Description
PRESSURE MEASUREMENT
| Absolute | Range: 0 to 950 mmHg Resolution: Within 0.05 mmHg Accuracy: Within 0.1% of full scale Linearity: < ± 0.1% of span |
| Relative | P/Po range: 0 to 1.0 P/Po Resolution: < 10-4 |
ANALYSIS
| Specific Surface Area | From 0.01 m²/g, nitrogen unit From 0.001 m²/g, krypton unit |
| Total Surface Area | From 0.1 m², nitrogen unit From 0.01 m², krypton unit |
| Pore Volume | From 4 × 10-6 cm³/g |
| Dewar Duration | Up to 40 hours |
ADSORPTIVE GASES
| Nitrogen Unit | Nitrogen; argon, carbon dioxide, or other non-corrosive gases; butane, methane, or other light hydrocarbon vapors; Oxygen can also be used only with an appropriate vacuum pump. |
| Krypton Unit | Same as Nitrogen unit, plus the capability to perform krypton surface area analyses at lower pressures |
| The TriStar should be operated in a properly vented environment when using flammable or toxic gases | |
MANIFOLD TEMPERATURE
| Nitrogen Unit | Must accommodate 20 × 10-3 mmHg or better; uses oil-based or oil-free vacuum pump |
| Krypton Unit | Must accommodate 01 × 10-3 mmHg; oil-free vacuum pump required |
