Pressure: All Hawkeye borescopes we designed only for use at ambient pressure, however, we have several customers who have successfully used Hawkeye Borescopes at pressures up to 500 PSI and down to 10-6 Torr. As the scopes were not specifically designed for this, the operator does so at his own risk.
Chemical Resistance: All Hawkeye Pro Rigid borescopes (tube only, not the eyepiece end) are water tight and are resistant to most hydrocarbons; oils, gasoline, hydraulic fluid, jet fuel, etc. Exposure to Acids and strong Alkali should be avoided as it will attack the optical window.
