A new streamlined controller

ESPEC makes operating an environmental test chamber easier than ever with the new P-300 controller. An updated ‘tabbed’ user interface allows faster access to any screen. Standard USB and optional Ethernet interfaces make programming and data acquisition much simpler. In addition, improved algorithms make control faster and smoother.

Improved programming and data collection via computer

  • Standard USB port for uploading and downloading test programs and operation datalogs.
  • Optional remote monitoring, programming, and data collection via our Ethernet/LAN-based Web Controller
  • Direct access via an optional RS-232 serial port or GP-IB/LabView.

Energy-saving operation

Built into the P-300 controller are improved control algorithms for more efficient chamber operation. Invisible to the end user, the P-300 uses advanced control of an electronic expansion valve to save energy and improve control of the refrigeration system. Additional improvements in refrigeration and heater operation make the new generation of ESPEC Platinous chambers the most energy efficient ever.
