Smart Instrument II

Smart meters (temperature, pressure, liquid level, GPS) Product Name: Multi-Parameter IoT Sensor (Dual-Pressure)  

Product Model: XT-TLQ-02  

Product Dimensions: L140mm × W140mm × H160mm  

Product Application: Primarily used for monitoring the internal liquid body temperature and air pressure of containers. Key data is uploaded to the clients server via 4G IoT technology, enabling clients to monitor the pressure conditions of on-site containers through computer or mobile terminals. Suitable for monitoring ton barrels, water tanks, oil tanks, sprinkler trucks, etc.
