# 301 Standard Controller

**The 301 PID furnace controller has a large display mounted behind a smooth wipe-clean membrane and offers a single ramp to set point.** It includes a 99 hour process timer which can be programmed for a timed delay at the start of the process or used as a countdown timer.

## Standard features

- The standard controller fitted to the majority of laboratory furnaces and ovens
- Precise PID (proportional integral derivative) control
- Large clear illuminated display of the temperature
- The controller is covered by smooth easy to clean membrane panel

## Options (*specify these at time of order*)

- Optional over-temperature protection with a variable set point to protect either the furnace or load; selection of this option provides an additional independent thermocouple and protection circuit
- RS232 communications, permitting a single controller to communicate with a PC

The 301 furnace controller provides precise PID (Proportional Integral Derivative) control meaning that ramp rates and set points are very closely followed.
