Portable calibration rigs SPU-3

Our dealers

Purpose:

Portable calibration rigs of SPU-3 series are used for calibration of utility and household gas meters of standard sizes G1.6-G25 on site without dismounting.

Features:

  • Equipment compactness allows arranging the rig in one portable case;

  • Fully automated calibration procedure;

  • Wide dynamic range of flow rates 1:1,000;

  • Autonomous operation from the integrated power supply source up to 10 h;

  • The integrated printer for printing out the calibration protocol on site;

  • The rig's software allows keeping an archive of calibrations;

  • Data uploading to a PC via a USB-connector.

You can order the portable calibration rigs spu-3 from  dealers  at a good price.
