UNI-T UT12E-EU PRO Line Voltage Tester This product comes with a 3-year warranty. The UT12E-EU is a professional non-contact AC voltage tester with a built-in lamp and a synchronised audible and visual warning function. In low-voltage mode, it is suitable for testing low-voltage motors (<90V), audio systems, arc welding machines, underground mine lighting, thick-insulated cables and other weakly electromagnetic devices. In high-voltage mode, it can be used for testing power lines in the range (90–1000 V), switchboards, electrical appliances and three-phase systems. It is widely used in the maintenance of low-voltage equipment, such as wires, cables, sockets and other electrical/electronic devices. It is a very useful tool for electricians. Simply place the sensor head near the object to be tested or the AC socket. When alternating current voltage is detected, the red or green LED on the tip lights up and the buzzer sounds. The frequency of the buzzer and the detection LED increases as the detector approaches the object being tested.

UNI-T UT309E PRO Infrared Thermometer The UT309E professional non-contact infrared thermometer can quickly and accurately determine surface temperatures ranging from -35 °C to +850 °C by measuring the infrared energy radiated by the target surface. For easier and more intuitive targeting of the device onto the target surface, a dual-wavelength rotating laser is built in, which indicates correct targeting of the thermometer. The distance-to-spot ratio is 20:1 with this instrument. This thermometer also features IP65 protection against water and dust and can withstand a drop of up to 3 metres. It is possible to preset the emissivity of the measured surface within the range of 0.1 to 1.0. The display of preset functions and measured values is provided by a clear, high-contrast EBTN colour display, whilst limit values are indicated by LEDs. You can set the system time and schedule repeated measurements in the future with a maximum interval of up to 96 hours between two measurements, and store up to 99 measured values in memory. The measurement time is also stored for each stored value. For these measurements, you will use the built-in standard socket for mounting on a tripod. The temperature measurement time is up to 250 ms in 95% of cases. It is possible to set minimum and maximum value limits, and measurements outside this range are indicated by an audible and visual signal. It is possible to display minimum, maximum and average temperatures, as well as deviations from the average (MIN, MAX, AVG, DIF). The thermometer switches off automatically to reduce power consumption if not used for 8 seconds. This automatic switch-off can be disabled.
