Note:
Sensors to avoid contact with solvents (including silica gel and other adhesive) high concentrations,
coating, pharmaceutical, oil and gas;
Gas ventilation face don't congestion, pollution, pore clogging is sometimes the cause of low sensitivity; Sensor internal use of disposable packaging, please don't open the sensor; Save the sensor electrode should be in short circuit condition;
Before using the sensor must be aged not less than 24 hours, 48 hours is better!
If is used for sensor problems on any questions, please consult the manufacturer's technical service
department in order to correctly use sensors. Provide professional technical support!
