產品名稱：數字碳纖維卡尺

Designed for the lab
Switch from inches to millimeters at the touch of a button. Great for use in measuring scratch or damage sensitive materials. Will not corrode when used on tissue or other wet materials. This caliper will measure up to 6" (152mm).
The graduated scale on the caliper body is for approximate reference only. The exact measurement (accurate to ±0.1mm/0.01") is shown on the LCD display.

Zeroes at any point
Zero button instantly sets unit to zero when jaws are at any position. This permits setting a Floating Zero™ or reference point to read “greater than or less than results with a minus sign displayed” without calculations. Ergonomic design, precision calipers are ideal for measuring outside or inside diameter. Easy to read, large digital display is 1/3" (8.5mm) high.

Traceable to NIST for accuracy
No lubrication is ever required on the ultra-smooth slide bar. Runs on the supplied battery for 10,000 hours. Made of strong composite carbon fiber. To assure accuracy an individually serial-numbered Certificate is provided from an ISO 17025 calibration laboratory accredited by A2LA. It indicates traceability to standards provided by NIST (National Institute of Standards and Technology).
