X-300 Advanced Temperature



The X-300™ is two very different products in one package.

Firstly, the X-300™ is a powerful web-based temperature logging instrument that allows you to monitor and control temperatures via an IP network. Up to 8 temperature sensors can be connected at a time, and temperatures can be viewed in real-time using a web browser. In addition, the X-300™ has many advanced features including email alerts, relay control, a BASIC interpreter, and much more.

Secondly, the X-300™ is a 7-day programmable web-enabled thermostat. Users can adjust and set temperatures for heating and cooling systems and view current indoor and outdoor temperatures from any web browser. As a web-enabled thermostat, it provides an attractive control web page that works great on desktop computers as well as smartphones such as the iPhone mobile phone.
