Notable Features

MARALM003  Cellular Alarm is an advanced remote monitoring device that measures indoor temperature, relative humidity, and power status. Equipped with an external temperature probe, it is primarily used to monitor commercial refrigerators, coolers, and walk-in freezers. The external probe is 72″ (6 feet).

The setup is simple, with an intuitive interface that allows you and your team to set custom parameters for temperature and humidity ranges. If temperature or humidity exceeds the range you select or power is lost, you (and up to 9 people) will be immediately contacted by your preferred method of phone, text or e-mail.

MARALM003 Alarm detects water leaks with the addition of a SPuck water sensor. In an open field with a clear line of sight, there is solid communication between a SPuck and a MARALM003 of well over 320 feet.
