Send Inquiry

We are the reckoned entity in the industry for manufacturing and exporting highly functional range of Temperature Controller. These devices are manufactured by implementing advanced micro- controllers technology with automatic cold junction compensation suitable for thermocouples. Our entire stock of Temperature Controller is widely supplied to many industries for use in cold storage rooms, chilling plants and environmental chambers. Our clients can get these controllers from us in different models at nominal prices.

Features

  • Reading offset facility
  • High accuracy
  • Light in weight
