Wireless Temperature and Humidity Data Logger

The MATREC141 is a wireless temperature and humidity data logger with digital display. This device is calibrated traceable to N.I.S.T. and comes with a Calibration Certificate. The logger is ideal for both industrial or laboratory applications including supply chain storage facilities, incubator monitoring and HVAC studies. Designed with external humidity and RTD based temperature sensors, the device provides a fast response time for both parameters. For customer convenience, functions include starting, stopping and downloading from the device wirelessly using the MATACC109 wireless transceiver. This allows customers to quickly access data and spend less time maintaining the device. Data can be provided in real time back to a central PC, or the device may be downloaded at periodic intervals. The digital display provides the current reading for both the humidity and temperature channels with minimum, maximum and average statistics accessible for a quick snapshot of the logged data. The MATREC141 features user programmable alarm settings for both temperature and humidity parameters. An audible buzzer and LED alarm indicator notifies users when the temperature or humidity is above or below the threshold set in the alarm. Email and text alarms can also be configured and sent from within the software, allowing users to be notified almost anywhere. The logger can be used as a single, wireless data logging system, or it can be expanded to a large scale system, which can include hundreds of data loggers measuring a number of areas (additional wireless data loggers and transceivers may be required). The device utilizes new software, making it a powerful, analytic tool. Data can be viewed in graphical or tabular formats and summary and statistics views are available for further analysis.
