Multi-Zone Fixed Point Refrigerant Leak Monitors
|
|
AGM300/ADM800
For continuous multi point monitoring of ammonia refrigerant gases
|
 |
HGM300/RDM800
For continuous multi point monitoring of CFC, HFC HCFC and halon refrigerant gases
|
These monitors enable up to 16 individual zones to be monitored continuously. Using split architecture design, advanced infrared technology and the latest in network communcation protocols, these monitors provide reliable point by point refrigerant loss monitoring at concentration levels as low as 1 ppm.
Innovations in Infrared Technology
- Select refrigerants to be measured - point by point!
- Eliminate false alarms with use of a non-dispersive IR source with sample draw system
- Measure all gases up to 10,000 ppm with a sensitivity of 1 ppm
- Sample points up to 500 feet from unit
Split Architecture Design
- Remotely acknowledge alarms provide maintenance and evaluate operating conditions
- Quick field expansion from 4 to 16 sampling zones with only a screwdriver
- Bolt in Bolt out internal components so the unit never leaves the wall
Enhanced Communication Protocols
- Full two way communication through RS-485 to the remote display module and building management systems such as Modbus RTU
- RS232C port for local/modem communication
Cost Effective
- Split architecture design keeps your investment to a minimum
- Two year warranty protects your investment
