Designed with a 40,000 PSIG pressure range, Fluke Calibration’s P3840 is part of the P3800 series of hydraulic deadweight testers. The P3840 is crafted to increase reliability and improve accuracy. Constructed with tungsten carbide manufactured pistons, long-term stability is always ensured.
The deadweight tester comes supplied with all the required items for operation, like an oil reservoir, adjustable feet, test station and a premium quality hand pump, making the P3840 an overall comprehensive value.
Pressure Range | |
500 to 40,000 psi 40 to 2,600 bar 4 to 260 MPa 40 to 2600 kgf/cm2 | |
Accuracy* | Standard accuracy is 0.02% of Reading1 |
*Accuracy is based on % of Reading from 10% to 100% of the piston range when used in accordance with the corrections found on the calibration certificate. Below 10%, ± (accuracy class) x 10% of the piston range. | |
