Keller provides a convenient, portable solution for calibration of their standard accuracy pressure transducers and depth sensors. Powered by a lithium battery (included) this lightweight calibration system is good for 200 hours of continuous operation before the battery needs to be changed. Like Kellerâ€™s digital indicators, battery change can be accomplished easily and without tools.
The Full-version system includes a transmitter power and input loop with the Standard-version does not. The Full-version requires additional 9V batteries or an AC power supply.
Accuracy is 0.1% FS which is good for transducers with error bands 0.5% FS and greater or two-point calibration checks on higher pressure transducers.
