Page 10: Introduction: Qnw Tc 1 Temperature Controller
Introduction: QNW TC 1 Temperature Controller Intended Use The QNW TC 1 Temperature Controller is used with an associated Peltier-controlled cuvette holder to control sample temperature during optical measurements. Temperature control is achieved using the TC 1 Temperature Controller alone or along with a computer interfaced to the TC 1 Temperature Controller box, using the QNW T-App software provided. -
Page 11: Electrical Specifications
All power supplies for the TC 1 Temperature Controller must be single-phase, AC voltage, three-wire system (active, neutral, earth) and should be terminated at an appropriate power outlet receptacle that is within reach of the power cord. -
