4. Main Product Features
Multi-standard Compatibility for Global Smoke Toxicity Certification
Fully meets GB/T20285 core requirements, compatible with DIN53436 and JIS A 1321 test protocols, test data recognized for domestic and international material smoke hazard grading reports.
Imported Long-Lasting Kanthal Heating Coil
Swedish Kanthal electric heating wire delivers stable uniform heating; service life 8 times longer than ordinary domestic heating elements, cutting frequent replacement maintenance cost.
Precision Stepper Motor Furnace Displacement Control
0.1mm speed accuracy with 5–50mm/min adjustable range, fast automatic reset after each test to shorten batch testing cycle and improve lab daily throughput.
Airtight Quartz Pipeline System with Zero Gas Leakage
All tube joints adopt precision grinding sealing technology; waste gas can be directly connected to workshop ventilation pipeline, no smoke spillage, eliminating need for extra laboratory fume hood.
10-Channel Synchronous Mouse Activity Real-Time Recording
High-sensitivity Hall sensors capture tiny rotation movements of each cage; PC displays 10 groups of activity curves simultaneously, auto archives data and prints complete toxicity test reports.
Large-Capacity Transparent Plexiglass Exposure Chamber
Clear organic glass chamber allows direct visual observation of mouse reaction; supports simultaneous exposure test for 10 test mice to improve data comparability of parallel samples.
All-In-One Intelligent Computer Operating Software
Independent 10 functional modules covering login, parameter setup, temperature monitoring, animal observation, data storage and report export; full-automatic one-click test operation with minimal manual intervention.
Complete Integrated Gas Mixing & Dilution Unit
Independent carrier gas and dilution air flow control valves, stable proportional flue gas dilution to create standardized toxic smoke concentration environment as specified in standards.
