Introduction of the Parr 7400 Automatic Isoperibol Calorimeter in India

Orbit Technologies Pvt. Ltd., in partnership with Parr Instrument Company (Moline, Illinois, USA), is pleased to announce the nationwide launch of the Parr 7400 Automatic Isoperibol Calorimeter across India. Engineered specifically for high-capacity testing laboratories, the 7400 sets a new benchmark in calorific testing speed, operator safety, and automated sample throughput.

The Parr 7400 introduces a fully automated vessel closure mechanism. Operators place the prepared sample crucible into the combustion head, and the instrument automatically lowers, seals, and fills the oxygen vessel to 30 bar. After combustion and measurement, the vessel is automatically depressurized and returned to the top opening without requiring physical lifting or manual bomb tightening by the technician.

With an optimized dynamic isoperibol temperature jacket and closed-loop thermoelectrically cooled water circuit, the Parr 7400 delivers complete test cycle times under four minutes per sample. This represents a dramatic 40% reduction in turnaround time compared to traditional isoperibol calorimeters, allowing commercial testing labs, coal washeries, and mega thermal power stations to analyze over 60 samples per 8-hour shift on a single instrument.

The system is fully compliant with all major international standard test methods including ASTM D5865, ASTM D4809, ASTM D240, ISO 1928, and Indian Standard IS 1350 (Part-II). Orbit Technologies provides complete turnkey installation, NABL-traceable benzoic acid calibration standards, comprehensive operator training, and annual maintenance contracts (AMC/CMC) supported by its 15 branch offices across India.
