Adopts high-precision and high-resolution electromagnetic force balance sensor.
Equipped with a high-precision humidity sensor to effectively reduce the impact of environmental humidity on weighing; a high-sensitivity temperature sensor is adopted to effectively reduce the sensitivity to temperature changes.
Outstanding design with high cost performance, perfectly completing various weighing/measurement tasks.
LCD Display: Adopts LCD display with clear and bright screen and reasonable layout, facilitating users to read weighing results.
Transparent Glass Wind Shield: Enables multi-directional visibility of samples during weighing, and can also be disassembled and cleaned for quick cleaning.
Multiple Weighing Modes: Basic weighing, density detection mode, counting weighing.
Sensor Protection Device: Protects the sensor from damage during the transportation of the balance.
Optimized Product Structure Design: Improved design strength, with anti-leakage, anti-static and anti-corrosion properties. Stainless steel weighing pan, corrosion-resistant and anti-oxidation.
Built-in RS232 Bidirectional Communication Interface: Enables connection between the balance and computer, micro printer. It can also transmit weighing results to PC and other open applications.
Automatic Calibration System (Internal Calibration Only): When the temperature changes by 1.5℃ or the time since the last calibration exceeds 2 hours, the balance will automatically start the calibration function, avoiding potential factors such as failure to perform regular calibration or inaccurate external weights, making the user's weighing results more accurate and reliable, and reducing unnecessary operations (for internal calibration type balances only).
