-w series in-place temperature display adopts imported chip to assemble high precision and high stability, error ≤0.5%, internal power supply, micro power consumption, stainless steel shell, strong protection, beautiful and delicate. -w series in-situ temperature display adopts imported high-precision, low-temperature drift, ultra-low power consumption integrated circuit and wide-temperature liquid crystal display. The built-in high-configuration battery can work continuously for ≥5 years without laying power supply cable. It is a new in-situ temperature display with high precision, good stability and strong applicability. It is an ideal substitute for the traditional bimetal thermometer.
