The RFRHTemp2000A is a two-way wireless temperature and humidity data logger with LCD digital display.  This device transmits up to 2000 ft maximum (outdoors unobstructed), and stores data internally using built-in memory.  Designed with external humidity and RTD based temperature sensors, the device provides a fast response time for both parameters.  It also 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.

Functions including starting, stopping, and downloading can be performed wirelessly using the RFC1000 wireless transceiver.  This allows for quick access to data so you can 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 RFRHTemp2000A 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 MadgeTech wireless data loggers and transceivers may be required). The RFRHTemp2000A utilizes the new MadgeTech Software, version 4.1. MadgeTech Data Logger Software is a powerful, analytic tool. Data can be viewed in graphical or tabular formats and summary and statistics views are available for further analysis. The software features export to Excel®, data annotation, digital calibration and more.

This device is calibrated and is available with a Calibration Certificate. The RFRHTemp2000A is ideal for both industrial or laboratory applications including supply chain storage facilities, incubator monitoring and HVAC studies.
