Import Automatic Freezing Point Tester — Buy in wholesale FOB from Supplier in China

This Automatic Freezing Point Tester from Changsha Friend Experimental Analysis Instrument Co., Ltd is built specifically to GB/T510 for petroleum product freezing point determination, rather than the combined freezing-and-pour-point platform offered in the supplier's alternative model. The system manages two independent detection groups, each with automatic measurement and automatic result calculation via single-chip microcontroller control. Cooling spans +50°C down to -45°C using an imported compressor, with a 4mL minimum sample specification for trace-level work. Total electrical load is 800W on AC220V, 50Hz supply, matching standard Chinese laboratory infrastructure but requiring voltage verification for 110V regions.

The instrument's physical construction centres on a forced-air refrigeration train with overlay compressor architecture, a design choice that prioritises cooling speed and depth over thermoelectric alternatives. The LCD interface presents English prompts, while keyboard entry selects among multi-mode control programmes. USB communication to host computers is retained for networked laboratory environments. The two-group detection arrangement allows simultaneous processing of a test sample and a control or duplicate, though buyers should confirm whether the groups operate as mirrored channels or fully independent thermal zones with separate refrigeration circuits.

Target buyers include petroleum product quality laboratories, refinery in-process control departments, and customs or third-party inspection bodies verifying GB/T510 compliance for domestic distribution or export certification. The narrower scope, single-standard focus, and dual-group architecture suit facilities with high-throughput freezing point workflows rather than those needing pour point flexibility. Import considerations include confirming that the -45°C limit covers the lowest expected product specification (arctic diesel, for example, may require lower), and that the 4mL sample volume is compatible with available certified reference materials.

Changsha Friend Experimental Analysis Instrument Co., Ltd is located at 3f/8, No. 627 Lugu Road, Longsea Group, Changsha, Hunan, 410000, China. The supplier carries a Harbor trust tier designation, with platform-recorded response metrics showing 0.00 percent response rate and zero average response hours. This indicates verified registration status but no demonstrable engagement with platform-generated inquiries. Direct contact via the listed address or alternative channels is advisable for reliable communication.

The company's product range centres on petroleum analysis instrumentation, with this listing representing a single-standard variant in their cold-properties line. No manufacturing floor area, employee count, R&D investment figure, or client roster is available in the source profile. Certification claims for ISO 9001, ISO 14001, or specific industry body memberships are not present. Buyers evaluating this supplier against alternatives should request factory audit reports, reference installations, and evidence of sustained production capability for this specific model.
