The 1800 monitoring system from Sensaphone provides cost-effective 24/7 remote monitoring of environmental conditions at unattended water treatment operations. It detects problems such as temperature changes (from minus 109 to 168 degrees Fahrenheit), humidity fluctuations, water leaks, power failure, carbon monoxide and carbon dioxide levels, and smoke. When the system identifies a potential issue, it can immediately alert up to eight people with custom phone calls, allowing personnel to quickly address the situation. The internal rechargeable battery backup provides 24 hours of continuous monitoring and alerts in the event of a power outage. Operators can obtain the status of each monitored condition at the installation site or remotely by telephone. 877/373-2700; www.sensaphone.com.
