TEL72 / TEL96 Digital Oven Temperature Controller Knob Thermostat 400 Degree 96x96mm 72x72mm Relay Output K Input 380v Temperature calibrating

Compact digital oven controller (models TEL72 and TEL96) with knob operation and K-input for thermocouple connection. The front panel combines a digital display tube and LED indicator: the tube shows the measured temperature with high accuracy while the LED indicates current output status, and a dual-window layout displays set and measured temperatures simultaneously. Supports °C/°F readout. Two selectable working modes — Heating (start temperature is less than stop temperature) and Cooling (start temperature is above stop temperature). Measurement range from -50 to 110 with high temperature control precision of 0.1. Provides relay output and is compatible with 380v systems. Includes an audible buzzer for high/low temperature alarms and sensor-fault alerts, plus temperature calibrating for fine adjustments.
