PHS-W series of microprocessor-based pH / mV meter 
 PHS-W series of microprocessor-based pH / mV meter contains 25CW, 3CW, 3BW three 
 Models, instruments for measuring liquid pH value and electrode potential (mV). . 
 Two points automatic calibration button: 
 PHS-W Series has a key two points calibration, the calibration, the instrument automatically 
 Tips you need to use the standard buffer type, you simply follow the prompts, the 
 Electrode sensor immersed in the corresponding calibration solution, according to ENTER key, the instrument that 
 Automatically calibrated. . 
 Auto-ID standard buffer solution: 
 Calibration, if you mistakenly use a standard buffer or standard deterioration 
 Standard buffer, the instrument will automatically prompt the error and stop the calibration procedure. 
 PHS-W series has this feature to avoid user errors using the standard 
 Metamorphic buffer or calibration solution using the calibration error caused. . 
 Automatic electrode slope and status display: 
 Calibration is completed, the instrument automatically displays the electrode slope value, if the electrode sensor 
 Had expired, the screen icon will automatically within the electrodes off. 
 Automatic temperature compensation and measurement: 
 3BW-type with a temperature probe, real-time temperature measurement of liquid, such as 
 If used in conjunction with the pH electrode, the instrument will be transferred to automatic temperature compensation mode. . 
 Optional standard buffer type: 
 PHS-W series standards with NIST and the USA group buffer, you can 
 Select the country where one group of standards calibrated instruments. . 
 Custom LCD display: 
 Instrument uses custom LCD display, simple and bright, not only to clear the screen 
 Xi display of measured values, but also with operational mode icon, so you head out for a 
 In relation to the understanding of the operational status of equipment. . 
 Waterproof keyboard and electrode holder: 
 PHS-W series assembly waterproof panel, acid, you do not have to worry about spill samples 
 Damaged equipment on the instrument falls, flexibility of the electrode holder to stop the release, 
 Very convenient to use. .
