The STT700 is an exciting new addition to the SmartLine Temperature portfolio and upgrades the widely-used STT250 temperature transmitter. The STT250 has been Honeywell’s main temperature transmitter with many decades of in-field use. The STT700 is a direct replacement for the STT250 and thus is suitable for the majority of process applications including those for control and safety while delivering excellent performance at a low installed cost.
