Key Features
- Wide Sensing Range: Measures from -50 degreesC to +110 degreesC with 0.1 degreesC resolution, covering freezing applications to high-temperature process control.
- Dual Mode Operation: Easily switch between heating mode and cooling mode via the settings menu - one module handles both scenarios.
- Powerful Onboard Relay: Built-in 10A relay directly switches heaters, fans, compressors, pumps, or solenoid valves without requiring an external relay board.
- Waterproof NTC Probe Included: Stainless steel-tipped, sealed sensor probe can be submerged in liquids or placed in humid environments for accurate readings.
- Adjustable Hysteresis: Set the temperature differential (0.1 degreesC-15 degreesC) to prevent rapid relay cycling, extending the life of both the relay and connected equipment.
- Configurable Delay Timer: Add a 0-10 minute delay before the relay activates to protect compressors and other equipment that require rest periods between cycles.
- Temperature Offset Calibration: Fine-tune readings by +/-7 degreesC to compensate for sensor placement or cable length variations.
- High & Low Alarms: Set upper and lower temperature boundaries; the display flashes and alerts you when thresholds are breached.
- Bright LED Display: 3-digit red LED readout is clearly visible even in dimly lit workshops, enclosures, or server rooms.
- Simple 3-Button Programming: Intuitive SET / + / interface makes configuration fast - no special tools or software required.
- Compact & Lightweight: Tiny 48 x 40 mm footprint fits inside project enclosures, electrical panels, or custom dashboard cutouts.
- Low Power Consumption:
