Snap on Heads Sensors Single piece construction Ease of calibration
Unique Snap on Heads are available only from PID. The readout unit recognizes the head type and calibration factors when the heads are interchanged. EC (approximately 30 optional EC sensors), TCD, or CG. The single piece construction (when the head and readout units are snapped together) of ABS plastic is very rugged and durable The two point calibration for the TCD uses a zero gas and a span gas. The time to calibrate is about 40 seconds. The Cal button is located on the main menu for ease of use.
Datalogging Library Display Backlit Display
Manual or automatic datalogging (7,000 points) is available. The 113 has a built in real time clock. Viewer software (Windows 98-XP compatible) comes with the 113. There are libraries for the TCD & CG built into the 113 Our 2 line by 16 character display can be backlit. The upper display provides the concentration and the bottom display provides the sensor, units, alarm and logging mode. Allows for easy visibility.
ADC Programmable Voltage output
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 0-1VDC
