Precision Dual-Sensor Temperature Controller

Dimensions: 77 x 34.5 x 58 mm. Weight: Not specified. Operating temperature range: -5°C to 55°C. Storage temperature: -30°C to 85°C. Relative humidity tolerance: 10–90% RH (non-condensing). Power supply: 230 V AC ±10%, 50/60 Hz. Relay rated current: 8 A at 220 V AC for refrigeration, defrost and fan circuits. Input: Two sensors — standard probe (-50°C to 120°C) and PTC probe (-50°C to 150°C). Display resolution: switchable between 1°C and 0.1°C. Accuracy: ±0.5°C within -30°C to 50°C (standard probe); ±1°C outside that range. PTC probe accuracy: ±1°C within -30°C to 50°C; ±2°C elsewhere. Sensor cable length: 2 metres (includes probe). Housing material: plastic. Colour: black and red. The controller supports precise temperature monitoring and regulation via two independent sensor inputs — ideal for dual-point control or redundancy. It features a clear digital display with user-selectable resolution, enabling fine-grained adjustments in critical cooling or defrost cycles. The relay outputs are rated for standard refrigeration system loads, including compressor, defrost heater and evaporator fan control. Designed for integration into domestic and light commercial refrigeration units, cold rooms, fermentation chambers and environmental test enclosures. Suitable for use in kitchens, laboratories, breweries, wine cellars and food storage facilities where stable, repeatable temperature management is required.
