Hantek HT2018B - car battery tester

Gas leak detector with alarm that detects, among others, methane, carbon monoxide, hexane and acetylene. It is equipped with a very sensitive sensor. The measurement result is displayed on a small LCD screen in the form of a bar graph.

The PZEM-031 energy consumption meter is a device for internal use with a large LCD display that measures voltage, current, active power and energy in the voltage range of 6.5-100V DC and current 0-20A. It comes with power alarm, data memory and backlight control functions, but does not include additional cables or accessories.

A portable combustible gas detector designed to detect methane, propane, and isobutane. The device features a 2.0" color TFT screen, three alarm modes (audible, visual, and vibrating), and a flexible 36 cm probe for easy access to hard-to-reach areas. A response time of less than 5 seconds and the ability to record up to 30 alarm events ensure fast and precise threat detection. Fnirsi GD-02

The MCC USB-TC data acquisition system enables data reading from thermocouple-based temperature sensors. Digilent 6069-410-021

Portable frequency and phase analyzer based on NanoVNA-H4, designed for precise comparison of signals in the range from 1 MHz to 300 MHz, ideal for testing 10 MHz clocks, among others. With a touch screen, data logging and a built-in 2000 mAh battery, it is a mobile tool for engineers and electronics enthusiasts who require high measurement accuracy. tinyPFA

A detector that can detect hidden objects behind walls, such as metals, live electrical cables and wood. Equipped with a display with indicators and an audible alarm. Fnirsi WD-02

Ionising radiation detector (a.k.a. dosimeter or Geiger counter). It is used to measure the dose of ionising radiation, i.e. the amount of energy that is absorbed by an organism or material during exposure to radiation. It is capable of detecting three types of radiation: X-rays (X-rays), Y-rays and β-rays. Fnirsi GC-01 Blue

Li-Fe battery monitor that can measure voltage, current, power during charging and discharging, and watt-hours consumed and run time. The user can use a mobile application and a computer to control the measuring module. Juntek KG110F
