Bass Meter with functionality of connecting external sensors

  • Frequency range from 10 to 120 Hz
  • Calibrated according to TERM-LAB Classic and Magnum
  • Amplitude range from 100 to 190 dB
  • Allows connecting microphone, power sensor or SPL-sensor
  • USB and Lab-Bus ports for connecting Next-Lab sensors
  • Software for some Android and Windows


The multifunctional sound pressure meter USB Bass Meter (Second Edition) is intended for measuring the noise level and sound pressure at low frequency. The device has an extended amplitude range up to 90 dB! The device can be connected to Windows PC or smartphone/tablet PC via USB port. Using the solid-state sensor allows receiving results with accuracy of 0.1 dB. The device is simple in use and does not require additional setting and calibration. A distinctive feature of this device is the Lab-Bus port for connecting external sensors of the NEXT-LAB series. Provided there are external sensors, it allows taking measurements of not only sound pressure, but also the voltage-current characteristics of electric circuits (when using the NEXT-LAB Power Sensor), amplitude-frequency characteristics or noise level of the acoustic system over the entire audible range (when using NEXT-LAB RTA Microphone). Also, if additional NEXT-LAB SPL Sensor is connected, it is possible to measure the sound pressure from two sources simultaneously.


The device is performed as a monoblock containing the high accuracy solid-state pressure transducer, analogue-to-digital converter and USB interface for connecting with a PC and Lab-Bus port for connecting external sensors. At the back cover, there are vacuum suction cups for affixing the device to any smooth surfaces such as glass. The case of the device is made of shockproof plastic material.

Next-Lab Power Sensor

The device for measuring the power characteristics of signal and power circuits
  • Lab-Bus digital bus
  • Internal dual-channel ADC
  • Measuring direct current circuits(Hall sensor version only)
  • Measuring alternating current circuits with frequency up to 15000 Hz
  • Contactless current sensor from 1 to 1200A(Hall sensor version) or to 400A(Power Clamps version)
  • Measuring voltage from 1 to 300 volt
  • Measuring power up to 360 kW(Hall sensor version) or to 120 kW(Power Clamps version)
  • True RMS algorithm


New power sensor is intended for use together with data analysis units such as Next-LCD and Next-USB. The device has an internal dual-channel ADC. The signal is digitized inside the sensor and is transmitted in digital form via the Lab-bus. This prevents distortion and noise pollution of the measured signal in the process of transmitting. The signal can be transmitted over a cable of a distance up to 10 meters. It is important to note that the sensor has an electric protection system for preventing injuries when working with high voltage and current circuits. The Next-Lab Power Sensor is an all-purpose meter for taking voltammetric characteristics of power and signal circuits as well as it can perform measurements of both high values up to 300 volt and 1200 ampere and small values from 1 volt and 1 ampere in direct and alternating current circuits. In addition to measuring current and voltage, it is possible to measure power, impedance, frequency, harmonic distortion coefficient, amplitude-frequency characteristic and waveform of a signal. For measuring the alternating current/voltage and power, the True RMS algorithm is used. The sensor takes measurements of direct current and voltage (power) used by car amplifiers, as well as alternating current and voltage (power) delivered by the amplifiers to subwoofer or other acoustic components. The device can be connected to the audio path, for example, between car audio and amplifier, for measuring and estimating the low current circuit characteristics, such as amplitude, waveform, AFC and coefficient of harmonic distortion. The Next-Lab Power Sensor can carry out measurements and evaluate quality not only of the car electrical system but also of home and industrial electric networks with power up to 360 kW with voltages up to 300 V and current up to 1200 ampere.


The device is performed as a monoblock, combining the contactless current sensor, dual-channel ADC module, electric protection system and Lab-Bus interface. The device has one Lab-Bus port for transmitting data and RCA jack for measuring voltage or for connecting the low current signal source. The current sensor has an opening for cabling of a diameter up to 22 mm. The case of the device is made of shockproof plastic material.
