Model A-21Z portable ozone sensor provides a reliable and inexpensive way od checking generators, valves, piping and general environments for ozone leaks and for estimating ozone levels. It can be used as a permanent monitor indoors when concentrations average below .1 ppm. It may be used outdoors and for a concentrations up to 10 ppm for short periods of time. The A-21Z features:

• Small size and high sensitivity due to HMOS (heated metal oxide semiconductor) sensor.
• Sensitivity: as low as 0.02 ppm. Range: 0-10 ppm.
• Size: 2" x 4" x 1" (50 x 100 x 25 mm).
• Weight: 6 ounces (170 grams).
• Warms up in minutes. Responds in seconds.
• Ease of calibration and service.
• Basic power requirement is 12 volts DC unregulated. Works from AC adapter available worldwide.
• Tubing inlet adapter (Also useful for pinpointing leaks).
• Digital readout in 0.01 ppm increments.
• Rechargeable batteries last more than 2 hours.
• Very simple operation.
