temperature equilibration, timing and result reading are important for accurate penetration 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: Needle mass and dimension verification recommended every 6-12 months. Temperature bath calibration against a reference thermometer periodically. Timer accuracy verified. Needle condition (sharpness, straightness) checked before each use. Full apparatus verification for accredited laboratories. Routine cleaning after each use.

Q7: Are supporting consumables universal?

A: Penetration needles, sample cups and thermometers are available from laboratory suppliers, though dimensions should match the standard method. Long-term consumable cost is low.

Q8: Can I customize parameters or supporting accessories?

A: Customization includes needle type (standard bitumen, cone for grease), temperature range, sample capacity, automation level and accessories. Additional needles, cups and accessories 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 penetration tester and accessories with an operation manual. On-site installation, calibration and training are not included for standard orders but can be arranged for quality control laboratory setup. Remote guidance is provided.

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

A: The needle penetration tester measures penetration of bitumen, asphalt, waxes, greases and other semisolid materials within the penetration range, temperature and needle specification. Different materials require specific needles (standard needle for bitumen, cone for grease) and test temperatures (typically 25 degrees C for bitumen). Samples should be properly prepared, poured and conditioned per the standard method. Users should follow the specific test method for the material, use the correct needle and mass, control temperature precisely, allow proper sample conditioning and temperature equilibration, perform the test within the specified time, report results in tenths of a millimeter (0.1mm) with temperature specified, and maintain proper needle sharpness and straightness. The sample should be free of bubbles and properly leveled. For bitumen grading, penetration at 25 degrees C is used to classify bitumen grades (e.g., 60/70, 80/100). The test should be performed in a draft-free area, and multiple determinations should be made for representative results. The needle should be cleaned between tests to prevent cross-contamination.
