Portable ph meter millivoltmeter pH-420

pH-420 is a new generation of professional pH meters, which is a continuation of the pH-410 series of pH meters with new functionality that until recently could only have been available in expensive stationary devices from large foreign manufacturers. The use of modern technologies has made it possible to significantly reduce the cost of pH meters and improve technical, operational and metrological characteristics. The pH meter has no domestic analogues both in terms of technical capabilities and in terms of price / quality ratio. Lightness, simplicity, reliability and ease of use allow to quickly and efficiently measure the activity of hydrogen ions (pH), redox potential (Eh) and temperature in solutions, drinking water, food products and raw materials, environmental objects and production control systems of technological processes.pH-meter pH-420 can be used in industrial, clinical diagnostic, forensic, research laboratories; stationary and mobile, including field ones, control bodies, inspection and supervision, workshops of universities. Main features of the pH meter Large and contrast liquid crystal indicator. Convenient functional keyboard. Automatic temperature compensation of the pH meter, simplified input of the coordinates of the isopotential point. Simultaneous display of values on the indicator. pH, mV, temperatures. Power supply of the pH meter from a 220 V electrical network or built-in battery with automatic recharge. Convenient and quick calibration of the pH meter: the pH values of standard buffer solutions have already been entered into the memory of the device, at the end of the calibration process the indicator shows the slope value Electrode hydrogen characteristic Automatic buffer recognition Battery discharge indicator Compatibility of the pH meter with electrodes of most domestic and foreign manufacturers (BNC connector), including combined ones Standard delivery set of the pH meter: Measuring transducer adapter for 220VCombined pH-electrodeStandard-titersAdditional delivery: pH-electrodes for various purposesMagnetic stirrerLaboratory standSpecialized pH-electrodes: Model.
