Description
Key Features
- SD Card Real-Time Data Logger: Saves measuring data along with time information (year, month, date, hour, minute, second) into the SD memory card, enabling easy download to Excel for further data analysis without extra software.
- Frequency and Time Weighting: Designed to meet IEC 61672 Class 2 standards. A & C weighting networks comply with standards. Time weighting options include Fast (125 ms) and Slow (1 s) for accurate response to varying sound levels.
- Wide Measurement Range: Measures sound levels from 30 to 130 dB with auto and manual range selection. Offers precision linearity over a wide range (100 dB) and displays Leq and SPL measurements.
- User-Friendly Design: Features a large LCD with green backlight for easy reading, data hold function, peak hold, and memory recall for maximum and minimum values. The instrument also includes a built-in clock and calendar for time-stamped data logging.
- Advanced Connectivity: Includes RS232/USB computer interface for data output, enhancing data management and integration with other systems.
- Durable and Portable: Constructed with a heavy-duty and compact housing case, making it easy to carry and use in various environments. Long battery life with low power consumption.
Optional Accessories:
- Sound Calibrator (94 dB), SC-941
- Sound Calibrator (94/114 dB), SC-942
- Sound Wind Shield Ball, SB-01
- SD Card (2 GB)
- USB Cable (USB-01)
- RS232 Cable (UPCB-02)
- Data Acquisition Software (SW-U801-WIN)

| Circuit | Custom one-chip of microprocessor LSI circuit. |
| Display | LCD size : 52 mm x 32 mm LCD with green backlight ( ON/OFF ). |
| Measurement Range | 30 - 130 dB. |
| Resolution | 0.1 dB. |
| Function | dB ( A & C frequency weighting ), Time weighting ( Fast, Slow ), Peak hold, Data hold Record ( Max., Min. ). |
| Accuracy | Characteristics of " A " frequency weighting network meet IEC 61672-1-2013 class 2 Under 94 dB input signal, the accuracy are: 31.5 Hz ± 3.0 dB Temperature 63 Hz ± 2.0 dB Operating Less than 85% R.H. 125 Hz ± 1.5 dB 250 Hz ± 1.5 dB 500 Hz ± 1.5 dB 1 K Hz ± 1.0 dB 2 K Hz ± 2.0 dB 4 K Hz ± 3.0 dB 8 KHz ± 5.0 dB Remark : The above spec. are tested under the environment RF Field Strength less than 3 V/M & frequency less than 30 MHz only. |
| Frequency Weighting Network | Characteristics of A & C. A weighting : The characteristic is simulated as "Human Ear Listing" response. Typical, if making the environmental sound level Accessories measurement, always select to A weighting. C weighting: The characteristic is near the "FLAT" response. Typical, it is suitable for checking the noise of machinery (Q.C. check) & knowing the sound pressure level of the tested equipment. |
| Data hold | Freeze the display reading. |
| Peak hold | To keep the peak ( max. ) measurement value. |
| Time weighting | Fast - t = 125 ms * "Fast" range is simulated the human ear response time weighting. Slow - t = 1 s * "Slow" range is easy to get the average values of vibration sound level. |
| Range selector | Auto range : 30 to 130 dB. Manual range : 2 range, 30 to 80 dB, 80 to 130 dB, 50 dB on each step, with over & under range indicating. |
| Frequency | 31.5 to 8,000 Hz. |
| Microphone type | Electric condenser microphone. |
| Microphone size | Out size, 12.7 mm DIA. ( 1/2 inch). |
| Calibration VR | Build in external calibration VR, easy to calibrate on 94 dB level by screw driver. * Calibrated via external SOUND CALIBRATOR ( SC-942, optional ). |
| Calibrator | B & K (Bruel & kjaer), MULTIFUNCTION ACOUSTIC CALIBRATOR Type 4226. |
| Datalogger Sampling Time Setting range | Auto 1 second to 3600 seconds @ Sampling time can set to 1 second, but memory data may loss. Manual Push the data logger button once will save data one time. @ Set the sampling time to 0 second. @ Manual mode, can also select the 1 to 99 position ( Location ) no. |
| Memory Card | SD memory card. 1 GB to 16 GB. |
| Advanced setting | * Set clock time ( Year/Month/Date,Hour/Minute/ Second ) * Set sampling time * Auto power OFF management * Set beep Sound ON/OFF * Decimal point of SD card setting * SD memory card Format * Frequency weighting to A or C setting |
| Over Indication | Show " - - - - ". |
| Data Hold | Freeze the display reading. |
| Memory Recall | Maximum & Minimum value.(for SPL ) |
| Sampling Time of Display | Approx. 1 second. |
| Data Output | RS 232/USB PC computer interface. * Connect the optional RS232 cable UPCB-02 will get the RS232 plug. * Connect the optional USB cable USB-01 will get the USB plug. |
| AC output | AC 0.5 Vrms corresponding to each range step. * Output impedance : 600 ohm. |
| Power off | Auto shut off saves battery life or manual off by push button. |
| Operating Temperature | 0 to 50 ℃. |
| Operating Humidity | Less than 85% R.H. |
| Power Supply | * Alkaline or heavy duty DC 1.5 V battery ( UM3, AA ) x 6 PCs, or equivalent. * DC 9V adapter input. ( AC/DC power adapter is optional ). |
| Power Current | Normal operation ( w/o SD card save data and LCD Backlight is OFF) : Approx. DC 12 mA. When SD card save the data but and LCD Backlight is OFF) : Approx. DC 51 mA. * If LCD backlight on, the power consumption will increase approx. 30mA. |
