Aplab Limited
Aplab Track-Signal Test Meter incorporates Digital Signal Processing based design to provide high accuracy and stability. It is designed for level measurement of selected frequencies. It also provides functionality of AC and DC voltage measurements.The purpose of Track-Signal Test Meter is to make adjustments, control measurements and inspections on both audio frequency track circuits of types FTGS 46, FTGS 917 and also for TI21M type track circuits (now known as BI track 300) for the measurement of eight frequencies from 5700Hz to 8500Hz for metro applications. Its compactness and battery operation render the unit particularly suitable for portable applications in maintenance and for level measurement in communication systems.

CRYSOUND
CRY2301 Noise sensor is a new type of noise test equipment independently developed by CRY Sound for industrial grade applications. It can realize real-time noise time domain and frequency domain analysis with real-time spectrum analysis software. The product complies with such standards as IEC61672 (Class 1) and GB/T3785 (Class 1). CRY2301 integrates measurement microphone, preamplifier, data acquisition, and data communication in a compact structure. It supports an optional 1'' high-sensitivity microphone for extremely low sound pressure testing. CRY2301 uses a USB interface for data communication and power supply. As a composite USB device consisting of a USB Audio device and a HID device, it is compatible with 32-bit/64-bit Windows 7 and Windows 10 systems. CRY2301 is equipped with real-time spectrum analysis software for easy access to time and frequency domain measurements. The real-time spectrum analysis software supports frequency weighting and time weighting, and can perform acoustic analysis, such as noise statistical analysis, octave analysis, and FFT analysis.
