WiFi Thermocouple Transmitter
The WiFi Thermocouple Transmitter is a highly flexible and highly capable device within the Diligence 600 WiFi Monitoring System, that leverages the extended temperature range of a thermocouple sensor, making it perfectly suited to critical applications involving low and ultra low temperature storage as well as high temperature applications.
Highly Flexible
Supports both extended range Type K Thermocouple probes as well as the increased accuracy of Type T Thermocouple probes across two different connection types.
Combine with a Type T Adaptor and ultra low temperature air probe to measure the temperature of your low and ultra-low temperature storage areas.
High Temperature
Combine with a Type K Adaptor and high temperature air probe automate the temperature monitoring in those hazardous areas.
Secure WiFi Connectivity

The 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.
Diligence Cloud
Powerful Data Storage and Management Platform

The Diligence Cloud is our 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.
