Limiting Oxygen Index (LOI) Tester

Limit Oksijen İndeksi (LOI) Cihazı

Minimum oxygen concentration to support combustion. Fully complying with fire safety regulations, it analyzes the flammability and burning behavior of materials with the highest precision. Equipped with superior safety features.

Model technical data

  • Through the touch screen controller and PC communication you can add different test methods.

Physical specifications and utilities

Electrical supplyApprox. 220–240 V AC, 50/60 Hz, single phase; build-dependent.
Power / connected loadApprox. 50–200 W connected load for preliminary planning.
Overall instrument dimensionsApprox. 600 × 500 × 700 mm (W × D × H).
Instrument weightApprox. 20–40 kg net.
Gross / shipping weightApprox. 32–60 kg gross; estimated packing allowance.
Lab requirementsOxygen and nitrogen cylinders of suitable purity, regulators and exhaust; pressure / flow depend on delivery configuration.

Dimension order and approximate values are stated in each row. Packaging data are separate from instrument dimensions and net mass. Approx. rows are preliminary engineering estimates based on comparable equipment and function/capacity; they are not verified manufacturing measurements or standard requirements. Installation and shipment are finalised against the approved drawing and nameplate. Estimate scope: base product / one unit; external computer, bench and auxiliary plant excluded.

Specifications, dimensions, and power requirements are approximate and subject to change without prior notice for continuous design improvements.

Product technical specifications and images may vary according to manufacturing conditions and applicable standards.

Test and configuration

Burner/gas flow, geometry and timing

Listed methods are application references. Suitability is established by assessing the selected hardware, current method and calibration together.

Test parameters for the reviewed method

Values belong to the stated source edition. Test recipe, fixture and delivered instrument configuration are selected together.

TS 11162-2 EN ISO 4589-2:2001 / EN ISO 4589-2:1999 · 5.1, 5.4

  • preferred chimney height at least 450 mm and diameter at least 95 mm; gas velocity 40 ± 10 mm/s at 23 ± 2 °C. Oxygen concentration measurement accuracy ±0.5% (V/V), adjustment precision ±0.1% (V/V). Kept separate from the ASTM recipe.

ASTM D2863-00 · 6.1, 6.4

  • Chimney bore 75-100 mm and height 450-500 mm; gas velocity 40 ± 2 mm/s at 23 ± 2 °C. Type A gas control uses ±0.5% concentration accuracy and ±0.1% adjustment precision; Type B is a separate accuracy class.

Control and recording specification

The following are method-specific software/recording requirements; delivered software modules are defined by the order scope.

  • Method code and edition, specimen ID, operator and selected test parameters are linked to the record.
  • The calculation and endpoint are defined by the selected method edition; instrument signals and operator assessments are kept distinct.
  • Raw measurements, units, valid/invalid test flags and the reported result remain traceable.
  • Calculations are checked against known inputs and an independent calculation; sensor channels are checked against calibration values.
