With three models to choose from, our line of wireless temperature data loggers allow you to collect, monitor and manage temperature data via wireless communication in real-time. Avoid expensive "hard wired" installation costs for managing data. Synchronize your warehouse, laboratory and mobile applications with our 2-way "high-performance" radios. You can use up to 65,000 network addresses with our custom solutions.

Our software options allows user-selectable programming including:
    • alarm settings and notification options
    • database creation with supervisory controls
    • sorting options for products
    • tracking numbers, dates, locations, statistical analysis
    • real-time temperatures
and more.

Automatically transmit data at pre-selected intervals and review all of your temperature profiles first thing in the morning, or, at any time you choose.

Our RF products provide a low-cost approach to monitoring all of your temperature needs. With the use of our special relay units, wireless connections can be extended 3,000 feet or more for laboratory or warehouse applications. Long-range or short-range, we can meet your exacting requirements with our multi-version models. For mobile applications, our wireless data collectors can be configured for transmission ranges exceeding 1/2 of a mile.

Measurement data is maintained in each logger with a separate battery source from the radio frequency power source, so loss of wireless connection does not result in loss of recorded data. Continuous monitoring for Alarm Conditions and offsite notification via e-mail to PC or cell phone can be installed should the temperature exceed user-defined limits.

What are the advantages of the edl-RF?

Small size and completely waterproof; can be used outside and in damp conditions. In the event of a local AC power failure, the unit will transmit to the base station.

What are the disadvantages of the edl-RF?

Powered by batteries. The need to change the RF batteries may be greater if used extensively with the base station.

What are the advantages of the edl-RF2?

AC powered, so there is no need to change RF batteries. Long range transmission for transferring data.

What are the disadvantages of the edl-RF2?

The device is not waterproof and is for indoor use only. In the event of a power failure, communication will cease with the base station. However, the data logger will still continue to record temperature and the software (if configured) will send an alarm notification that communication has been lost with the logger (this is true for all our loggers).

What are the advantages of the edl-M5?

AC or battery powered. Long-range transmission for transferring data. Can be connected to a truck, trailer or placed within warehouse. In addition, waterproof case can withstand harsh conditions.

What are the disadvantages of the edl-M5?

If AC powered: in the event of a power failure, communication will cease with the base station. However, the data logger will still continue to record temperature and the software (if configured) will send an alarm notification that communication has been lost with the logger (this is true for all our loggers).

If battery powered: the need to change the RF batteries may be greater if used extensively with the base station.

Note: Actual performance of the edl-RF system varies in each environment. Marathon strongly recommends the evaluation of the product in the actual environment of the application. Marathon publishes specifications typically experienced by our customer instead of publishing theoretical performance characteristics.
