Additional Information
Product Description:
GAOTek Dual Laser Infrared Thermometer (Wide Range, Full Accuracy) thermometer has a 50:1 optic ratio (target distance/diameter ratio), this enables users to measure small targets from a distance. The user stands a safe and comfortable distance from the target, points the thermometer at the surface to be measured, presses the button and instantly reads the temperature. Ideal for measuring the temperature of ceiling vents and hot pipes in the HVAC industry or any other item that is difficult to reach. This enables the user to measure most surfaces accurately and quickly.
Each unit incorporates a clear, easy to read, backlit custom LCD display that indicates both the temperature and the emissivity. The thermometer features a four-button keypad, allowing the user to select the mode required, i.e. max, min, differential and average temperatures, view the max/min high and low alarms and adjust the emissivity from 0.1 to 1.0 in 0.01 increments (default set at 0.95). It has an auto power off facility that turns the instrument off after 60 seconds, maximizing battery life. This function can be disabled, if required. The LED light and sighting laser can be disabled. It has a thread in the base for mounting on a tripod.
Display
Default screen
Simply aim the thermometer at the measure target with Lens (⑧) and press Meas. key (⑥) to display the surface temperature. The Distance: Spot is 50:1. The two laser points are the reference for the target spot size. Please make sure the target area is within the field of view.
Function:
- Press Emissivity key (①) for setting the emissivity
-
Press Emissivity key (①) then press up key (④) or down key (②) to set the emissivity, then press Mode key (⑤) to confirm it. The emissivity can be changed from 0.10 (10E) to 1 (100E). - Press Mode key (⑤) for scrolling more display function as follows.
| E | Here will show the emissivity data. (The default emissivity is 0.95.) |
| MAX/MIN/DIF/AVG | Press Mode key (⑤) for the Maximum (MAX), Minimum (MIN), difference between MAX and MIN (DIF) and Average (AVG) modes. During the measurement, the special modes reading will be displayed beside the mode icon |
| HAL/LAL | Press Up key (④) or Down key (②) key to change the High Alarm (HAL) or Lo Alarm (LAL), then press Meas. key (⑥ ) to confirm it. For example: When the reading 26.9 °C < LAL 27 °C, the Low icon will flash and you will hear a beep sound. |
| PRB | Connect the thermocouple with Thermocouple socket (⑪) and put the probe in/on the target, the thermometer will display the temperature automatically without pressing any button. To see the minimum or maximum data during the probe measurement, please hold down the Up key (④) or Down key (②). After measuring high temperature, the probe may remain HOT for a while |
** The thermometer will automatically shut off if left idle for more than 60 sec, unless in PRB mode. (In PRB mode, it will shut off if left idle for more than 12 minutes.)
ADD Value:
| In MAX, MIN, DIF, AVG mode: | Press Up key (④) for LOCK mode ON/OFF. The lock mode is particularly useful for continuous monitoring of temperatures for up to 60 minutes. |
| Press Down key (②) for °C or °F transferred. | |
| In all modes: First hold on the Meas. Key (⑥) | Press Up key (④) for backlight function ON/OFF. |
Press Down key (②) for laser function ON/OFF. (With flash light be turned on in the same time as laser ) |
CAUTION
- When device is in use, do not look directly into the two laser beams–permanent eye damage may result.
- Use extreme caution when operating the laser.
- Never point the device towards anyone’s eyes.
- Keep out of reach of all children.
STORAGE and CLEANING
It should be stored at room temperature. The sensor lens is the most delicate part of the thermometer. The lens should be kept clean at all times, care should be taken when cleaning the lens using only a soft cloth or cotton swab with water or medical alcohol. Allowing the lens to fully dry before using the thermometer. Do not submerge any part of the thermometer.
LCD ERROR MESSAGES
The thermometer incorporates visual diagnostic messages as follows:
 |
‘Hi’ or ’Lo’ is displayed when the temperature being measured is outside of the settings of HAL and LAL. |
 |
‘Er2’ is displayed when the thermometer is exposed to rapid changes in the ambient temperature. ‘Er3’ is displayed when the ambient temperature exceeds 32 °F to +122 °F (0 °C to 50 °C). The thermometer should be allowed plenty of time (minimum 30 minutes) to stabilize to the working/room temperature. |
 |
Error 5~9, for all other error messages it is necessary to reset the thermometer. To reset it, wait for auto power off, remove the battery and wait for a minimum of one minute, reinsert the battery and turn on |
 |
‘Hi’ or ’Lo’ is displayed when the temperature being measured is outside of the measurement range. |
BATTERIES
The thermometer incorporates visual low battery indication as follows:
When the ‘Low Battery’ icon indicates the battery is low, the battery should be replaced immediately with AAA, 1.5V batteries.
 |
‘Battery OK’: measurements are possible |
 |
‘Battery Low’: battery needs to be replaced and measurements are still possible |
 |
‘Battery Exhausted’: measurements are not possible |
Note: It is important to turn the instrument off before replacing the battery otherwise the thermometer may malfunction.
