Instruction Guide

① Center & place the device at face level

Place the device so the small circle is level with your forehead. The device can be attached via double-sided tape or the included magnet. Please see 'Installation' for more details.

② Power Options

When using batteries, turn the power switch to the up position. The power switch is located on the upper right side of the device. If you are using a USB-Type B cable, please leave the power switch in the down position. When you first turn it on, an alarm will sound 3 times and the LED will turn red and then blue. The LED will then turn off.

③ Wait 15 minutes for the automatic calibration.

When you first turn on the device, the thermal sensor will calibrate to the surrounding temperature within 15 minutes. Although you may use the device before that, there is an increased risk of inaccuracy. Please use with caution.

When the power is on, the device operates as follows:

While active The center LED flashes blue once every 60 seconds.
Upon detection
  • 99.5℉ (37.5℃) or higher: The center LED flashes red and an audible alarm will sound.
  • 95-99.5℉ (35-37.5℃): The center LED will flash blue.
  • 99.5℉ (35℃) or lower: The temperature is too low and the LED will not activate. Please wait for your body temperature to rise or move the device to a warmer area.
Upon low battery 3 audible alert sounds mean the battery is low. Please
change the batteries. Full batteries typically allow for
300 hours of continuous use.

If your body temperature is too low, the LED will not activate. Please wait for your body temperature to rise. Long hair, glasses, and masks that cover the forehead may prevent an accurate body temperature from being taken. Uncover your forehead to insure an accurate temperature reading.

Installation

Mounting via magnet

The back side of the device is fitted with a high-powered magnet embedded in the center. When placing the magnet, be careful not to pinch your fingers. The product is shipped with the embedded magnet and double-sided tape. When using the magnet for attachment, please do not remove the tape.

Mounting via double-sided tape

When installing via double-sided tape, be sure to clean the surface for dust, oil or grime prior to installation. If dust, oil or grime are not removed sufficiently prior to installment, the device may fall. Please use with caution. 

Power Options

Power via Batteries

Slide the device up to access the battery casing and insert 4 x AA batteries. Turn on the power switch to activate the device.

Power via micro-USB

With the power switch turned off, insert a micro-USB Type-B cable into the micro-USB port. Micro-USB cable is not included.

Frequently Asked Questions (FAQ)

  • Can this device be used outdoors

    Using this device outdoors may cause a large increase in the margin of error for detection. The device is not waterproof or water resistant and may be damaged by moisture. Using the device indoors out of direct sunlight in a room with a temperature ranging from 77.0 to 82.4℉ (25 to 28℃) is recommended.

  • Can this device be used indoors at temperatures of 86.0℉ (30℃) and above

    The recommended temperature range for indoor use is 77.0 to 82.4℉ (25 to 28℃). If the environmental temperature is significantly higher or lower than this range, it may cause an increase in the margin of error for detection.

  • How long does it take the THERMOGATE ZERO to measure temperatures

    Detection time is approximately 0.5 seconds. If you want to make sure the measurements are especially precise, we recommend standing still in front of the unit for at least one second.

  • What is the appropriate distance from the device for measurement

    Stand 12 to 20 inches (30 to 50 cm) away from the device for measurement.

  • Can the temperatures of multiple people be measured at the same time

    Unfortunately, no. Please measure each person’s temperature one at a time.

  • How many hours can the device be continuously used for?

    When using alkaline batteries, the device can run with the power continuously on (24 hours a day) for around 12 days (approximately 300 hours). Actual performance may vary depending on environmental conditions.

  • Can temperature records be saved?

    This device does not save any measurement records.

  • Can the detection temperature settings be changed?

    The detection temperature cannot be changed.

  • Why do I hear a continuous beeping sound from the device?

    This means the batteries are low. Please change them soon!

  • Why doesn’t the blue LED turn on sometimes?

    During colder seasons, the colder temperatures may lead to a body temperature below the allowed minimum detection level of 95℉ (35℃), and the blue LED may not light up. It will light up once every 60 seconds when operating normally. Please move the device to a warmer area if this is not the case.

  • The red LED turns on and the alarm sounds when no one is in front of the device. What’s happening?

    If the device is pointed at a window, mirror, or reflective surface that is exposed to heat such as sunlight, the device may be attempting to measure this heat source as a person. Please move the device to a different location or place it at a different angle.

  • Can the device measure temperature through clothing?

    The device measures the temperature of the surface of the skin, so measurements cannot be taken through clothing. Using the exposed forehead is recommended for measurements – this allows for masks to be kept on as well. Please be sure to place the device at an appropriate face-level.

  • Why does the device turn off when I use a mobile battery to power it over USB?

    This device uses a low-power current, so some mobile batteries automatically cut off power to these kinds of devices. Please use an IoT compatible mobile battery instead.

  • Can I return this product?

    We do not accept returns for any reason other than a defective device. For more information, please refer to our return policy page.
