Chalkboard Drawing Instruments Set Manufacturer,Supplier and Exporter in India
Product Code : SCL-M-11397
Engineered for
secondary and post-secondary instructional environments, this five-piece
geometry set facilitates high-visibility demonstrations on vertical writing
surfaces. Constructed from high-impact polystyrene and clear acrylic, these
instruments ensure dimensional stability and parallax reduction during
geometric construction. Compliant with standard metric and imperial educational
curricula, the set supports large-scale Euclidean drafting and technical
drawing modules.

Key Pedagogical Outcomes
· Integrated
Ergonomic Handles: Facilitates precise
instrument stabilization against vertical planes, enabling students to observe
accurate line-weight consistency and geometric alignment.
· Dual-Scale
Graduations: Supports simultaneous
conversion exercises between Metric and Imperial systems, reinforcing Applied
Mathematics standards.
· Transparent
Acrylic Compass: Allows for
unobstructed visualization of the pivot point and arc trajectory, critical for
demonstrating complex Euclidean constructions.
· High-Contrast
Markings: Ensures legibility
for students in tiered lecture hall environments, supporting equitable access
to visual instructional data.
· Universal
Marker Interface: Accommodates standard
dry-erase and felt-tip markers, allowing for multi-modal application across
both chalkboard and whiteboard surfaces.
International Logistics & Compliance
This instrumentation
set is prepared for international distribution via export-grade, double-walled
corrugated packaging to prevent warping during transit. All shipments are
available with ISPM-15 compliant crating for maritime freight. Documentation
provided includes the Manufacturer’s Authorization Form (MAF), Certificate of
Conformity (CoC), and detailed technical datasheets. The polystyrene and
acrylic components are UV-stabilized and tropicalized, tested for storage and
operation in environments up to 45°C and 90% non-condensing humidity without
degradation of scale accuracy.
