PID Single Zone, Programmable Controllers

HTS/Amptek® single zone controllers pair auto-tune PID logic with solid state switching in a rugged metal case. Every controller accepts thermocouple or RTD sensor input and features very easy programming.

Choose a bench-top unit for portable and laboratory use, or a wall-mount unit for fixed installations. Limit versions add an independent over-temperature safety circuit that protects your product and equipment. For precise temperature control from a bench-top or wall-mount, we recommend the BT-15 or WM-15.
