New P-300 controller with USB

The exclusive ESPEC P-300 controller has USB and Ethernet features to make programming and data collection easier than before. The user interface uses tabs for faster access to any screen. Standard USB and optional Web Controller/Ethernet interfaces make programming and data acquisition much simpler. In addition, improved algorithms make operation faster and smoother.

DEMO: See how easy the P-300 is

USB port for upload/download of test profiles and test data

  • Test programs can uploaded or downloaded from the P-300 via USB thumb drive.
  • Create, edit, and store programs on a PC using the included Pattern Manager Lite software.
  • Accurate, repeatable testing by uploading the same program to multiple chambers.
  • Create your own back-up archive of programs, and get additional profiles from ESPEC's library.
  • Retrieve and download test operation data via USB thumb drive. Data timeframe is selectable.
  • For integrity, viewing test data on a PC and exporting to Excel requires included Pattern Manager Lite software.

Energy-saving operation

Invisible to the end user, the P-300 uses advanced cooling control via an electronic expansion valve, saving energy and improving temperature stability. Sophisticated future-looking algorithms make temperature ramping faster and smoother. These high-end features are unique to ESPEC. Additional improvements in refrigeration and heater operation will make the next generation of ESPEC chambers the most energy efficient ever.

Additional capabilities

  • Store up to forty programs, as well as three different constant-mode set-ups.
  • Multilingual display in English, Japanese, Chinese, or Korean.
  • Alarm diagnostics and history, plus a ‘back trace’ feature for troubleshooting.
  • Three programmable timers allow the user to set reminders for maintenance or other actions.
  • Energy saving by using only one compressor when testing above -10°C (for cascade refrigeration models).
  • Optional Ethernet/browser-based Web Controller access can also be used to upload and download programs, as well as data.
  • Optional Product Temperature Control allows faster ramping to the desired conditions on the sample.
  • Computer interface options for specialized programs: RS-232/serial or GP-IB.

Recommended: Web Controller

The ESPEC Web Controller is an embedded server/software solution for monitoring and programming your chamber via Ethernet. Works with P-300, SCP-220, F4T, & F4 controllers. That’s most ESPEC North America chambers built since 1997.

Independent of the controller itself, the Web Controller adds additional capabilities for datalogging, programming, alarm emails, and RESTful API.

P-300 Communication Options

 In a nutshell :

  • Web Controller: ESPEC’s most complete solution with Datalogging (CSV), profile creation, email alarms, Restful API. Browser-based application. API for app integration and Command pass-thru for Modbus. (Try live demo)
  • Chamber Connect Software: Simple ESPEC PC software will show status and log data while connected to the controller. Uses/requires RS-232 option (CSV). 
  • Free Chamber Connect Library: Basic code for connecting to P-300 for custom applications. Uses/requires RS-232 option. (Download at Github.com)
  • Standard USB port: Allows data downloading, also program upload/download. Must use Pattern Manager Lite software to convert to CSV/Excel.
  • Optional RS-232 or IEEE-488 ports for direct access, including via Chamber Connect Software & LabVIEW

NOTE: This guide for P-300 on chambers manufactured by ESPEC North America in the USA which includes USB port only. Chambers made in Japan have different remote access functionality.

Data Download

The P-300 supplied by ESPEC North America includes a USB port with two functions:

  • Data Download
    • Get all the stored data points from the controller or just a specific segment of time.
    • Use the Pattern Manager Lite software to view the data and export to a CSV file.
  • Program upload/download
    • Enables the user to save programs and swap between chambers.
    • Pattern Manager Lite software allows editing of the profile from a PC before uploading.

P-300 Remote Access Tips

  • The Web Controller can also be used to pass thru commands directly to the controller, essentially functioning as an Ethernet-to-serial converter.
  • ESPEC’s recommended software approach is using Python code to access the Web Controller’s API. (This is how the Web Controller was built.)
  • For LabVIEW, consider connecting to the Web Controller’s API instead of direct serial connection that requires drivers.
  • ESPEC chambers manufactured by ESPEC CORP. in Japan and sold in the USA include USB and Ethernet interfaces as standard, such as SU & SH benchtops and TSE & TSA thermal shocks. Please refer to equipment documentation for details of capability. The Ethernet interface has some functions as the Web Controller, but it is not the same.
