Servers give off a lot of heat, and when cooling fails or can't keep up, a server room can overheat in minutes. The result can be shutdowns, failed hardware and lost data. Monitoring the room's temperature lets you catch a problem while there's still time to act.

Two kinds of monitoring

Logging with alerts. A data logger records the temperature continuously and warns you when it goes out of range. Our T&D TR71A2 connects over Wi-Fi and Bluetooth, uploads readings to the web, and can send alerts by email, so you'll know about a problem even when nobody is in the building.

A display you can see at a glance. A large wall display gives anyone walking past an instant read on the room. The BD923 large display thermometer can be read from more than 75 feet away, and it works as an independent backup if your logging or alert system ever fails.

Tips for setting it up

• Measure where the heat is. Place sensors near the server racks, especially at the equipment air intakes and any known hot spots, not just near the door or thermostat.
• Set alert limits that give you time to respond before the equipment reaches its own shutdown temperature.
• Use two independent systems. If the logger or network goes down, a standalone display still shows the temperature.
• Check calibration regularly. A sensor that reads low can hide a problem. We offer calibration and certification for the instruments we sell.
