Lead exposure can cause serious health problems, especially in young children. When lead is absorbed into the body, it can cause damage to the brain and other vital organs. The greatest concern is even exposure to “low level” lead reduces a child's ability to learn. Our cutting-edge Lead tests are quick, accurate and easy to operate in the field.

Main Specifications: Measuring range (Range): 0.00-14.00PH Accuracy (Accuracy): ± 0.1PH Operating voltage: 3 * 1 .5V Operating temperature: 0-60 degrees Resolution (Resolution): 0.1PH Size (Size): 150mm (L) × 27mm (W) × 15mm (H) PH meter calibration: 1. the pH electrode at 6.86 (25 ℃ immersed in a pH, the standard mixed phosphate buffer solution, and gently shaken. 2. with a small screwdriver to adjust the calibration potentiometer until the display value and standard buffer solution at ambient temperature ph value match. 3. the electrode into phosphorus potassium pH4.00 stupid acid or borax pH9.18 standard buffer solution. 4. after about two minutes or so. The pH value of the buffer solution is displayed shall be compared to the range of allowable error. Note: In the following cases, PH meter must be recalibrated: After calibration has been used (or place) for a long time; Frequent use of special electrodes; Accuracy requirements are relatively high. Steps: 1. Remove the protective cover. 2. first with distilled water pH meter electrodes. And the electrode dry with filter paper. 3. turn the switch located on the battery compartment. 4. the pH meter is inserted measured liquid, until the liquid immersed ""immersion line"", conditions permitting, the solution can be dipped slightly ""immersion line"" position. 5. Gently stir the solution and wait for about two minutes Chung. Read the display. 6. after use. Clean the electrode. Turn off the switch. Wear a protective sleeve. Meter calibrator: i.e. pH standard solid material. Can be used to open the package after adding water. Applies to any type pH meter calibration.
