The Sentry Calibrator provides a low cost method to obtain better performance from older sensors or less accurate newer sensors. A low cost sensor that has +/- 2% accuracy but is repeatable may be brought into +/- .5% accuracy by using the Sentry Calibrator. The Sentry Calibrator also provides a way to perform sensor calibration "in circuit" with minimum system down time. Both DIN rail and wall mount options are available.
