MarCell PRO Cellular Power and Temperature Alarm with Probe

TheMarCell PRO cellular connected power failure and temperature alarm with probe provides monitoring for power failures, temperature/freeze and humidity. The external temperature probe is placed in a fridge or freezer or wherever the temperature needs to be monitored for high or low levels. The main unit plugs in to a nearby receptacle for power & monitoring.

The MarCell Pro doesn't require a connection to your network or any complicated set-up. It comes with a built-in pre-activated cellular communication to send data back to the cloud service for data logging and alerts.

Common Applications:

  • Refridgerator monitoring
  • Freezer monitoring
  • Temperature monitoring
  • Power monitoring

The cloud service will log temperatures every 30 minutes and upload them to the cloud service for later analysis. In case a power failure is detected or if the temperature goes above or below your set thresholds, an alert will immediately be sent by email and/or text to the contact(s) you specify.

The user can also request an immediate update at any time remotely. Up to 20 Real-time Data / Instant Updates per month are included with the PRO subscription.

The Marcell Pro service features advanced permissions and enterprise level views, allowing multiple units to be viewed in one account. Read-only access can be set up for specified users.

In case of a power failure, the on board rechargeable battery keeps it working for 24-48 hours so alerts can still be sent.

To provide further protection from costly water damage due to floods or leaky appliances, add an wireless water sensor part# SEN-100-WR

How often does Marcell report in with temperature and humidity data?

Current temperature and humidity is checked against your settings every 10 seconds. If the current readings are outside of your œsafe range�, an alert will be sent immediately. If readings are within your safe range, they are recorded every 30 minutes locally and uploaded every 8 hours to the cloud service for historical logging. At that point, this data is displayed on the web site in graph or chart form.

In case of an alarm condition, the alert is sent right away!
