Textronic industries offers a range of temperature controllers and indicators based on the most advanced micro-controller technology. These are the most reliable and highly accurate microprocessor linearized models, thereby enabling high quality production. Temperature is settable through e2prom [memory back-up facility] and through membrane-keys [feather-touch keyboard]. All models have user-friendly operation and programming, giving an accuracy of 0.2% and resolution of 0.1o up to 4 digits. Sensors used are rtd, pt-100 type. Different models like microtemp general, microtemp hysteresis, microtemp dual, microtemp pid/pwm, microtemp pid/thy, and microtemp ecojet are available.
