|The single piece construction NEMA 4 enclosure constructed of fiberglass is waterproof, very rugged and durable./td>||The two point calibration for the PID uses an electronic zero (no zero gas needed) and a span gas. The time to calibrate is about 10 seconds. The Cal button is located on the main menu for ease of use. The FID requires zero air and span gas for calibration.||Our 2 line by 16 character display is backlit. The upper display provides the concentration and the bottom display provides the sensor, units, alarm and logging mode. For multisensor units, a 3 readout LED is used.||Our 16 bit ADC provides a resolution of 1 part in 64,000 and our signal algorithm minimizes noise by signal averaging in the msec range.|
