Teledyne API Ultrafine Particle Monitor - Model 651 | Instrument Operation |
Status
Nozzle Pressure
Separator Temp
Cabinet Temp
Laser Current
Photodetector
Analog Input
Flow Constant
Description
The pressure difference upstream and downstream of the optics assembly. Should be 100% - a 10% drop in nozzle pressure indicates a nozzle clog.
Temperature of the Separator in degrees Celsius. A normal Separator temperature is 7°C.
Temperature inside the Model 651 cabinet. The operating current of the laser in mA. Indicates photodetector voltage in mV. Displays the voltage of the analog input.
Represented in particles/cm3. Compensates for any variations in orifice diameter.
