Model 114+ Portable LEL, CH4, CO, CO2 Analyzer

Click here to enlarge
  • The Model 114 is an IR based analyzer that utilizes interchangeable IR sensors (for CO2 and CH4) for low range or high range (0-100% v/v).
  • The Model 114 includes one IR sensor for CH4 or CO2 with up to 3 optional electrochemical sensors, datalogging, Operator's Manual, and Rechargeable Nickel Metal Hydride Battery. The main application is checking the composition of landfill gases.

Features

Sensors Ease of calibration Datalogging Display
One IR sensor and three electrochemical sensors. The two point calibration for each sensor uses a 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. Manual or automatic datalogging (7,000 points) is available. The 114 has a built in real time clock. Viewer software (Windows 98-XP compatible) comes with the 114. 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 Programmable Voltage output Optional sampling system available
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. View our PDF for more information.
