Keller LEX1Ei Digital Manometer

Quick Overview

LEX1Ei Digital Manometer is a highly precise pressure indicator with available pressure ranges up to 1000 Bar suitable for hazardous area installations. The LEX1Ei is a micro-processor controlled, digital pressure measuring instrument with integrated max.- and min- function for testing and calibration purposes. Standard accuracy is 0.05%FS with optional precision of 0.025%FS and 0.01%FS. The LEX1Ei comes with ATEX certification for hazardous area use (intrinsically safe).

Accuracy ±0.05 %FS, with KELLER test report ex works (standard)
Keller uses pressure sources to calibrate its products that are at least four times more accurate than the product
to be tested. This enables us to produce products in our factory with an absolute accuracy of up to ±0,05 %FS.

Precision ±0.01 %FS / 0.025 %FS, with KELLER test report ex works
Additional measurement work and selection of a specific pressure transducer means that optimum repeatability is guaranteed for selected pressure transmitters and digital manometers. Owing to the residual measurement uncertainty of the pressure sources used at its factory, KELLER cannot provide any verification of measurement accuracy at scales below ±0.05 %FS for these ultra-precise devices. KELLER therefore uses the term "precision" to denote the ability of a pressure transmitter or manometer to repeat measured values within a tolerance of 0,01 %FS based on the pressure sources used at the factory.

Accuracy ±0.01 %FS with DakkS (German accreditation body) certificate, issued by an external accredited calibration laboratory
By calibrating the zero point and performing amplification via the digital interface, an accredited calibration laboratory (ilac.org) can adapt ultra-precise KELLER products to their more accurate pressure sources and record the results. External calibration to an accuracy of up to ±0.01 %FS is performed in accordance with the guidelines set out by the German Calibration Service (DKD) and is conducted under reference conditions without any consideration of long-term effects.
