8X ETC-974 Digital Temperature Controller Microcomputer Thermostats Thermostat Refrigeration Alarm 2

Feature Highlights: 1. Dual-Probe Precision: Measures from -50°C to 110°C (-58°F to 230°F) with the standard probe, and -55°C to 140°C (-67°F to 284°F) with the optional PTC probe. Switch between 1°C and 0.1°C display resolution for detailed monitoring. 2. Reliable Accuracy: Delivers high accuracy of ±0.5°C within -30°C to 50°C (±1°C outside this range) for the standard probe. The PTC probe maintains ±1°C accuracy from -30°C to 50°C (±2°C otherwise). 3. Robust & Versatile Control: Features 8A/220VAC relays (for refrigeration, defrost, and fan) for dependable operation. It performs consistently in environments from -5°C to 55°C and 10%-90% relative humidity (non-condensing). 4. User-Friendly Design: Clear 1.9-inch digital display is easy to read. Its compact size (77 x 34.5 x 58mm) allows for flexible placement, either standing or wall-mounted. The included sensor cable is 2 meters long for convenient setup. 5. Complete 8-Pack Value: This package includes 8 x ETC-974 digital temperature controllers, perfect for managing multiple refrigeration units, incubators, or fermentation setups simultaneously. Product Details: This microcomputer thermostat is a versatile control center for your cooling and heating devices. It ensures precise temperature management for household and hobbyist applications like wine coolers, fermentation chambers, or aquariums. The bright digital display shows real-time readings, while the sturdy plastic housing and reliable relay outputs provide durable performance. Setup is straightforward with its standard sensor input and flexible power supply (230VAC ±10%). It also includes a refrigeration alarm function for added peace of mind.
