Introduction

UT377C is a Moisture Meter measured in contact or induction way, testing the moisture content without damaging the wood and building materials, with features of high accuracy, reliable performance, undamaged measurement, etc. It is widely used in the industries of manufacturing, wood processing, architectural decoration, scientific research, quality control, etc.

Features

1. Undamaged measurement on the surface of wood and building materials.
2. Fast measurement without drying and humidification for the wood or building materials.
3. With a high-accuracy sensor, features of high accuracy, wear resistance, and stability.
4. The wood grain direction does not affect the moisture content measurement.
5. The grip has little effect on the moisture content measurement.
6. Measurement depth is up to 30mm.
7. Three lights in green, yellow and red.
8. Audible alarm.
9. Flashlight.
10. Color screen LCD & More visual measurement.

Configurations

Take the meter out of the package to check if the device or any components are missing or damaged.

Safety

Please read the Safety carefully and follow these steps.

1. Avoid any metals existing below the probe during the measurement.
2. Do not press the meter hard or drag it to avoid the sensor surface wear.
3. Do not use anything sharp to scratch the sensor to avoid any sensor surface damage.
4. Keep the sensor in a clean condition to avoid dust and oil pollution.
5. Do not store or use the meter in high temperature, high humidity, flammable, explosive or strong electromagnetic environments.
6. Do not dismantle or assemble randomly to avoid damage.
7. Replace the battery in time when the low battery shows, and take the battery out if it is not used for a long time.
8. The battery is the standard AAA Alkaline Battery, which cannot be charged.
9. Maintenance: Please use a soft cloth and neutral detergent to clean the case. Do not use abrasives or solvents.

Operations

Power On/Off

1. Power On : Long press POWER button until the screen is on.
2. Power Off : Long press POWER button until the “OFF” shows on the screen.

Measurement

1. Check the type of measured target, Softwood, Hardwood, Drywall or Masonry, then short press the MODE button to select.
2. Place the sensor (back side of the device) on the measured target, measuring the moisture content.

Notes

• Place the sensor (back side of the device) on the measured target to keep in good touch with each other for high accuracy. Meanwhile, measure the target as per the following handhold way, only using fingers to hold the device, with palm away from the device to avoid the reading error.
• Make sure the surface of measured target is free of dust and dirt during the measurement.
• Repeatedly measure the target to get the average value of moisture content due to its uneven moisture distribution.
• Avoid nails or others sharp during the measurement of when the device is slid on the surface of measured target checking the moisture content quickly.
• At least 25mm is gapped below the measured target. Make sure your hands are not below the device during the measurement.
• The measured target should be in the range of sensor area for accurate reading of moisture content due to the size of sensor (50mm*50mm).
• Wipe the extra moisture existed on the surface of measured target and dry the surface for a few minutes before the measurement.
• Do not measure the target with open defect or in any irregular position.
• Drywall and Masonry measurement of device is to get the relative value, which can quickly compares different moisture content of building materials to locate the high/low moisture area. The moisture location also can be judged by the moisture content requirements, to see if the place reaches to the acceptable moisture content. The reading range of two modes is within 0~99.9%.
• Please stack the measured target before the measurement when its thickness is <6mm, because the minimum thickness measured is 6mm.
• The device enters the power-saving mode in the 30s and the LCD backlight turns dark when there is no action on the device or it stops measuring. Short press the button or continue to measure, and the LCD backlight will return to the original status.

Zero Reset

Reset to zero if the moisture content is >0.0% shown in the LCD when picking up the device. See the following steps:

1. Pick up the device and let it in the air to keep the sensor away from the measured target.
2. Long press button, showing “ZERO” in the LCD, resetting to zero.
3. The “ZERO” indication will disappear in 2s, finishing the operation.

Notes

• For furniture, the moisture content is 5%~6% in the low relative moisture area, 10%~11% is acceptable in the high relative moisture area.
• For indoor wood, the moisture content is 6% in the low moisture area, 12% in the high moisture area.
• For outdoor wood, the moisture content is 10%~15%, which depends on the local moisture condition.
• More than 18%~20% moisture content of wood can be provided for the termites and wood wood-boring insects living. Meanwhile, high moisture content is also supported for the mycoses and biological growth.
• When the moisture content of wood is over 28%, it reaches to the fibre saturation point.

Audible Alarm

• Buzzer alarms when the moisture value is >24% in the wood test.
• Buzzer alarms when the relative value is > 60% in the building materials test.
