Sensaphone 1800-CD Remote Monitor - Ultra-Low Temp Monitoring

Our review of the Sensaphone 1800-CD Remote Monitor finds it best suited for labs, medical freezers, and facilities that require reliable ultra-low temperature alerts. The single biggest reason to consider this unit is its ability to sense and issue alarms at temperatures down to -85 degrees Celsius, paired with a sealed enclosure and rechargeable battery backup that keep the monitor running through tough conditions. For operations that need multi-parameter monitoring and remote notifications, the 1800-CD delivers focused functionality without unnecessary extras.

Key Features

• Ultra-low temperature sensing: Detects and issues alarms as low as -85 degrees Celsius to protect sensitive samples and inventory.
• Multi-condition monitoring: Monitors up to eight environmental conditions so facilities can track temperature, tank levels, pressure and more from one unit.
• Alarm notifications: Sends alarm notifications to up to eight people so responsible staff are alerted quickly when conditions fall outside set limits.
• Durable sealed enclosure: The sealed enclosure provides added durability for use in cold or demanding environments where moisture or contaminants are present.
• Battery backup and voice messaging: Rechargeable battery backup maintains operation during power interruptions and recordable voice messaging gives clear alarm context.
• Remote control and phone use: Optional Bluetooth Adapter FGD-0230 enables integration with cell phones for remote access and control.

Who It's For

The Sensaphone 1800-CD is aimed at research labs, clinical storage, cryogenic facilities, and businesses that store vaccines, biologicals, or other temperature-sensitive materials requiring monitoring well below standard freezer ranges. It is especially useful where continuous alarm history, multi-contact notifications, and durable hardware are priorities.

Facilities that need a simple consumer-style monitor with app-first convenience or those with only occasional temperature needs may prefer a lighter, app-native solution. The 1800-CD is a professional device best suited for sites that require robust hardware, recordable voice alarms, and the ability to monitor several environmental inputs.
