LED Handle

The RGB LED handle lights on the ApexZ particle counter light up during and after sampling to indicate warning and alarm status. Flashing LED lights indicate that the ApexZ is currently taking a sample. If the LED light is a solid color, the instrument has stopped sampling. The color of the LED light after a sample is completed also shows the last recorded warning or alarm status.
