เครื่องวัดกรดด่าง เครื่องวัดค่า pH Meter Auto Calibration °C/ °F วัดอุณหภูมิ และ กันน้ำได้ รุ่น 8681

>> เช็คสต๊อคสินค้า <<

PH868-1 is designed to measure pH levels from 0~14 and has the following advance features: automatic calibration (ph4.0, pH7.0 & pH10.0), with high ingress protection rating - IP67 - 100% waterproof & dustproof, automatic temperature compensation (ATC), dual display (pH & temp), switchable °C & °F, data hold, low battery indicator, and auto power off that can be disable.

PH868-1 has also a built-in ATC to ensure 100% accuracy. Even the slightest change in temperature affects the accuracy of reading results; ATC lets the meter adjust or adopts current temperature of the environment without shifting or restarting the meter. PH868-1 is totally protected against dust & effects of immersion between .15m and 1m. It has a high Ingress Protection Ratings of IP67. An IP number is used to specify the environmental protection of enclosures around electronic equipment and was developed by the European Committee for Electro Technical Standardization. These ratings are determined by specific tests. It is composed of 2-3 numbers, the first referring to the protection from solid objects or materials (with 1-6 level), the second against liquids or water (with 1-8 levels) and the third against mechanical impacts. Higher IP number means better the protection.
