Overview

The X-300™ is two products in one package:

Temperature Logging

First, 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 and/or humidity sensors can be connected at a time.

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.

Web-Enabled Thermostat

Second, 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 thermostat, it provides an attractive control web page that works great on desktop computers as well as smartphones such as the iPhone® and other mobile digital devices.

Examples

Temp Monitoring/Logging

Standard configuration for monitoring and/or logging temperatures.

X-300 Standard configuration for monitoring and/or logging temperatures.

Temp Monitoring with Alarm

Basic configuration for an alarm. When the temperature crosses a specific threshold, the alarm will be turned on or off. The alarm could be an audio device such as a buzzer or bell, an indicator such as a lamp, or a functional device such as a fan or heater.
