> Cal-Check detects contaminated buffer

Revolutionary microprocessor pH/temperature meter automatically warns user of a dirty electrode or contaminated calibration buffer solution. Even the slightest amount of sample residue left on an electrode can alter the pH reading by 0.1 of a pH unit. Cal-Check also displays condition of electrode each time a calibration is performed. Improves laboratory efficiency and productivity by eliminating costly errors. Additional features include: automatic and manual temperature compensation; up to 500 log points;FS232 port , seven memorized calibration buffers; measures pH/ORP/temperature. Supplied compelete with combination pH electrode, stainless steel temperature probe, electrode holder, cable, calibration buffers and electrolyte solution. Dimensions: 9" x 7" x 3"H. Weight: 2 lbs. Electrical Req.; 120VAC, 60Hz.
