FAQ:

Q1: How accurate is this B-Type spirit level?

A: The level ruler maintains a measurement error rate strictly below 0.1% (equivalent to 0.5 mm/m in standard position), meeting industrial precision requirements for construction and engineering.

Q2: How does the fluorescent magnified vial help in low-light conditions?

A: The vial fluid contains a light-gathering fluorescent pigment, paired with an optical magnifying lens. This amplifies ambient light and magnifies the bubble for clear 180-degree viewing at dusk, indoors, or in night-time work areas.

Q3: Will the magnets hold firmly on vertical round pipes and steel beams?

A: Yes. The embedded high-strength magnets provide continuous, secure holding power on flat steel surfaces, beams, and round iron pipes, allowing safe hands-free leveling.

Q4: What is the MOQ and turnaround time for OEM orders?

A: Standard packaging MOQ is low; custom brand printing, custom colors, and retail packaging require an MOQ of 1,000–2,000 pcs. Mass production turnaround is typically 25–35 days.
