APX1 pH/ORP Controller (Analog output, RS485)

Main test object: pH or ORP
Measuring principle:
pH: Glass pH electrode (hydrogen ion concentration index)
ORP: platinum or gold electrode (oxidation reduction potential)
Measuring range/resolution:
pH: 0~14pH / pH: 0.01pH
ORP: ±2000mV / ORP: 1mV
Temperature: -20~150°C / Temperature: 0.1°C
Temperature compensation: Manual/automatic selection
Accuracy: 0.1% of the measuring range (PH: ±0.02pH, ORP: ±2mV), whichever is greater
Stability: 0.05% of measuring range per 24 hours, no accumulation Repeatability: better than 0.1% of the measuring range
Display screen: 3.2-inch LCD display
Instrument operation: PET button panel with 4 buttons
Calibration method:
pH: 3 points, double slope calibration, calibration points can be set freely; ORP: 2-point calibration
On-site comparison for offset correction calibration
Power-off protection: the instrument is powered off, and the set data is permanently retained
