【Reliable Clamp Multimeter with True RMS】Accurate AC/DC voltage current, resistance, capacitance, frequency, temperature, diode, continuity test and non-contact AC voltage detection, the Clamp Meter is fully functional and easy to use for labs factories radio-technology and household..
【Auto-Ranging with NVC】The meter will automatically select the appropriate auto range.
NCV detects the existence of AC voltage on conductors and cables in-wall, troubleshooting electrical problems in a safe and user-friendly way.
【Clamp Measuring】Clamp jaw measures AC current up to 28mm without interrupting the circuit, which makes it much safer to use on mains cables and high current loads in vehicles.
【Continuity Test & Overload Protection】 Designed to Safely and Accurately Confirm the Circuit Electricity with Low Voltage Indication and Overload Protection. Light Alarm If Detects the AC Voltage(90V-1000V) or Live Wire..
【Features】high resolution, large backlit LCD screen and clamp light to improve visibility in dark place. Low battery display and automatic power off after 15 minutes inactivity. A soft zippered pouch included keeps everything neatly together and organized.

...ter is 30dB to 130dB with fast response speed and stable and reliable performance. Sound level meter is a high-precision noise meter with an accuracy of ± 2.0 dB. Real-time monitoring can give you accurate data on the sound level in the area.
❤【A / C Double-weighting Measurement】 The A-weighting simulates the frequency characteristics of low-intensity human ear noise, which is suitable for the detection of ambient noise. The C-weighting simulates the frequency properties of high-intensity noises of the human ear, which are suitable for the sound pressure analysis of machine motors and machines. More professional measurement methods provide users with a more perfect user experience.
❤【Fast and Slow Response Rate Conversion】 The spl meter has the function of converting the fast and slow response rate. The fast response rate uses a time constant of 125 milliseconds for general environmental measurement. The slow response rate uses a 1 second time constant, which is used for environmental measurements with relatively large changes in noise levels.
❤【Maintain the Maximum Value】Long press the MAX key to lock the maximum value measured during the measurement. Note that db meter does not have data logging and saving capabilities. If there is ....
