PIECAL Frequency Calibrator with Totalizer

The PIECAL 541 is the best tool for calibration, test, and diagnosing turbine meters, frequency counters, vibration systems, tachometers, vortex shedders, integrators, and any other Frequency devices in the shop, plant and/or field. The Model 541 brings all the features you would expect from a frequency calibrator and timesaving new ones. The model 541 comes with an LED indicator showing gate time for easy trigger level adjustment. Make adjustments with the EZ-Dial™ Knob or test limits with the dual action EZ-Check™ Switch. Save hours of troubleshooting time on problems when compared to other calibration methods. When calibrating a totalizer, the model 541 eliminates the need of a stop watch. This calibrator will automatically stop when the selected number of pulses has been sent to the totalizer.

Features

• Accuracy: ± 0.005% of range
• 5 ranges from 1CPH to 20.000KHz for source and read
• Totalize inputs/outputs from 1 to 99999 in 1.0 to 100.0 minutes.
