    The Models 105 & 106 are part of the NEW generation of Pulsar Instruments
    acoustic calibrators that allow you to quickly check the accuracy of your sound
    level meter or dosemeter thus complying with International regulations and codes of practice.
    Great care has been taken during the design process to ensure that the units are comfor table to hold, robust and easy to
    use, whilst performing accurately throughout a wide range of temperature, humidity and pressure conditions.
    In use they fit over the microphone of the instrument and produce a stable 1kHz tone at 94dB, the frequency and sound
    level repectively, as mandated by the standard.
    The Model 105 meets the precision of Class 1 of IEC 60942, while the lower cost Model 106 meets industrial Class 2.
    The calibrators are powered by an easy to access single 9 volt battery giving many months or even years of operation. An
    automatic shut-off circuit ensures power conservation should you forget to switch the unit off after calibrating.
    Both units fully meet the requirements of IEC 60942, the Model 106 at Class 2 level, and the Model 105 at Class 1 level. The IEC
    60942 reference conditions are 25ºC, 101.3kPa pressure and 65% RH.
