Polarized LED Ring Light minimizes glare.
Suited for inspection microscopes, Model RL-9 comes with polarizing option that diminishes glare from reflective objects. It functions by allowing light from LEDs to pass through polarizing film before illuminating object. Light bounces off object and passes through analyzer before arriving at eye of operator or lens of camera. Rotating ring at center of ring light aligns analyzer with polarizer,...

Gas Regulator eliminates surge, lowers shielding gas use.
Designed for high-pressure/liquid cylinder or pipeline use, tamper-proof Gas-Saver regulator lets user remove key after appropriate flow rate is set to control process quality. Non-compensated flowmeter accurately displays gas flow rate, even when coupled regulator is adjusted to as low as 3 or 4 psi. This minimizes static pressure buildup in hose that would otherwise lead to surges, reducing...
