The 7250LP low pressure digital pressure calibrator can easily automate low pressure test and calibration workload. The 7250LP is easy to use, easy to maintain and has the reliability, performance, and features you want.
The 7250LP low pressure digital pressure calibrator, part of the versatile Series 7250 family, is specifically designed to meet the demanding performance requirements of calibrating low pressure sensors, transducers, mechanical gauges, portable calibrators and their plug-in modules. To accommodate bidirectional devices, the 7250LP can be supplied to operate in both positive and negative gauge modes. The 7250LP offers unmatched performance and enhanced control stability.
Utilizing multiple ranges in a single instrument, the 7250LP combines precision, stability, speed and affordability. The 7250LP has a unique quartz sensor, the most accurate pressure sensing technology available in a digital pressure calibrator. Each quartz sensor is manufactured and tested to provide the ultimate performance required by a Fluke Calibration pressure calibrator, ensuring that every customer receives the highest quality, precision and stability in their instrument.
|Model 7250LP||Select from three range combinations: 10 in H2O and 30 in H2O or 20 in H2O and 60 in H2O or 35 in H2O and 100 in H2O|
|Optional Modes||Vacuum (negative gauge)
Other Series 7250 digital pressure controllers are available in a variety of ranges from 5 to 3000 psig (350 mbar to 207 bar).
|Precision||0.005% of reading from 10% FS to 100% FS. Fixed error of 0.005% of 10% FS from 0% to 10% FSPrecision is defined as the combined effects of linearity, repeatability and hysteresis throughout the operating temperature range.
Expression of accuracy (uncertainty) conforms with the recommendations of the ISO guide to the expression of uncertainty in measurement.
|Stability||0.0075% of reading, per year|
|Control Stability||Active mode : 0.004% of each range Passive mode: no additional uncertainty|
