UNI-20 Universal Transmitter has strong universality and can be connected freely to all digital sensors and analog sensors that researched and produced by Probest company.The measured parameters includes pH, DO, ORP, conductivity, turbidity, SS,chlorophyll, blue-green algae, residual chlorine and etc.Meanwhile,UNI-20 can set single channel or dual channel configuration upon request.A transmitter can connect two sensors at the same time to reduce the cost of transmitter and installation space.

PPH-500 pH sensor is a combination electrode combined precious metals indicator electrode with reference electrode. Firstly measure the potential difference of working battery made up of measuring electrode and reference electrode in the solution,then use linear relation of pH value of the measuring solution and potential of working battery to realize the on-line monitoring.

POP-500 ORP sensor is a combination electrode combined precious metals indicator electrode with reference electrode. Firstly measure the potential difference of working battery made up of measuring electrode and reference electrode in the solution,then use linear relation of ORP value of the measuring solution and potential of working battery to realize the ORP on-line monitoring.

Conductivity sensor is a kind of glass platinum electrode.Its principle is putting 2 conductance pieces in which a voltage is added into the sample solution to measure current in the solution.Then calculate the conductivity by voltage and current.

PFDO-700 Fluorescence optical DO sensor Dissolved Oxygen meter Online water analysis. PFDO-700 Dissolved Oxygen analyzer adopts fluorescence method to measure dissolved oxygen.The cap of the sensor is coated with a luminescent material. Blue light from an LED illuminates the luminescent chemical. The luminescent chemical instantly becomes excited and releases red light. The time and intensity of red light are inversely proportional to the concentration of oxygen molecules, So the concentration of oxygen molecules is calculated.

PSS-800 SS TSS MLSS Sludge Concentration sensor On-line Analyzer water quality tester. PSS-800 SS(Sludge Concentration )Sensor is based on the method of combination of infrared absorption scattered light.Infrared light which the photosource sends out scattered by suspended particles in the sample.And finally  converted to electrical signals by photoelectric detector and getting the suspended solids concentration of the sample after treatment by analog and digital signals.

CL-201 adopts DPD colorimetric method to measure concentration of residual chloride.The analyzer has high accuracy,high cost performance and low maintenance.Widely used in residual chloride measurement of drinking water pipe network and chlorination process.Continue running for 30 days without replacing reagent.Unattended operation,low operation and maintenance cost.
