Walt Mart has used the anti-mold test as one of fheir QA standands.
iHeir列表式湿度检测仪已被 Walt Mart列为最重要的品控常规检测项目之一.
My goal is to control the moisture below 12%.
the humidity below 60%.
Use the mildew tester correctly. Evaluate the moldy risk in an objective way
Precision high humidity test apparatus.
the instrument integrates measuring device, display, power supply and circuit board. Compared with similar domestic products, this instrument has the advantages of small volume, light weight, fast test speed, extremely simple operation, beautiful appearance, exquisite workmanship and easy to carry.
Directions for use
Install dry battery: connect the positive and negative poles of the battery, install the 15V dry battery into the battery box, and the positive pole is upward.
Check the instrument: use the left and right steel needles to short circuit (connected by hand or metal) and press the range switch I. At this time, a light-emitting tube below shall light up. When the left and right steel needles are open (when no conductive object is connected), press the measurement switch. At this time, the luminous tube shall not emit light. If the above requirements can be met, it means that the instrument is normal, and the test can be carried out
Measuring object: (such as measuring leather) insert the four steel needles of the tester into the material with a depth of about 6mm, press the range switch, and read the corresponding reading of the light-emitting tube of the display. If the range I switch is pressed, read the left line. If the range II switch is pressed, read the right line.
When pressing the range I switch, if the display does not emit light at all, it indicates that the reading is lower than 7%. If the display has only the lowest luminous tube emitting light, it indicates that the reading is higher than or equal to 15%. Press the range II switch and read again.
When the range II switch is pressed, if the display does not emit light at all, it indicates that the reading is lower than 16%, and it shall be read again by pressing the range I switch. If only the lowest luminous tube of the display emits light, it indicates that the reading is higher than or equal to 35%.
When the range I switch or the range II switch is pressed, if two adjacent light-emitting tubes of the display emit light, the reading can take the average value of the two digit reading, and the reading can be increased or decreased in proportion according to different brightness.
Replace the battery: if the above inspection fails to meet the requirements, the display is dim or the battery voltage is lower than 10V, replace the battery before use.
