Description
Portable pH meter pH meter - ATC with temperature compensation - red
Configuration: detection pen * 1 correction powder * 2 instructions * 1 small screwdriver * 1 plastic box packaging * 1
Weight: the net weight of the test pen is about 54G, and the packaging with plastic box is about 112G
Power supply: built in 1.5V button battery * 3
Measurement range: 0.00-14.0ph
Resolution: 0.01 pH; Accuracy: ± 0.01ph
(ATC) automatic temperature compensation: 0 ℃ - 55 ℃
Service environment: it is recommended that 0 ~ 50 ℃ RH ＜ 95%
Scope of application: water purifier, domestic water, tap water, food, aquatic fish tank, cosmetics, industrial sewage, ocean, laboratory and other fields.(Related knowledge: According to the published results of the pH test values of various cosmetics, the pH value is also one of the standards for distinguishing the authenticity of cosmetics. If the pH value is not within the normal range, it indicates that it has deteriorated and cannot be used.)
1. Mix a pack of 6.86 calibration powder with 250ML of water (distilled water/purified water/neutral pH water, room temperature) and gently shake. Put the pen down to test the pH value of the solution. If it shows 6.8, the pen is accurate.
2. If the display deviates from 6.8, use a small screwdriver to adjust the calibration potentiometer (small hole behind) until the displayed value matches the pH value of the standard buffer solution at ambient temperature. When calibrating with 4.0 correction powder, simply adjust the pen to 4.0. Do not leave the detection pen off the water surface during calibration
