This series of instrument is a kind of used to test and control PH value of the precision instrument. A built-in miniature computer storage, calculation and compensation relevant measurement PH value of all parameters, such as PH value display, temperature display, temperature compensation, high alarm value display and so on. Inbuilt EPROM make this series of instrument can in AC power supply cut off or power supply line fault still can save the correction and set point value./
This series of instrument of a characteristic is that it can controller online correction. Other additional device and characteristics, such as isolation type 4 ~ 20 ma output current (optional), easy reading screen also showed more parameters and 30 days data query display function (optional), 485 communication interface (optional). Simplified operation convenient, make series instrument become industrial test and control PH value of the ideal instrument./
Technical performance/ Measuring range: pH: 0.00 ~ 14.00 pH; Resolution: 0.01 pH; Level : 0.05 magnitude; Stability:/ acuities were 0.03 pH / 24 h;/ Calibration adjustable scope: zero + / - 1.45 Ph slope 80% ~ 100%;/ PH standard liquid: 6.86/4.01/9.18; . 00/7.00/10.01; Control range: 0 ~ 14.00 pH/ Temperature compensation: 0 ~ 60C , signal output: 4 ~ 20 ma/ Control interface: ON/OFF relay contact/ Electrical bear load: MAX 220 vac / 12 VDC 2A; MAX 125 vac / 28 VDC 5 a/
Signal output load: acuities 500 ?; Signal input impedance: or 1 x 10,000000000000 ?/ Main function configuration/ Has the display, high and low point output ON/OFF, high and low point alarm, 30 days historical data query (optional), 4 ~ 20 ma current output (optional), 485 communication interface (optional)./ Temperature compensation/
Series PH meter with automatic temperature compensation function, if temperature on PH value influence is not big don't pick removing instrument default and display 25C./ Signal output/ 4 ~ 20 ma current output, the output load is less than 500 w. 4-20 ma corresponding PH value 0-14. Installation steps/ In any piece of thickness of 1/16 inch (1.5 mm) to 3/8 inch (9.5 mm) panel, prescribing a rectangular incision. The size of holes for 92 x 92/
