Omron, K3HB-H Series

Visual confirmation of judgement results through display colors that switch between red and green. *1
Capable of high-speed sampling at 50 times per second (20 ms).
High-resolution of 0.01°C with platinum-resistance thermometer Pt100 input. Thermocouple sensor inputs also support a resolution of 0.1°C for all ranges.
Temperature input shift is easily set using two points.

Series expanded to include DeviceNet models. *2
UL certification approval (Certification Mark License).
CE Marking conformance by third party assessment body.
Water-resistant enclosure conforms to NEMA 4X (equivalent to IP66).

1 Visual confirmation of judgement results is not supported on models that do not have an output or models that do not support DeviceNet. You can change the display color by setting it, but you cannot switch it based on the judgement results.
2 DeviceNet models have a depth of 97 mm.
