Pulsar Model 105 Class 1 Acoustic Calibrator

Pulsar Model 105 gives a standardised 1kHz tone - the frequency where all weighting networks are the same, at a pressure of 1 Pascal which is a sound level of 94 decibels. It has sensors to correct for temperature, humidity, barometric pressure and battery voltage so that it remains stable and accurate under almost any conditions where they are likely to be used. Most noise related regulations stipulate that the sound level meter or dosemeter is calibrated before each acoustic calibration session and checked again before turning the instrument off. Noise measurements made for ‘official’ use, such as industrial health & safety or environmental monitoring, are not valid unless correct calibration procedures have been followed. MODEL 105 FEATURES Advanced performance ensures that both models meet or exceed IEC 60942 accuracy requirements. Full PTB pattern approval awarded on both models. Ergonomic and robust design ensures comfortable use. Auto correction for temperature and barometric pressure. Auto switch off in normal mode and ‘permanent-on’ mode available. Low battery indicator. 94dB Sound Pressure Level. Fits ½ inch international standard microphones. ¼ inch adaptor available. Calibration certificate included.
