AUTENS

AUTENS Infrared Thermometer Tester -50°C~550°C Humidity Measuring

SKU CH-Z3N5-EM9F2

Handheld infrared thermometer measures surface temperatures from -50 °C to 550 °C and ambient humidity up to 99 % RH with a 12-point laser and 0.5 s response

  • Measures surface temperature from -50°C to 550°C in 0.5 seconds
  • 12-point laser shows exact measurement area for precise targeting
  • Built-in humidity sensor reads 0–99% RH alongside ambient temperature
  • Colour LCD backlight with data hold gives clear readings in low light
  • Auto power-off and battery indicator extend runtime between changes

Infrared Thermometer -50°C~550°C Range

This AUTENS handheld tester combines non-contact infrared temperature measurement with ambient temperature and relative humidity reading in one portable instrument. A twelve-point laser indicator shows the target area visually while the colour LCD backlight and data-hold function make readings easy to see in low light. The device delivers an infrared measurement in about 0.5 seconds and includes high/low temperature alarms with selectable °C or °F units. Power comes from two AAA batteries which are not supplied.

Suitable for Quick Surface Checks Not Medical Use

The gun suits technicians, HVAC engineers and DIY users who need fast surface-temperature checks on machinery, ducts, electrical panels or cooking surfaces up to 550°C. It also logs ambient conditions from -10°C to 60°C and humidity from 0 to 99%RH. Buyers who require clinical accuracy for human or animal temperature screening should look elsewhere because the supplier states readings on living subjects will not be accurate. Anyone needing internal temperature data or a calibrated laboratory instrument will also need a different tool.

±3°C Infrared Accuracy at Full Range

The single specification that decides fit is the infrared accuracy of ±3°C or ±(1.5%+2°C) across the full -50°C to 550°C span. If your application demands tighter tolerance than this, the tester will not meet the requirement. For general maintenance, spot checks and environmental monitoring where this tolerance is acceptable, the instrument provides a practical all-in-one solution.

Questions about this item

How often will the 2 x 1.5V AAA batteries need replacing with daily use?

The unit has auto power-off and low power consumption; battery life depends on how frequently the laser and backlight are used, but typical alkaline cells last several months of regular handheld measurements.

What is the first accuracy limit reached when measuring a surface at 550 °C?

At the top of the IR range the stated tolerance is ±3 °C or ±(1.5 % + 2 °C), so the percentage term becomes the dominant error component.

Does the 12-point laser or the colour LCD backlight make the gun noticeably warm during a full shift?

The infrared sensor responds in 0.5 s and the device draws little current; neither the laser array nor the display generates perceptible heat during continuous operation.
