CAL 3200
CAL 9900
Compact 1/32nd DIN Autotune PID temperature controller
1/16th DIN Auto tune PID temperature controller

The model CAL 3200 was the world's first 1/32nd DIN (24mm x 48mm) temperature controller launched in 1992. The model is still in full production today.

For the very latest 1/32nd DIN controller, go to the 3300, which uses the same program menus but has the benefit of communications and latest aesthetic designs.

The CAL 9900 pioneered the market of digital 1/16th DIN (48mm x 48mm) temperature controllers in 1986.

The model is still supplied to many high volume customers.The latest 1/16th DIN controller is the 9400, which features much easier programming menus together with a communications option.

Key features of the CAL 3200 are:
