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 Keller’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.
