Dual Mode Control for both heating and cooling applications, this digital controller automatically maintains your desired setting with 0.1 C precision, making it suitable for a wide range of industrial and hobbyist uses. /Low Alarm Set upper and lower limits to prevent excursions; the controller triggers an audible alert when temperatures exceed your preset range, providing an extra layer of protection for sensitive equipment. Precise Digital Display Clear miniature display with 0.1 C resolution and a 0.5 s refresh rate. It delivers realtime temperature readings from 55 C to 120 C via its 1 m waterproof metal probe. Easy Calibration Builtin calibration function allows you to adjust readings as needed, guaranteeing accurate management for critical processes in laboratories, greenhouses, or fermentation setups. Use scenarios Laboratories: maintain precise temperatures during critical processes or incubations to ensure consistency and protect sensitive samples. Fermentation setups: keep a stable temperature to improve product quality and repeatability. Greenhouses and plant propagation: regulate heating or cooling and receive audible alerts if temperatures drift outside safe ranges to protect young plants and delicate growth stages.
