The MD-S270T wireless digital thermometer is a digital thermometer with wireless digital output powered by a lithium battery. It has a built-in high-precision PT100 sensor that can accurately display the temperature in real time, and has the characteristics of high accuracy and long-term stability.
This digital thermometer is equipped with a large-size LCD display and built-in MCU. With the mature 4G network of telecom operators, it realizes the wireless transmission of the on-site pipeline temperature to the cloud.
The product adopts 304 stainless steel shell and joints, which have good shock resistance and can measure gas, water, oil and other non-corrosive media to stainless steel.
The product function is practical, the upload rate can be set, the temperature collection frequency can be set, and the pressure real-time alarm function is provided. Once the temperature is abnormal, the alarm data will be sent immediately, and the alarm temperature value can be set.
In addition, it also has a variety of temperature unit switching, error resetting, and sending status query functions, which are especially suitable for areas that require unattended and remote monitoring, such as fire pump rooms, urban water supply, and petrochemical industries.
