You can easily tell if the liquid in the drum is full or empty with just one touch!

<Product Description> 1) Measurement can be easily done with a single touch, making the confirmation work for full and empty states hassle-free. - Pressing the white switch lights it up red, and it automatically stops after 3 minutes. - To resume, simply press the switch again. - When full or empty, a buzzer sounds for 15 seconds and flashes red. * Pressing the switch stops the sound. - The position of the sensor can be adjusted to set the liquid level line for full and empty states. 2) It uses batteries and can be used approximately 1,000 times with a single battery replacement. - It uses 4 standard alkaline batteries (AA size). - It also supports lithium batteries, which are twice as durable as conventional ones and last longer in cold environments. <Sensor Type Liquid Level Gauge for Full/Empty Product Specifications> Model: GDB-CF/GDB-CL Measuring Method: Sensor Type (Contact Type) Applicable Liquids: Low viscosity oil, kerosene, light oil, water, wastewater, waste liquid Recommended Battery: 4 AA alkaline batteries Liquid Temperature Range: 0℃ to 40℃ Size (mm): Φ97×265/97×1070 Weight (kg): 0.4/0.7
