DRAFT SHIELD SYSTEM
The transparent glass enclosure helps reduce the influence of:
• Air currents
• Laboratory ventilation
• Sudden environmental disturbances
• Operator movement around the weighing chamber
This improves measurement stability, particularly when weighing small sample quantities.
WEIGHING CHAMBER
The enclosed weighing chamber incorporates a durable metallic working surface designed for convenient cleaning and routine laboratory operation. The glass panels provide clear visibility of the sample during weighing.
DISPLAY
The instrument features a large illuminated digital display for clear observation of weighing results. The exact display resolution and readability should be confirmed from the instrument specification label or manufacturer’s technical documentation.
CALIBRATION
The balance includes a calibration function for maintaining weighing accuracy. Calibration should be performed using an appropriate certified calibration weight corresponding to the instrument’s specified capacity and accuracy class.
For quality-controlled laboratories, calibration and verification should follow the laboratory’s standard operating procedures and applicable quality-management requirements.
GOOD WEIGHING PRACTICE
For optimum performance:
• Install the balance on a stable and vibration-free laboratory bench.
• Level the instrument correctly before use.
• Avoid locations with strong air currents or direct ventilation.
• Allow the instrument to stabilize after switching on.
• Keep the draft shield closed during precision weighing.
• Use clean and appropriate weighing vessels.
• Avoid touching samples or weighing vessels directly with bare hands when high precision is required.
• Allow samples to reach suitable laboratory temperature before weighing.
• Perform routine calibration and performance verification.
SAFETY AND OPERATING PRECAUTIONS
• Operate the instrument on a stable, level and dry surface.
• Protect the balance from excessive vibration and impact.
• Do not exceed the specified maximum weighing capacity.
• Keep liquids and corrosive chemicals away from electronic components.
• Clean chemical spills promptly using an appropriate procedure.
• Use the correct power supply specified by the manufacturer.
• Disconnect the instrument before maintenance or extensive cleaning.
• Handle the glass draft shield carefully.
CLEANING AND MAINTENANCE
• Switch off and disconnect the balance before cleaning.
• Remove loose sample residues carefully.
• Clean the weighing chamber with a soft, suitable laboratory cloth.
• Avoid abrasive cleaning materials.
• Do not allow liquids to enter the electronic housing.
• Keep the glass panels clean for clear visibility.
• Periodically verify balance performance using suitable certified reference weights.
• Arrange professional servicing when required.

WLS QUALITY INSIGHT
A precision electronic balance with a glass draft shield is an essential instrument for laboratories requiring reliable measurement of small sample masses. The enclosed weighing chamber helps minimize environmental interference, while the digital control functions support routine analytical, research and quality-control weighing operations.
IMPORTANT TECHNICAL NOTE
The exact manufacturer, model number, maximum weighing capacity, readability, repeatability, linearity, calibration method, weighing units, power requirements and communication interface are not clearly identifiable from the available image.
These specifications should therefore be verified from the equipment nameplate, packaging, operating manual or official manufacturer’s technical documentation before publication or procurement.
WLS does not recommend assigning unverified numerical specifications to laboratory equipment.
