GR Series
GR Series Overview Semi-micro, 0.01 mg readability up to 42 g (GR-202) Handy lever on the front to open either side of the weighing chamber for quick and efficient access Small footprint of 249 mm by…
Engineered for rigorous testing environments across coal, fuels, minerals, and advanced materials. Delivers automated determination, high operational reproducibility, and seamless compliance with international ASTM and ISO laboratory standards.
Instrument Overview & Operating Principle
GR Series Overview Semi-micro, 0.01 mg readability up to 42 g (GR-202) Handy lever on the front to open either side of the weighing chamber for quick and efficient access Small footprint of 249 mm by 330 mm to save space Adjustable (manual or automatic) response characteristics to help cope with the effect of drafts
Scientific Architecture & Measurement Physics
1. Precise Thermal Equilibration
The jacket enclosure is thermally regulated to eliminate ambient room temperature variations. High-resolution thermistors capture micro-degree changes across the sample combustion cycle with instantaneous data acquisition.
2. Certified Combustion Vessel Integrity
Constructed from proprietary high-strength corrosion-resistant alloys capable of withstanding working pressures up to 300 bar. Automated firing protocols ensure complete oxidation without sample splattering.
3. Microprocessor Algorithmic Correction
Real-time numerical integration compensates for fuse ignition heat, acid formation, and thermal leakage, calculating Gross Calorific Value (GCV) strictly compliant with ASTM D5865 and ISO 1928 formulas.
4. Automated Workflow & Vessel Handling
Automated oxygen filling and water bucket management reduce operator hands-on time from 15 minutes down to under 1 minute per test, minimizing human error and maximizing laboratory throughput.
