wintact WT323E Infrared Thermometer

Product Information

The WT323E Infrared Thermometer is a device that is used for measuring the temperature of an object’s surface. It is designed to measure various hot, hazardous or hard-to-reach objects without contact, safely and quickly. The unit consists of Optics,Temperature Sensor Signal amplifier, a Processing circuit, and LCD Display. The Optics collects the infrared energy emitted by the object and focuses it onto the Sensor. The sensor translates the energy into an electricity signal. This signal will be turned out to be digital shown on the LCD after the signal amplifier and processing circuit. The Distance to Spot size of the unit is 16:1. The smaller the target, the closer the measure distance. When accuracy is critical, make sure the target is at least twice as large as the spot size. The unit has an emissivity of 0.95 (preset in the unit) for most organic materials and painted or oxidized surfaces. Inaccurate readings will result from measuring shiny or polished metal surfaces. To compensate for this, adjust the unit’s emissivity reading or cover the surface to be measured with masking tape or flat black paint.

Product Usage Instructions

Before using the WT323E Infrared Thermometer, please read through the following instructions to ensure proper usage:

1. Open the battery door and load two 1.5V AAA batteries.
2. Pull the trigger to turn on the unit.
3. Aim at the target surface and pull the trigger, the temperature will be shown on the LCD. This unit is equipped with a laser, which is only used for aiming.
4. When taking measurements, pay attention to the Distance to Spot Size. As the Distance (D) from the target surface increases, the spot size (S) of the area measured by the unit becomes larger.
5. Make sure the target is larger than the unit’s spot size. When accuracy is critical, make sure the target is at least twice as large as the spot size.
6. To find a hot spot, aim the thermometer outside of interest, then scan across with an up-and-down motion until you locate the hot spot.

Introduction

This infrared thermometer is used for measuring the temperature of the object’s surface, which is applicable for various hot, hazardous or hard- toreach objects without contact safely and quickly. This unit consist of Optics, Temperature Sensor Signal amplifier, Processing circuit and LCD Display. The Optics collected the infrared energy emitted by object and focus onto the Sensor. Then the sensor translates the energy into an electricity signal. This signal will be turned out to be digital shown on the LCD after the signal amplifier and processing circuit.

WARNING & CAUTIONS

Warning:
To avoid the potential situation may cause harm or damage to people, please pay attention to the following items:

1. Do not point laser directly at eye or indirectly off reflective surfaces.
2. The unit cannot measure through transparent surfaces such as glass or plastic. It will measure the surface temperature of these materials instead.
3. Steam, dust, smoke, or other particles can prevent accurate measurement by obstructing by the unit’s optics.

Cautions
The infrared thermometer should be protected for the following:

1. EMF (electromagnetic fields) from arc welders, and induction heaters.
2. Thermal shock (cause by large or abrupt ambient temperature changes allow 30 minutes for unit to stabilize before use).
3. Do not leave the unit on or near objects of high temperature.

Distance to spot size

1. When take measurement, pay attention to the Distance to Spot Size. As the Distance (D) from the target surface increases, the spot size (S) of the area measured by theunit becomes larger. The Distance to Spot size of the unit is 16:1.(Figure 1)
2. Field of view: Make sure the target is larger than the unit’s spot size. The smaller the target the closer measure distance. When accuracy is critical, make sure the target is at least twice as large as the spot size.

EMISSIVITY

Emissivity: Most organic materials and painted or oxidized surfaces have an emissivity of 0.95(preset in the unit). Inaccurate readings will result from measuring shiny or polished metal surfaces. To compensate for this, adjust the units emissivity reading or cover the surface to be measured with masking tape or flat black paint. Measure the tape or painted surface when the tape or painted reach the same temperature as the material underneath.

Operation

Operating the unit：

1. Open battery door and load two 1.5V AAA batteries.
2. Pull the trigger to turn on the unit.
3. Aim at the target surface and pull the trigger, then temperature will be shown on the LCD. This unit is equipped with a laser, which is only used for aiming.

Locating a Hot Spot：
To find a hot spot, aim the thermometer outside of interest, then scan across with an up and down motion until you locate the hot spot. (Figure 2).

LCD display & buttons

• Temperature measurement units
• K-type thermocouple
• Data reading indicator
• Emissivity
• Data holding indicator
• Low power indicator
• Ambient temperature value
• Ambient humidity value
• Dew point temperature value

Names and functions of parts: as shown in Figure 4

1. Measurement switch (trigger).
   Pull trigger to display temperature value, and “SCAN” appears on screen at the same time; when trigger is released, temperature reading is displayed, and data is automatically maintained. The instrument automatically shut down after about 30 seconds of operation.

2. Laser switch/Down button.

3. MODE (mode switch button) / temperature unit switch button
   Press the MODE button to cycle through four modes, MODE 1→MODE 2→MODE 3→MODE

4. • Mode 1: Mildew alarm mode. Under this mode, the current ambient temperature, humidity, dew point temperature and surface temperature are displayed. Pull trigger to measure surface temperature.
     Note: The instrument decides whether the measured object is easy to mildew according to the surface temperature of the measured object and the dew point temperature of the current environment. Indicator light turns green for normal state. If the measured object tends to mildew, the indicator light turns yellow; if already mildew, the indicator light turns red.

   • Mode 2: Temperature difference alarm mode. Under this mode, pull the trigger to display the current ambient temperature and the surface temperature of the measured object. When the surface temperature of the measured object is close to ambient temperature, the indicator light turns green; if much higher than or lower than ambient temperature, the indicator light turns red. Otherwise, the indicator light turns yellow.

   • Mode 3: K-type thermocouple temperature measurement mode. Under this mode, the temperature of the K-type thermocouple is measured and the thermocouple icon is displayed. Before the measurement, insert K-type thermocouple probe into the thermocouple socket. Pull and hold the trigger, thermometer displays both surface temperature and K-type thermocouple temperature.

   • Mode 4: Emissivity setting mode. Under this mode, press up/down button to to set emissivity within the range of 0.10~1.00 by decreasing or increasing the value.

   • Temperature units switch: Pul and hold trigger, then press this button to switch units.

5. UV light button / Up button.
   Press this button to turn on/off UV light, which can be used for fluorescent leakage detection.
