XN260 INFRARED THERMOMETER

Public Area Thermal Camera Infrared Thermometer System

This infrared body temperature measuring device XN260 has a measurement range of up to ± 6-10 meters. This system is also equipped with a body heat tracking camera (thermal camera). And also this tool is able to detect several faces at once that fall within the range of the camera.
It is suitable to be installed in a wide public area / public service as a measure to prevent the spread of a disease with an initial indication of rising / high body temperature.
Has a blackbody measurement system. If in an area there is a fairly crowded human crowd, then this can affect the accuracy of body temperature measurements. By using this system, this can be minimized so that measurement results can be obtained that are far more accurate.

RF Explorer 6G Combo

RF Explorer is a handheld digital spectrum analyzer, a very affordable tool for work in all popular frequency bands. It is based on a highly integrated frequency synthesizer and double-balanced mixer which offers high performance, compact size, low consumption and low cost.

It has been designed to be used equally well indoor and outdoor, and can be connected to a PC for extra functionality using standard mini-USB 2.0 connector.

This model includes a 6G baseline unit plus an RFEMWSUB3G Expansion Module conveniently assembled and tested. It comes with two SMA connectors and three antennas: a nice dual band telescopic 144/430MHz wideband telescopic antenna for all Sub-GHz frequencies, a rubber duck 5.8 GHz and a whip helical for 2.4GHz band. Additional, specific band antennas may be needed to cover efficiently some of the frequencies supported.

The combination of these two models offer coverage for most used communication frequency range used in modern communication technologies including WiFi, Bluetooth, Wireless Audio and Video, LTE, GSM, GPRS, Satellite, CATV, DTV, etc.
RF Explorer 6G Combo
Features

  • Pocket size and light weight
  • Solid aluminum metal case
