C821-MDA-PH

PH and ORP / Redox Transmitter and Controller

Function: PH & ORP / Redox Transmitters and Controller

PH Measurement Range: 0.00 ÷ 14.00 pH

ORP / Redox Measurement Range: -2000 ÷ +2000 mV

AO Output: 4 ÷ 20 mA Isolated - Configurable

Communication: RS485 ModBUS RTU Isolated

DO Output: 2 Dry Relay Contacts (3A/250Vac) - Configurable

Power Supply: AC (220Vac ±10%) - (110Vac ±10%) / DC (24Vdc ±10%)

Power Consumption: 6W

Resolution: PH (0.01 PH) - ORP / Redox (1 mV)

Accuracy: PH (±0.02pH) - ORP / Redox (-2000 to -1000 mV = ±2mV) (-1000 to +1000 mV = ±1mV) (+1000 to +2000 mV = ±2mV)

Repeatability: 0.02pH

Temperature Compensation: Manual & Automatic (-10 to +130℃) with sensors:

- NTC10K = (-10 to +60℃) accuracy ±0.3°C / (+60 to +130℃) accuracy ±2°C

- PT1000 = accuracy ±0.3°C

- PT100 = accuracy ±0.3°C
