Features:Battery PoweredIntegral Temperature SensorDesigned for a single External PT100 ChannelHigh Accuracy (Transmitter) +/-0.1°C/0.2°FConnects to your Local Wi-Fi NetworkDesigned for Easy Self-InstallationHighly Accurate - Designed to monitor temperature of your critical items with the highest possible level of accuracyWide Range - Monitor temperature over a wide range -200°C to +150°C (-328°F to 302°F)Ultra-Low - Use with one of PT100 probes to monitor your low and ultra-low temperature storage areasThe Diligence 600 WiFi PT100 Temperature Transmitter is designed to monitor an external high-accuracy PT100 probe and the ambient temperature of your storage and work areas with its integral sensor.The WiFi PT100 Temperature Transmitter (RF616) is a highly scalable solution, designed to monitor the temperature of your critical items by means of a highly accurate PT100 probe offering a wide range and capable of ultra-low temperature measurement, whilst also allowing for ambient storage and work areas with an integral sensor.Designed with your needs in mindWe've used knowledge and experience from over sixty years of developing, selling and installing temperature monitoring solutions to not only create a highly capable product that is based around your needs, but which is also adaptable to those needs as they change and evolve over time.Secure WiFi ConnectivityThe Diligence 600 WiFi Monitoring System has been designed around 2.4GHz WiFi (IEEE 802.11b/g/n) technology, allowing you to use your existing WiFi infrastructure without the need for a gateway or hub device.All data sent by the transmitters of your Diligence 600 WiFi Monitoring System to the Diligence Cloud, is in a non-human readable proprietary format. Transmitters open outbound TCP connections (TCP Port 8080) to send and receive TLS-encrypted data including time, recordings, alarms, settings and firmware updates. TLS is two-way using both client and server certificates, and the communication format is proprietary. Firewalls and content filters that intercept TLS traffic should not do so on this port.The Diligence 600 WiFi Monitoring System devices will turn the radio signal off between WiFi transmissions. The sensors do not offer any kind of web page and will not respond to any request on any port other than required by essential network services e.g., DHCP.The Diligence 600 WiFi Monitoring System devices will turn the radio signal off between WiFi transmissions and will not respond to communication.Powerful Data Storage and Management PlatformThe Diligence Cloud is most advanced data storage and management platform yet! It offers users a quick and dynamic way to access and drill-down into the data from any device that is being monitored.The Diligence Cloud Dashboard View delivers a concise overview of your estate of devices, to help you resolve issues more quickly, saving products, time and money.The Diligence Cloud provides secure, multi-user access to data records and audit trails, from any web-browser enabled device. It is fully scalable to meet the demands of monitoring multiple devices across multiple sites, in line with your monitoring, data logging and compliance requirements.
