An acoustic calibrator is a device which produces an acoustic pressure of defined level and frequency. In other words, anacoustic calibrator provides a template of acoustic pressure.

By using such a reference we can check the accuracy of the measurements taken by the sound level meter and adjust themif a drift error in the sensitivity is detected.

Features:

• SV 35A & SV 33A class 1 sound calibrators in accordance with IEC 60942:2003
• SV 34A class 2 sound calibrator in accordance with IEC 60942:2003
• Frequency 1 kHz
• 94 dB or 114 dB levels (SV 35A)
• 114 dB level (SV 33A, SV 34A)
• Built-in 1/2 MEMS reference microphone
• Microphone presence detection (SV 35A)
• Built-in temperature and static pressure compensation
• Automatic power off
• Dimensions 65 x 65 x 70 mm

The SV104 instrument is a revolutionary new approach to occupational health and safety noise monitoring offering voice comments and audio events recording functions which are a new concept in an instrument of this size.This personal dosimeter has a robust 1/2 MEMS microphone enabling easy calibration using most commonly available acoustic calibrators. The SV104 is a cable-free dosimeter and is typically attached to the users shoulder, close to the ear using the mounting clips supplied.

1. The SV110 is a hand-held vibration calibrator designed for verification of machine sensors as well as on-site checks of human vibration accelerometers in accordance to ISO 8041. The small size of SV110 enables easy checks of sensors at the machines. Depending on the selected frequency user may select level of calibration from1 m/s2 to 10 m/s2. Accelerometers are conveniently attached using mounting stud, mounting disc or dedicated adapter.
3. The calibrator menu provides selection between both metric systems g and m/s2. The menu is simply operated by three push-buttons and small OLED display.

Features:

• Hand-held vibration field calibrator designed in accordance to ISO 8041 for in-situ checks of hand-arm vibration metersand machine vibration meters
• Three push-buttons for selection of frequency and amplitude and start/stop control.
• The OLED graphical screen displays information on selected frequency and vibrationlevel.
• Two operating frequencies 80 Hz and 160 Hz
• Calibration of sensors with mass up to 300 g at 80 Hz.
• Built-in reference accelerometer for cross-axes / transverse vibration detection.
• Built-in rechargeable battery.
• Automatic fault detection: two LED diodes show the current status during the calibration process.
