Customer Reviews

MarCELL Pro is an advanced remote monitoring device that measures indoor temperature, relative humidity and power status for commercial and industrial applications.

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 exceed the ranges 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.

MarCELL 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 MarCELL of well over 320 feet. Purchase the SPuck here
