Water Supply JH-9 type hexavalent chromium-line analyzer

JH-9 type Water hexavalent chromium-line analyzers is our guide through environmental monitoring experts and users proposals set a lot of theory and practice of experiments and the development of water quality monitoring instrument, which designed and developed in full compliance with relevant national environmental standards. JH-9 using the spectrophotometric principle, entirely equivalent to GB7467-87, can be analyzed directly in the field of water Cr (Ⅵ) concentration, wide measurement range, can be widely used in water analysis environmental monitoring, labor protection, research institutions and other sectors . Main features: automatic cleaning power and water pump intuitive protection fault detection and protection function operation, industrial 320 × 240 dot matrix LCD display section and the photo some chemical completely separate to prevent their interaction with self-diagnosis function, can identify whether missing Water samples or reagents unique hybrid technology bubble, ensuring that the sample and reagents sufficient reaction low pharmaceutical consumption, preparation time is short, simple operation, without special training with automatic correction function, can be deducted to reduce reagent reagent blank error automatically store measurement data, micro-printer configuration, field measurement data print Technical parameters: Measuring import 538nm LED light source flexible measuring time setting (≥15min) reagent replacement 4 to 5 weeks / secondary power supply voltage (220 ± 22) V power supply required frequency (50 ± 0.5 ) Hz range 0-5mg / L accuracy ≤ ± 5% accuracy ≤ ± 5% detection limit of 0.01mg / L straight ≤5% Zero drift ≤ ± 5% FS span drift ≤ ± 5% FS compare actual water samples Experimental ≤10% MTBF ≥720 hours / time data storage can be stored for more than three years of data, provide ways to search by date or concentration signal output from each channel independently isolated 4 ~ 20mA current output signal and RS232 or RS485 serial Dimensions 600 × 1300 × 450mm Weight Approx. 65Kg (free agent)
