| Replaceable OS-4 Sensor Chip |
Product ID: OS-4 |
The OS-4 uses the SM-X sensor chip to monitor ozone. When calibration is necessary this chip can simply be replaced with a pre-calibrated new unit. The SM-X chip will cost $110, this is only $10 more than the standard recalibration cost, and you get to keep the monitor in operation the entire time! The SM-X will help make the OS-4 the lowest cost sensor for long time operation you can buy. Image is actual size |
