Key benefits Precise temperature control to keep processes stable, reducing drift and manual adjustments. Broad applicability for air conditioning systems, industrial machines, and fermentation processes. Builtin temperature calibration for onsite finetuning without external tools. Heating and cooling modes provide flexible control to reach and hold setpoints quickly. Safety features include and low temperature limits and audible/visual alarms for peace of mind. Compatible with devices requiring up to 20 A output for reliable performance. What makes it stand out Integrated calibration function enables quick, accurate tuning to your specific setup. Clear alarm system and limit settings help prevent unsafe conditions during operation. Straightforward operation and reliable performance across multiple applications. Core specifications Temperature range: 50 to 110 degrees Celsius Control accuracy: ±1 degree Celsius Output capacity: up to 20 A Modes: heating and cooling Calibration: builtin Safety: temperature limit, low temperature limit, alarms Applications: suitable for air conditioners, machines, and fermentation processes Use scenarios Scenario 1: use in an air conditioning or climate control system to maintain a stable outlet temperature for consistent comfort or process requirements. Scenario 2: install on industrial machinery to hold a precise operating temperature during production cycles, minimizing variations and improving product quality. Scenario 3: employ in a fermentation setup to keep a constant temperature with alarms to alert operators if the process deviates from the target.
