SH-680 portable eight parameter water quality detector

This portableWater quality detectorUsed for on-site routine emergency testing, it can be widely applied in rural drinking water testing, surface water testing, river water inspection, river basin investigation, municipal sewage testing, sewage treatment testing, water plant testing, aquaculture testing and other industries.

1. The instrument is easy to use, simple to operate, and does not require high requirements from customers. It uses fully digital electrodes with fast response time and high data accuracy, and can simultaneously measure pH, water temperature, and other parameters in water bodies DO、COD、 Turbidity TDS、 Conductivity and eight indicators of ammonia nitrogen;

2. The operation interface adopts a 7-inch true color touch screen with clear display effect, and has functions such as 485 digital communication interface, abnormal alarm, automatic saving of power-off data, and automatic recovery of working status after restart.

3. Customized products (can be customized according to customer needs)

【 Sensor Features 】

1. Dissolved oxygen electrode: Designed with no dissolved oxygen film or electrolyte, it has small drift, fast response, and short polarization time; Not sensitive to dirt; Almost unaffected by flow velocity; Direct air calibration is possible without the need for zero point calibration.

2. PH/temperature electrode: adopting a composite double salt bridge electrode design, suitable for harsh environments, with long electrode life; The temperature compensation adopts imported high-quality PT1000 probe, with an accuracy of ± 0.1 ℃ and high stability.

3. Conductivity/TDS electrode: Adopting a quadrupole electrode design, it has good linearity, high accuracy, wide range, stable electrode constant, and is not affected by polarization. The concentric ring design has good stability and is not affected by flow rate.

4. COD/turbidity electrode: Adopting a digital modulation filtering dual beam electrode design to eliminate environmental impact, imported infrared LED light source with a service life of over 10 years, no reagents required, and no secondary pollution.

5. Ammonia nitrogen electrode: designed with in-situ measurement electrode, no need for reagents, no need for pretreatment, and low maintenance; It has pH, potassium ion, and temperature compensation functions, suitable for various occasions, accurate measurement, extremely low detection limit, and small data drift.
