The principle of pH meter To measure the pH value with a pH meter, insert a pair of working electrodes into the solution to be tested, one is a reference electrode with a known and stable electrode potential (usually a calomel electrode), and the other is a electrode whose potential varies...
PH meter, electric device used to measure hydrogen-ion activity (acidity or alkalinity) in solution. Fundamentally, a pH meter consists of a voltmeter attached to a pH-responsive electrode and a reference (unvarying) electrode. The pH-responsive electrod
Dosing process of manual operation, also can through the PC machine, magnetic level gauge, pH meter, stroke controller, inverter and other electrical, instrumentation, the dosing device become automatic control of mechatronic products, achieve. According to the need of industrial process, the appropria...
When the Spectrometer Nitrate sensor is working, the water sample flows through the slit. When the light from the light source in the sensor passes through the slit, part of the light is absorbed by the sample flowing in the slit, and the other light pass...

Plastic cuvettesare cheaper, easily scratched, and have shorter lifespans. Photocell (Photodetector): These photosensitive devices measure light intensity by converting light energy into electrical energy. Galvanometer:The electrical signal generated in a photocell is detected and measured by a galvanomet...
N2is preferable when a large consumption of carrier gas is employed. Carrier gas from the tank passes through a toggle valve, a flow meter, (1-1000 ml/min), capillary restrictors, and a pressure gauge (1-4 atm). Flow rate is adjusted by means of a needle valve mounted on the base ...
Molecular weights of compounds can be measured spectrophotometrically by preparing the suitable derivatives of these compounds. UV spectrophotometer may be used as a detector forHPLC.
