About this item
- INSTANT ZERO SLIDER CALIBRATION：Experience stress free lesson preparation with the side mounted calibration slider designed for rapid resetting. Teachers can now guide an entire class through experiment setups within seconds without needing external tools or tiny screwdrivers. This streamlined adjustment mechanism glides smoothly and locks firmly into place ensuring that every physics demonstration begins with absolute consistency. Eliminate setup confusion and redirect precious classroom minutes back to active scientific discovery.
- ACCURATE EXTENDED DUAL SCALE：View force and mass together through the clear dual graduation displaying up to 10N and 1kg. The flat box design positions the bold high contrast pointer directly against the measurement grid eliminating traditional reading mistakes caused by shifting viewing angles. Students can confidently record reliable mechanical data from the front or side of the laboratory bench reducing errors in their physics reports.
- SUSTAINED HIGH SPRING PRECISION：Invest in long term reliability with an internal suspension system featuring high fatigue resistant steel. Unlike standard instruments that suffer from tension loss after repeated stretching this robust component maintains its springiness over multiple academic terms. The spring reliably returns to the exact zero position after every load test ensuring that the middle measurement intervals remain highly precise and consistent.
- RELIABLE RESILIENT HOUSING PROTECTION：Protect your laboratory inventory from accidental bench drops with the heavy duty translucent casing. Manufactured from thickened impact resistant material this outer shell shields the inner mechanics from the daily rigours of a busy educational environment. The transparent cylinder design allows a full view of the internal spring mechanics during extension and extends the service life of your equipment.
- EFFICIENT GROUP LAB PACK：Optimise collaborative learning environments with this practical two piece instrument set tailored for science departments. Supplying multiple units allows pairs of students to engage directly with the equipment at the same time fostering teamwork and practical skills. This set arrives ready for immediate use in secondary school science curriculums mechanics workshops and homeschool learning spaces.

I wrote to Bigamart's customer support and they accompanied the process of reshipping the item until it finally arrived. I felt a genuine effort to solve the problem till it was finally solved.

The package was here in Australia from England in a few days — so quick! Something was missing and they refunded it straight away. Pretty happy with these guys.
