ph conductivity double-parameter measurement meter which is suitalbe for general measurement in laboratory. it is suitable for measuring the ph value of moderate ionic strength aqueous solution, and conductivity values of conventional solution
|
● the most widely used ph conductivity double-parameter measurement meter. |
| ●meter meets with the requirement of international glp standards. its features up to automatic calibration, automatic temperature compensation, data storage, timing measurement, clock display, rs-232 output, function setting and self-diagnose etc. |
| ● there are three different measurement modes: stable display mode; time measurement mode; continuous measurement mode. |
| ● automatically recognize ph buffer solution. user can choose anyone from three series of standard buffer solutions: europe & usa series, nist series and china series. |
| ●adopt advanced and original conductivity measurement technology, use 1 pc of conductivity electrode (k=1), it can meet measuring accuracy requirement for range within 0.5μs/cm ~ 200ms/cm by using only one-point calibration. |
| ● can switch conductivity, tds, salinity and resistivity. |
| ● meter has the only product serial number. |
| ● dustproof and waterproof meter meets ip54 standards. all sockets are seal protected by the silica gel caps. |
