Castle
GA213 & GA215 Sound Pressure Level Meters 'A' and 'C' frequency weighting (toggle)'Slow' and 'Fast' Time constants (toggle)Sound Pressure (Lp) to 0.1dB resolutionLmax - maximum Lp hold (rms)Pmax - maximum peak levelElapsed time (running time hrs, min, sec)Overload and Under-range indicationHoused in a tough, crack resistant ABS plasticBattery condition (life approx. 24 hours) GA213 Sound Level Meter:A simple-to-use instrument that is fully compliant with IEC 61672-1:2002 Class 2 and IEC 60651:1979 Type 2. This is a necessary requirement for carrying out most noise assessment tasks in industry.Simultaneous rms and peak measurementDesigned for use by Industrial Safety Officers, Occupational Nurses and Engineers for general survey use in health and safety and engineering applications. Gives clear results to International standards requirementsSimultaneous measurement of Lp, Lmax, and Pmax GA215 Integrating Sound Level Meter:A feature packed instrument that is fully compliant with IEC 61672-1:2002 Class 2, IEC 60651: 1979 Type 2 and IEC 60804: 2001 Type 2. This meter gives simultaneous Leq (rms. average) and peak measurement for assessments to the Noise at Work Regulations 1989 and general engineering applications.Designed for Industrial Safety Officers, Safety Managers and Engineers for compliance with the Health and Safety as Work Act; Noise at Work regulation 1989. Will provide necessary information for completing risk assessmentsIntegrated equivalent level (Leq) measurementPersonal Sound Exposure Level (Lex) was Lep'dSimultaneous measurement of Lp, Leq, Lmax and PmaxNote: For compliance with the Noise at Work regulations and relevant international standards, sound level meters should be calibrated before use and checked afterwards. See later in this section for GA601 acoustic calibrator. A kit (KA010) case for protecting your GA215/GA213 and GA601 is also available.
