Description:
The Model Triathalon-C14 is a single-range ionization chamber C-14 (CO2) in air monitor housed in a NEMA-4X wall-mount enclosure designed for stack or room monitoring applications. This smart instrument includes a microprocessor, color LCD touch-screen display, and custom software with onboard data logging. The subtractive balanced chamber electrometer circuit and radon rejection decrease background to negligible levels. The software allows you to adjust units of measurement, alarm limits, the flow rate for totalizing, among other parameters. An upgraded alarm system provides two adjustable level alarms (alert level and high level), low flow alarm, and malfunction alarm (low voltage failure, high voltage failure, or electrometer failure).
An optional totalizer can be included which computes the total C-14 concentration released up the stack by multiplying the stack flow rate (manual or dynamic from stack flow sensor) by the measured C-14 concentration. The Triathalon-C14 is a cost-effective C-14 effluent monitor that is compact, lightweight, and includes an easy wall-mount configuration.

| LEVEL ALARMS | There are two C-14 Level Alarms, the indicator on the LCD is normally green and the message displayed is “C-14 Level OK” 1. C-14 Alert Level Alarm user-settable from 0.1 – 100 μCi/m3. Upon a C-14 Level Alarm the indicator on the LCD will turn yellow and display “High C-14 Level” 2. C-14 High Level Alarm user-settable from 1 – 1,000 μCi/m3. Upon a C-14 High Level Alarm, the indicator on the screen will turn red and display “HIGH C-14 LEVEL” |
| MALFUNCTION ALARMS | 1. Power Supply Fault:
Upon any failure of the low voltage power supplies, the indicator on the LCD will turn red and display “POWER SUPPLY FAULT LV”

Options
- Totalizer: Shows the total C-14 concentration released up the stack by multiplying stack flow rate by measured C-14 concentration. Stack flow rate is static and entered manually.
- Totalizer-RT: This totalizer uses real-time stack flow rate from customer’s existing flow sensor.
