MEASUREMENT OF FREE /TOTAL CHLORINE:
Photometric measuring principle, colorimetric method with DPD. High-precision automatic chemical supply system for measuring with peristaltic pumps (1 or 2 channels). LED emitter at 520 nm, silicon photosensor. Measurement range: 0 - 5 ppm (mg /l). Resolution: ± 0.01 ppm. Accuracy: ± 2% of measured value, 98% repeatability. The frequency of control measurements is programmable from 3 to 120 minutes, in one minute increments. Step-by-step signaling of the lack of reagents (refilling): preliminary warning and complete blocking of work.
TEMPERATURE MEASUREMENT:
Thermal resistive measurement method. Sensor type NTC 100K at 25 ° C. Measurement range 0 - 50 ° C. Resolution ± 0.1 ° C. Accuracy ± 0.2 ° C, 99% repeatability.
PH LEVEL MEASUREMENT:
Potentiometric measuring principle. Measurement range: 0-14 pH. Resolution: ± 0.01 pH. Accuracy: ± 1% of measured value, repeatability 98%. Asymmetry correction from 45 to 70 mV /pH. Input impedance 10 GΩ. Bias current
REDOX MEASUREMENT (ORP):
Potentiometric measuring principle. Measurement range: –1500 +1500 mV. Resolution: ± 1 mV. Accuracy ± 1% of measured value, repeatability 98%. Input impedance 10 GΩ. Bias current
