Máy đo PH 766 phòng thí nghiệm - Knick Việt Nam

Equipment Meter with power cord, without electrode

Ranges pH: –2.00 ... +16.00 / mV: –1999 ... +1999 / ºC: –50.0 ... +150.0 Display Alphanumeric 2 x 4 digits, 14-segment LED, character height 13 mm; Measurement symbols pH/mV/ºC/man, 3 Sensoface icons inform on the condition of electrode and measuring equipment (GLP

Measuring cycle Approx. 1.5/

Accuracy!} pH: <0.01 / mV: ><0.1 % ±0.3 mV / ºC: ><0.3 K 

Input DIN 19262 

Input resistance >1 x 10!‡ Ohm

Input current (20 ºC)‡} < 1 x 10–!‡ A

Temperature coefficient <0.1 count/K 

Electrode standardization Calimatic automatic calibration and buffer recognition (German patent 29 37 227), For buffer sets, see Page 76, permitted calibration ranges: Zero: pH 6 … 8 Slope: 47 ... 61 mV/pH (25 ºC)

Electrode monitoring Sensoface evaluates zero, slope, response time, and glass impedance of the electrode, electrode condition displayed as good / average / poor, can be disabled 

Device self-test Gaincheck Displays all Sensoface criteria and electrode data, tests measurement electronics including memories, measured value processing, and recorder output, checks display and keypad during diagnostics, automatic short check at power-on 

Temperature compensation Pt 1000, automatic selection Manual: 0.0 ... +100.0 ºC*}

Recorder output*} Trueline pH-compensated, no quantizing levels mV: 1 mV/mV pH: 100 mV/pH Automatic matching to measured value setting 

Calibration data storage Automatic storage of calibration data and settings, self-contained

Data retention >10 years (EEPROM)

Recorder output*} Galvanically isolated mV: 1 mV/mV / pH: 100 mV/pH / ºC: 10 mV/ºC
