Analytical Instruments Co., Ltd. Shanghai Jinpeng excellent chemical and biological laboratory equipment and foreign manufacturing experience exclusively produced PHB-5-type PH meter portable laboratory, to conduct systematic Xiangjie to quickly check the latest products, quotes, pictures, technical parameters, or for product performance comparison, very convenient to use
PHB-5 Portable PH Meter
First, performance characteristics:
PHB-5 Portable PH meter is a digital display pH meter, which uses a blue backlight, two-row LCD digital display can simultaneously display pH, temperature, or potential (mV) values. The instrument applies to universities, research institutes, environmental monitoring, industrial and mining enterprises and other departments of the laboratory sample determined aqueous solution pH value and potential (mV) values, coupled with ORP electrode measurable solution ORP (oxidation - reduction potential) value , coupled with ion-selective electrode can measure the value of electrode potential of the electrode.
