A new line of thermometers is here! TQS4 thermometers with RS485 interface. It is a new iteration of very popular line - TQS3, which was improved in many ways. Main improvements are power voltage input, which is now up to 36 V DC, and even lower consumption. And for your convenience we've placed a jumper on the PCB that switches the unit into ModBus RTU without any hassle.

Communicaiton protocols have remained fully backwards compatile.

We've made four versions as there were with the TQS3:

• Outdoor version with high IP coverage (TQS4 O)
• Interior version (TQS4 I)
• Pipe mount version (TQS4 P)
• Bare electrionics board (TQS4 E)

We've made a complete documentation of communication protocols for your ease of integration. A C# library is also available on Github together with documentation and examples of use (documentation in Czech).
