Madgetech Data Recorder for Measuring pH Levels and Temperature


  • Measure and Record pH and Temperature Levels Using External Sensors (Sold Separately)
  • pH and ORP Electrodes are Connected Directly with BNC Connector
  • -2.0 to 16pH and -40°C to 110°C Measurement Ranges
  • 2 Second to 24 Hour User-Selectable Sampling Rate (Configured in Software)
  • User Replaceable 9 Volt Lithium or Alkaline Battery with 1 Year Life (Included)


pH/ORP/ISE Measurement Range: -2.0 to 16.0 pH
Accuracy (Calibrated): ±0.01 pH
Resolution: 0.01 pH
Input Connection: Female BNC Jack
Input Impedance: 1012Ω Typical
pH EMI Susceptability: < 0.2pH @ 3V/M, 80MHz to 1GHz 
ORP/ISE Accuracy: ±0.1 mV 
ORP/ISE EMI Susceptability: < 10mV @ 3V/M, 80MHz to 1GHz
ORP/ISE Measurement Range: ±1.25 Volts
Temperature Measurement Range: -40°C to 110°C (80 to 145 Ω)
Accuracy (Calibrated): ±0.15°C @ 25°C Ambient (±0.015Ω)
Resolution: 0.01°C (0.001Ω)
