Battery Testers

The STC 704 is a wireless environmental monitoring system that provides off-site monitoring of four parameters. Plus it gives alerts for A.C. power loss, daily communication tests, low battery, and “restore to normal” conditions. Our model operates on 5G using the latest in cellular modem technology, meaning you get a fast, accurate signal—faster than any other products like it! Also included with the STC 704 are two web-controllable relays, so you can interface to on-site equipment where a 5-amp dry contact can be used. The unit comes complete with standby battery, power transformer, 5 conductor wire for connections, and a detailed installation manual.
