NA-28 Sound Level Meter and 1/ 3 octave band real-time analyzer

Sound Level Meter and 1/ 3 octave band real-time analyzer NA-28 IEC 61672-1: 2002 Class 1 IEC 61260: 1995 Class1 ANSI S1.4-1983 Type 1 ANSI S1.11-2004 Class 1 priorities for on-site measurements are speed, ease of use, quality and reliability. The New NA-28 is the top of the Rion range of sound level meters and analyzers. It combines cutting edge technology with excellent quality and unrivalled ease of use Applicable specifications IEC 61672-1: 2002 Class 1, IEC 61260: 1995 Class 1, ANSI S1.4-1983 Type 1, ANSI S1.11-2004 Class 1 Measurement functions With both a sound level meter mode and analyzer mode, it is capable of simultaneous main channel and sub-channel measurement in either mode. Time and frequency weighting are set separately for the main and sub-channels. Measurement modes Sound level meter mode: Measurement of all-pass values indicated in the measurement items below in the main or sub-channel, Measurement of either Lpeak or Ltm5 in the sub-channel Analyzer mode : Real-time octave and 1/ 3 octave band analysis and all-pass measurement in the main channel, Only all-pass measurement in the sub-channel Measurement items Simultaneous measurement of all items in the selected time weighting and frequency weighting characteristics Instantaneous sound pressure level Lp, Equivalent continuous sound pressure level Leq, Sound exposure level LE, Maximum sound pressure level Lmax, APMax and BandMax can be selected as maximum, Minimum sound pressure level Lmin, Maximum 5 time ratio sound level LN ( 1 to 99% , 1% Step) , Calculation from Lp or Leq 1sec Measurement time 1 to 59 sec, 1 to 59 min, 1 to 24 hours Microphone and preamplifier Microphone UC-59, Preamplifier NH-23 Measurement range A: 25-138dB, C: 33-138dB, Z: 38-138dB Frequency Range 10 Hz-20 kHz Time weighting Main: Fast, Slow, 10ms Sub: Fast, Slow, 10ms, Impulse Display Color semi-transparent TFT-LCD display with backlight ( 240 X 320 dots) Power requirement Four IEC R14P ( size" C" ) batteries or external power supply Operating time Manganese batteries: R14PU, 6 hours Alkaline batteries: LR14, 16 hours ( 10 hours if backlight is continuously activated) Dimensions and weight 331 ( H) X 89 ( W) X 51 ( D) mm , approx. 730 g ( including batteries) • Real Time Octaves ( 16 Hz to 16 kHz) or 1/ 3 octaves ( 12.5 Hz to 20 kHz) • Real Time Simultaneous Octaves ( 16Hz to 8kHz) and 1/ 3 Octaves ( 12.5Hz to 12.5kHz) • Data stored as text files direct to CF card • Measures and logs eq, max, min and 5 percentile values ( LN) in octaves and/ or 1/ 3 octaves • Auto Stores 300 000 data sets or 1 000 hours of 1 second 1/ 3 octaves onto 1 GB CF card • Auto Stores 1000 data sets or 10 000 of 1 second 1/ 3 octaves to internal memory • Manual Storage for 1 000 data sets internally or 100 000 data sets to 1 GB CF card • Linearity 110 dB in Sound Level Meter Mode and 95 dB in Analyzer Mode • 16 hours battery life with 4 Alkaline" C" Cells • Main and Sub-Channel for simultaneous selection of 2 time or frequency weightings F( Fast) , S( Slow) , 10 ms Time Weightings plus Peak & Impulse on Sub-Channel • Data transfer using CF card or USB ( meter/ CF card appearing as virtual disk) • Measurement can be started by internal or external trigger • Comparator output to trigger external devices • AC and DC outputs of main and/ or sub-channel • Expandable functionality using programme cards Distributor agent menjual service repair jasa perbaikan alat, upgrade perbaikan mesin balancing, repair perbaikan mesin balancing, rubber testing, laboratory equipment, universal testing machine, tensile test, metal detector, x-ray machine, conveyor metal detectors, metal detektor, conveyor weighing system, non destructive testing, eddy current testing, level transmitter, level sensor, level switch, data logger, orion, slope monitoring, alat ukur tanah, uji tanah, measurement and testing, thermocouple, proximity sensor, pressure switch, load cell, strain gauge, rotary encoder, oil analyzer, oil analysis, vibration level meter, sound level meter, rubber testing equipment, repair & upgrade Rheometer, repair & upgrade Mooney Viscometer, repair & upgrade Ozone Testing Chamber, repair & upgrade Carbon Black Dispersion, repair & upgrade Tensile Testing Machine, repair & upgrade UCAN, kalibrasi Rheometer, kalibrasi Mooney Viscometer, kalibrasi Ozone Testing Chamber, kalibrasi Carbon Black Dispersion, kalibrasi Tensile Testing Machine, kalibrasi UCAN, maintenance Rheometer, maintenance Mooney Viscometer, maintenance Ozone Testing Chamber, maintenance Carbon Black Dispersion, maintenance Tensile Testing Machine, maintenance UCAN, Rheometer, Mooney Viscometer, Ozone Testing Chamber, Carbon Black Dispersion, Tensile Testing Machine, Machine protection, Online condition monitoring, Reciprocating compressor, Reciprocating pump, condition monitoring systems, Prognost Indonesia, Robert Shaw switch, windrock, Hoerbiger, Maintenance reciprocating compressor, Cara terbaik memproteksi mesin , Level Measurement, Level Control, Level Monitoring, ukur level, tank level, control system, temperature control, remote monitoring, monitoring system, Borescope, soil test, soil testing equipment, condition monitoring, safety protection reciprocating compressor, Noise analyzer, vibration analyzer, upgrade mesin uji, upgrade alat uji, upgrade testing machine, perbaikan alat uji, Shore hardness tester, IRHD hardness tester, VLRH hardness tester, Barcol hardness tester, Pusey & Jones hardness tester, Vickers hardness tester, Rockwell hardness tester, Plastic hardness tester, Sensors Displacement, sensors distance and position, sensors Laser Scanner, sensors Optical micrometers, sensors Infrared Temperature, sensors Custom designed, sensors Speed and length, sensor warna, dst.
