The F4T is Watlow's next-generation process controller. Featuring a touch-screen interface, it's exceptionally easy and intuitive to use. The F4T is based on field-hardened electronics and robust algorithms already deployed in hundreds of thousands of installations worldwide. Watlow and TestEquity have worked closely together to refine this controller for use in TestEquity Environmental Chambers.

Why TestEquity chooses Watlow Controllers...
TestEquity has been using the original Watlow F4 controller since we began manufacturing environmental chambers in 1998. Prior to that, we relied on previous-generation Watlow controllers during the years that we sold reconditioned chambers. With their roots going back to 1922, Watlow has grown in product capability, market experience and global reach. The company holds more than 415 patents and employs 2,000 employees working in nine manufacturing facilities. TestEquity leverages Watlow's standard products because they offer the most reliable, field-proven, and fully supported designs.

F4T Features and Benefits

Profile archiving and transfer via USB Flash Drive

Profiles can be exported and imported as individual files via USB flash drive. This is useful for transferring profiles between different chambers and for archival purposes. The profile files contain all the profile steps that would ordinarily be entered via the front panel or Composer software. The complete F4T Configuration File (snapshot of controller configuration and all profiles) can also be easily exported and imported via USB flash drive.

Data Logging with transfer via USB Flash Drive or LAN

Data Logging can be enabled at any time and will log your choice of parameters to a .csv file. Log intervals from 0.1, 0.2, 0.5, 1, 2, 5, 10, 15, 30 seconds, 1, 2, 5, 10, 15, 30, 60 minutes can be selected. All datalog files are stored in internal memory until transferred to a USB flash drive or via LAN.

Graphical Trend Display

Provides a graphical display of your process values and set points over time. The snapshot screen capture feature lets you save the trend chart image to a USB thumb drive.
(Requires a key-code to add Trend Graphing to older F4T controllers. Contact TestEquity for the cost to upgrade your F4T.)

F4 Compatibility Mode

For the purpose of making an easy transition from the F4 to the F4T controller using Modbus, a special set of the most commonly used F4 registers were created. In the F4 Compatibility Mode, commands for Temperature/Humidity Set Point, Actual Chamber Temperature/Humidity, and Event Outputs are identical to the F4, so you can used your existing software on the new F4T.

SCPI Commands

The F4T accepts SCPI commands for reading the chamber temperature/humidity and reading/writing the temperature/humidity set point via Ethernet port 5025. The complete command set for all functions remain available via Modbus.

The F4T allows you to easily create profiles...

...directly on the Touch-Screen Display, or on your PC and upload them to the F4T Controller with Composer Software!

F4T Retrofit Kit Available for Existing TestEquity Environmental Chambers

Add a modern controller to your existing TestEquity temperature chamber or temperature/humidity chamber. The F4T fits in the same cutout as the original F4 controller. Simply remove the original F4 controller, replace it with the new F4T controller, and attach the wires. You will need to drill holes to accommodate the added Ethernet and USB connectors if you want that additional functionality.
