Hash portable dissolved oxygen analyzer HQ1130

Hash portable dissolved oxygen analyzer HQ1130It was before 2021Hash dissolved oxygen analyzer HQ30DUpgraded version. The upgraded dissolved oxygen analyzer is more portable and comfortable to operate. When the blue light emitted by the LED light source shines on the fluorescent substance on the surface of the dissolved oxygen meter sensor, the fluorescent substance is excited and releases red light. The higher the concentration of dissolved oxygen, the shorter the time from emitting blue light to releasing red light. The dissolved oxygen meter will record this time and establish a correlation between the red light release time and the dissolved oxygen concentration, LDO ™ The dissolved oxygen meter calculates the dissolved oxygen concentration by measuring the release time of red light and directly displays the result on the screen.

Hash portable dissolved oxygen analyzer HQ1130Suitable for drinking water, sewage, food and beverage, industrial water, electricity, surface water, laboratory and field testing.

1) No polarization required: LDO ™ The dissolved oxygen analyzer probe does not require polarization.

2）No calibration required:LDO™ The dissolved oxygen analyzer probe has been calibrated before leaving the factory

3）Strong anti-interference ability: The probe is a membraneless probe, so it is not affected by chemical substances in wastewater, and the measurement results are more accurate.

4）Low maintenance volume:LDO™ The portable dissolved oxygen analyzer does not require replacement of membrane components or filling of electrolyte, with low maintenance, saving time and reducing maintenance costs.

5）Durable fluorescent cap: The fluorescent cap of the dissolved oxygen meter probe can maintain its accuracy even when scratched or partially contaminated, making it easy to clean.
