Noise measurement equipment used to measure different noise levels and to ensure the authenticity and accuracy of these measuring devices, often the noise measurement equipment must be calibrated annually.
As a rule, noise measuring devices are on the list of equipment with strict requirements issued by the Directorate for Standards and Quality of Vietnam and under the state management authority of the Ministry of Science and Technology. LDT Joint Stock Company is a leading provider of top-notch noise measuring instrument calibration services in Vietnam.
Why use equipment calibration service?
• Ensuring the stable operation of the device,
• Timely detection of failures to prevent possible problems during work,
• Compliance and compliance with the provisions of law.
Calibration conditions
When carrying out calibration, ensure a quiet calibrated environment and the following conditions:
• Temperature: (20 ÷ 26) ºC;
• Air humidity: (25 ÷ 70)% RH;
• Calibration environment sound pressure level <75 dB.
Before conducting the calibration, the following preparations must be carried out:
• Equipment to be calibrated must be placed in the calibration environment for at least 1 hour and supplied according to the manufacturer's specifications and specifications.
• Calibration vehicles must be powered and warmed according to the specifications and regulations of the manufacturer.
• Record environmental conditions while performing calibration at least 3 times: at the beginning, during the process and at the end of calibration.
