GSM Cutter with Balance
GSM Cutter with Balance
A GSM Cutter with Balance is a lab toolset used to determine the GSM (Grams per Square Meter) of fabrics, which indicates the fabric’s weight and density. The kit includes a GSM round cutter and a precision weighing balance.
Purpose GSM Cutter with Balance:
To accurately measure the weight per unit area of textile, paper, or nonwoven samples for quality control and product classification.
How It Works:
GSM Cutter: – A circular blade cuts a fixed area (usually 100 cm²) from the fabric.
Weighing Balance: – The cut piece is weighed, and the result is multiplied by 100 to get GSM.
GSM = Weight (in grams) × 100
Applications of GSM Cutter with Balance:
Textile and garment industry
Nonwovens and paper manufacturing
QC labs and R&D
Benefits of GSM Cutter with Balance:
Accurate GSM Measurement – Ensures precise fabric weight analysis for quality control.
Quick and Simple Operation – Allows fast sampling and GSM calculation in minutes.
No Need for Area Calculation – Cutter gives a fixed area (usually 100 cm²), simplifying the formula.
Improves Product Consistency – Helps maintain uniform fabric weight across batches.
Portable and User-Friendly – Compact design makes it ideal for labs and production floors.
Cost-Effective Tool – Offers high accuracy without the need for expensive equipment.
Versatile Use – Suitable for fabrics, paper, leather, films, and more.
Features of GSM Cutter with Balance:
Rotary Blade Cutter – Stainless steel blades for clean and accurate circular cuts.
Fixed Sample Area – Typically 100 cm², eliminating the need for area measurement.
Precision Digital Balance – Measures in grams with high resolution (0.01 g or better).
Rubber Cutting Pad – Protects blade and provides a smooth surface for cutting.
Safety Lock – Prevents accidental blade exposure.
Compact & Durable Design- Long-lasting, lab-friendly construction.
How to Use GSM Cutter with Balance:
Prepare the Fabric Sample- Place the fabric on the rubber cutting pad.
Cut the Sample – Hold the GSM cutter firmly and rotate it to cut a 100 cm² circular sample.
Turn on the Balance – Power up the digital weighing scale and tare it to zero.
Weigh the Sample – Place the cut fabric piece on the balance and note the weight in grams.
Calculate GSM – Multiply the weight by 100 to get GSM. – GSM = Sample weight (g) × 100
Record the Result- Log the GSM value for quality control or analysis.
Clean and Store – Wipe the cutter and balance, and store them safely after use.
GSM Calculation Formula:
GSM (g/m²) = (Weight of Sample in grams) × 100
When using a GSM cutter (100 cm²):
The cutter gives a fixed area of 100 cm², which is 1/100th of a square meter.
So, multiplying the sample’s weight by 100 gives the GSM directly.
Example:
If the sample weighs 1.75 g, then:
GSM = 1.75 × 100 = 175 g/m²
Balance Calibration Guide (Manual Calibration):
Warm-Up – Turn on the balance and let it warm up for 10–15 minutes if required.
Level the Balance – Use the built-in bubble level and adjust leveling feet until the bubble is centered.
Tare the Balance – Press the “TARE” or “ZERO” button to reset the display to 0.000 g.
Enter Calibration Mode – Press the “CAL” or “MODE” button (depends on the model).
– Some balances may require holding the button for a few seconds.
Use Standard Weight – When prompted, place a certified calibration weight (e.g., 100g, 200g) on the pan. – Wait for the display to stabilize.
Confirm Calibration – The balance will beep or show “PASS” once successful. – Remove the weight when done. Recheck Zero – Ensure the display returns to 0.000 g after removing the weight.
Tips:
Use certified weights for accuracy (Class F1 or E2).
Calibrate in a draft-free, vibration-free environment.
Calibrate daily or before critical measurements.
