Acidimeter calibrator's batch examination controlling means

Acidimeter calibrator's batch examination controlling means belongs to measurement detection area, the utility model discloses a solve the problem of traditional acidimeter examination inefficiency. The utility model discloses the scheme: the transfinite reference voltage input of alarm unit of a n acidimeter is connected simultaneously to acidimeter calibrator's standard current potential output current potential command input end and a n error, the transfinite detection data input end of alarm unit of an error is connected to the indicating value of every acidimeter output as a result, transfinite alarm unit basis of error it monitors the acidimeter and whether has indication error and transfinite to detect data and reference voltage, the error transfinites, and A1 is put including transporting to the alarm unit, A2, resistance R1~R6, slide rheostat RP1~RP2, diode VD1~VD2, NPN triode VT1~VT6, upper limit pilot lamp LED1, lower limit pilot lamp LED2, upper limit alarm loudspeaker BL1 and lower limit warning
