Digital manometers Keller have received an extended recalibration interval – 2 years!

The entire range of digital pressure gauges from our catalog has once again successfully passed technical and metrological tests at the D. I. Mendeleev All-Russian Scientific Research Institute of Metrology. Based on the test results, a certificate of type approval for these measuring instruments was obtained.

Thanks to the high results demonstrated by the pressure gauges during many years of stable operation in the Russian market, as well as the successful tests conducted by FSUE VNIIM, the instruments have gained recognition and earned the high trust of specialists at the metrology institute. As a result, the verification interval for the instruments was extended to 2 years even for the most precise solutions (0.025% FSO).

The two-year verification interval will not only reduce the frequency of annual verification procedures but also save resources for enterprise metrology departments on the costly procedure of accuracy confirmation at territorial CSMs. Additionally, the new type approval certificate for the measuring instruments line from KELLER factory has been supplemented with two new devices: ECO-2 and dv-01 OEM.
