RF140 - Wireless High Temperature Data Logger
The RF140 is a wireless, real-time high-temperature data logger that combines the trusted performance of the HiTemp140 Series with the convenience of remote monitoring. Designed for demanding environments where temperature accuracy is critical, the RF140 records precise, time- and date-stamped data while communicating via Bluetooth® with the MadgeTech 4 Data Logger Software and the MadgeTech App, providing immediate visibility into critical processes.
The RF140 is engineered to withstand harsh environments commonly found in pharmaceutical manufacturing, healthcare, food processing, and industrial applications. By delivering data in real time, users can monitor conditions as they occur, receive instant notifications of alarm conditions, and respond quickly to process deviations without waiting for a study to be completed.
The RF140 operates within a standard temperature range of -40 °C to +140 °C (-40 °F to +284 °F) and is available in various probe lengths to accommodate a wide range of applications.
In addition to storing more than 60,000 time- and date-stamped readings, the RF140 continuously transmits data via Bluetooth® to the MadgeTech 4 Data Logger Software and the MadgeTech App, enabling live monitoring, customizable alarms, and immediate access to critical information. The logger’s onboard memory ensures every reading is captured, while automatic Bluetooth reconnection seamlessly synchronizes any data recorded during temporary communication interruptions. This combination of real-time monitoring, automatic synchronization, and secure onboard storage ensures a complete and uninterrupted record of your monitoring session.
