SR723 pH/ mV/ Conductivity/ TDS/ Sal./ Res./ Temp. 7-in-1 Meter Technical parameter

Extech EC600 is OEM made based on ours this meter SR723. They use totally same IC borard and shell, and technology to produce. Prominent Features -Double parameters meter, with pH electrode, conductivity electrode, and with calibration solution and special carrying case, easy to use. -Built-in microprocessor chip, with the intelligent functions of automatic calibration, automatic temperature compensation, data storage, function setting and automatic self-diagnose, auto power off and low voltage display etc. -Adopts digital filter and step slipping technology to intelligently improve meter' s response speed and result accuracy. " " will appear when reading to be stable. -Automatically recognize 13 kinds of pH standard buffer solution. User can choose anyone from three series of buffer solutions: Europe & U.S.A. series, NIST series, China series. -High purified water and ammonia added purified water pH measuring mode can be set up, for this two special pH measuring modes, besides the general slope temperature compensation, also added function of nonlinearity solution temperature compensation to make measurement more accurate, especially suitable for the fields of electric power and petrochemical etc. -Adopts advanced automatic frequency convertible and voltage regulation technology to enlarge the measuring range of conductivity electrode which constant K= 1 to 10 times. It can meet measuring accuracy requirement for range within 0 to 200mS/ cm by using only one-point calibration. It is the particular one– point calibration function for this meter. -Automatically recognize 8 kinds of conductivity standard solution. User can choose anyone from two series of standard solutions: Europe & USA series and CHINA series. -Automatically select conductivity measuring range, the meter will do non-linearity temperature compensation test for purified and high purified water less than 10uS/ cm, which greatly improve the measuring accuracy. It is especially suitable for use in fields of electric power, microelectronics and medicine. -Meter' s circuit board adopts SMT film-covering technology to improve meter' s production reliability. -Meter has the back light LCD display monitor. 1-Dustproof and waterproof meter meets IP57 rating. 1. pH: Measuring range ( -2.00 to 19.99) pH Resolution 0.1/ 0.01 pH Accuracy Meter: ± 0.01pH; connect meter with electrode: ± 0.02pH Temp.
