RK500-12 Liquid PH Sensor Water Quality Monitoring Sensor
PRODUCT DESCRIPTION
Turbidity sensor is an instrument which uses optical principle to measure the degree of turbidity of water. Turbidity is caused by suspended particles in water. The suspended particles reflect the incident light. Usually, the scattered light in the direction of 90°is used as the test signal, so the unit tested is called NTU. This method is suitable for testing low to medium range, ranging from 0.01 to 4000FNU. According to EN27027 and ISO7027 standards, infrared light of 860 nm is used as light source, which can not be disturbed by the chromaticity of samples.
RK500-11 Liquid Temperature Sensor is used to measure the temperature of the liquid medium, applied to the automatic meteorological station, pond or reservoir water temperature detection and other fields.Sensor with precision thermal resistance as a sensing component, built-in signal sampling and amplification, zero drift and temperature compensation function, has the characteristics of high measuring precision and good stability.
RK500-12 ORP sensor is simple and cost effective solution for a wide variety of waste water and process applications. This all-in-one sensor provides simultaneous measurement of ORP and temperature. The rugged Ryton body is designed for easy installation into on-line via the 3/4 inch tapered threaded connections provided on both ends of the sensor. The wide body sensors (26 mm diameter) hold four separate elements in one unbreakable Ryton body, large volume gelled electrolyte and the double junction reference system slows down depletion and poisoning extending the life time.
High precision.
High sensitivity.
Fast response.
Widely used.
Excellent stability.
Simple operation.

ELECTRODE MAINTENANCE & INSTALLATION AND FIXED
PH electrode is not used at ordinary times and can be soaked in 3mol/l KCL solution or saturated KCL solution. It is strictly prohibited to immerse the electrode in distilled water and deionize the water or tap water with minimal plasma content.If the PH electrode is contaminated with inorganic substances, it can be cleaned with 0.1mol/l Hcl or NaOH solution for a few minutes and then washed with distilled water. If the PH electrode is contaminated with organic substances, it can be cleaned with alcohol or acetone and then cleaned with distilled water.(note: the protective cap before the electrode should be removed when using);
Clean the electrode with tap water every 3 months or 6 months according to the working environment.
Mounting bracket(length=1m) is optional
