| Technology Just as mobile phones and industrial computers have become smaller, smarter and more affordable, BW has brought the same technological advances to gas detection instrumentation. Cutting-edge technology in sensors, microprocessors, programming features and fiber optics result in a more compact and easier to use safety instrument—at a lower cost. Full Function Self-Test BW Technologies' unique, full function self-test automatically checks battery, circuitry and sensor integrity. Our instruments are engineered with self- diagnostic capabilities that verify each sensor's response to gas. Automatic Calibration During auto-cal and auto-span procedures, BW instruments advise when to apply gas—no setting adjustments are required. The instrument also checks that the concentration (ppm or %) meets expected criteria. GasAlertClip, GasAlert100, Toxyclip and Toxyclip2 do not require calibration. |
