Multifunction Level Meter for Audio Band "LM-332"

The chassis form has been completely renewed, improving operability and robustness! With the addition of new features, convenience for on-site work has also increased!

The "LM-332" is a handheld multifunction level meter that is the successor model to the LM-322, equipped with the necessary functions for testing and maintenance of audio bandwidth transmission paths, transmission devices, and communication equipment. The casing has been newly designed to enhance robustness and features a waterproof structure (excluding measurement terminals). Additionally, it has a built-in speaker for monitoring audio signals, allows for two-way communication via a dedicated 4W line, and enables continuity checks with a buzzer sound. 【Features】 ■ Composed of an oscillator, level meter, DC voltmeter, AC voltmeter, and ohmmeter ■ Handheld type with high performance ■ Measurement values are displayed digitally for direct reading ■ Peak hold function allows for maximum/minimum value retention ■ Capable of measuring the answer tone of fax machines and modems *For more details, please refer to the PDF materials or feel free to contact us.

Broadband Selection Level Meter 'SPM-101'

The fluctuations of the input signal can be visually confirmed! With the signal search function, it demonstrates its power in exploring unknown signals.

The "SPM-101" is a transmission characteristic measurement device capable of measuring the characteristics of various transport devices and communication equipment across a frequency range of 20Hz to 6.4MHz. It houses an oscillator and a selective level meter in a single unit, allowing for the switching of selectable filters with bandwidths (BW) of 6Hz/70Hz/3.1kHz. With a maximum input level of +40dBm for 75Ω unbalanced connections, an external attenuator is not required. 【Features】 ■ Equipped with an oscillator and a selective level meter (frequency settings can be selected for linked or unlinked operation) ■ Bandpass filters (BPF) with three bandwidths: 6Hz/70Hz/3.1kHz ■ The display section of the level meter features both an analog meter and a digital display ■ No external attenuator is needed with a maximum input level of +40dBm for 75Ω unbalanced connections *For more details, please refer to the PDF document or feel free to contact us.

Frequency Selective Level Meter SPM-40 Oi Electric

It is a frequency-selective level measuring instrument that covers the frequency range from the audio band to the carrier band.

Handheld and battery-operated. The measurement frequency range is from 100Hz to 2MHz. The measurement bandpass filter allows for the selection of three bandwidths (6Hz, 70Hz, 3.1kHz) and can also be used as a flat level meter without a filter. Measurement data can be recorded to an SD card of up to 2GB.
