The noise measurement unit has two independent noise measurement circuits, allowing for dual measurement that can simultaneously perform measurements under different frequency weighting characteristics and time weighting characteristics with a single device.
■ Built-in real-time frequency analysis function 1/3 or 1/1 octave frequency analysis is possible with this single unit. (Main channel) ■ Dual measurement of main and sub-channels With two noise meter circuits, you can simultaneously measure with one frequency weighting characteristic (e.g., "A characteristic") while recording a signal with another (e.g., "C characteristic"), allowing for arbitrary selection of frequency and time weighting characteristics. ■ Equipped with a comprehensive data memory function Data can be saved in manual or auto mode. One block of memory is reserved for manual storage and two blocks for auto storage. ■ Equipped with an infrared remote control port Remote operation is possible with an infrared remote control that has 18 functions. ■ Backup function The settings for level range and frequency weighting characteristics of the noise meter are retained even when the power is turned off, allowing you to set it back to the same configuration as the last measurement simply by turning the power on. ■ Energy-saving design for continuous 8-hour measurement Achieves double the operating time of conventional models with alkaline battery specifications. ■ Large LCD display with backlight, enabling nighttime measurements.

basic information
■ Measurement Function Dual measurement of main and sub-channels is performed for a single input. Additionally, real-time analysis of 1/1 and 1/3 octave bands is conducted for the main channel. ■ Measurement Time - Automatic: 1 to 99 (units: seconds, minutes, hours) - Manual: Measurement continues until the stop switch is pressed ■ Measurement Level Range - A-weighting: 28 to 130 dB - C-weighting: 34 to 130 dB - FLAT: 40 to 130 dB ■ Measurement Frequency Range - 20 to 8000 Hz (including microphone characteristics) - 10 to 20000 Hz (amplifier only characteristics) ■ Analysis Frequency Range - 1/1 octave: 16 to 8000 Hz - 1/3 octave: 12.5 to 12500 Hz ■ Input Level Warning Displays OVER when above +8 dB on the blue scale and UNDER when below -65 dB on the full scale display ■ Memory Stores instantaneous values or calculation results in manual or automatic mode. Has 1 block of memory for manual storage and 2 blocks for automatic storage, kept separately. ■ Display Backlit LCD display, 192 x 192 dots ■ Power Supply Four AA batteries or AC adapter

Company information
We, Soki, have been challenging new ways to "measure" with our "technological capabilities" and "on-site capabilities" since our establishment as "Soki Shokai" in April 1986, based on our desire to "create a new century with measurement technology." As a specialized store in the surveying and measurement field of the Kanamoto Alliance Group, we will continue to focus on "rental of surveying and measuring equipment," "development of automatic measurement systems," and "development of original products." We are committed to working together as a united team to meet the expectations of all our stakeholders. We sincerely appreciate the continued support and patronage of our customers and partners.
