The CERTO CT 2501 is a Ultra High Accuracy Length Gauge which features a measuring range of 25 mm.

The CERTO CT 2501 Length Gauge features a measuring range of 25 mm.

The high accuracy and measuring steps of 10 nm and less permit use of the CT 2501 in gauge block calibration. Thanks to its generous measuring range much larger than with inductive length gauges the number of reference standard blocks required can be reduced significantly.

A CERTO length gauging system comprises:

- CT 2501 Length Gauge
- ND 281 Display Unit
- Control box
- Gauge stand
- Ceramic suction plate as support surface

The total error of the CT 2501 over the entire measuring range of 25 mm lies within 0.1 m at ambient temperatures between 19 and 21 C and with temperature fluctuations of 0.1 K during measurement.

When the CERTO is used with length error compensation, e.g., in conjunction with the ND 281 Display Unit, HEIDENHAIN guarantees a total error of 0.03 m over the 25 mm measuring range.
