The Model 115 is an FID based Analyzer for measuring total hydrocarbons including methane to 50,000 ppm. It has enhanced features such as a faster response time, extended linear range and datalogging (see below).

The 115 includes the choice of one (1) Snap-On Module with FID, Operator's Manual, and Rechargeable Nickel Metal Hydride Battery.

Features

• Headspace Software - The accuracy of VOC measurements in soil and water is greatly improved with the built in software method. No operator interpolation is required.
• Single piece construction - The single piece construction (when the head and readout units are snapped together) of ABS plastic is very rugged and durable.
• Carrying case - For analyzer and disposable hydrogen cylinder.
• Ease of calibration - The two point calibration for the FID uses zero gas and a span gas. The time to calibrate is about 30 seconds. The Cal button is located on the main menu for ease of use.
• Datalogging - Manual or automatic datalogging (7,000 points) is available. The 115 has a built in real time clock. Viewer software (Windows 98-XP compatible) comes with the 115
• Library - There are libraries for the FID that are easily accessible. There are more than 200 response factors built into the 115
• Display - 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.
• ADC - 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
• Programmable Voltage output 0-1VDC
