Water analyzer W501-DP10.1

aluminumacidspray

Product InformationThe Online Peracetic Acid Analyzer consists of an instrument with an LCD display for PAA value, optional aqueous solution pH value, and working status; outputs analog, digital, and switching signals. It includes a German-made P10.1 sensor that resists chemical interference (mainly from surfactants), reduces pH dependence, and is not restricted by water quality. With fast response, stable performance, low cost, and minimal maintenance, it provides users with reliable and accurate data.This analyzer is mainly used in fruit and vegetable disinfection, CIP bottle washing, medical endoscope disinfection, and cold tank lines.Working PrincipleThe measurement system consists of two parts: the instrument W501 and the P10.1 sensor. The instrument displays the PAA value (main measured value), the pH value of the aqueous solution (optional pH electrode), and the working status. It outputs analog, digital, and switching signals. The sensor is an original imported RG brand from Germany and operates based on the film-covered three (dual) electrode constant-current method. It features anti-interference and anti-pollution.Application FieldsFruit and vegetable disinfection: 0 - 200mg/LCIP bottle washing: 0 - 2000mg/LMedical endoscope disinfection: 0 - 5000mg/LCold tank lines (canning lines and transportation pipelines): 0 - 5000mg/LFunctional FeaturesDual-channel access, configurable as required.Plug-and-play sensors for quick and easy installation and electrode replacement.Simple interface operation to reduce errors and ensure reliable results.Visual operation on LCD screen with comprehensive interface.Multiple data output methods including 4-20mA and MODBUS RS485.Controller supports wall-mounting, panel-mounting, and pipe-clip mounting.Aluminum alloy construction for high strength, oxidation, and corrosion resistance.Technical ParametersSpecificationDetailed informationMeasurement ParametersPeracetic Acid, pH (optional)Measuring Ranges0–20.00mg/L; 0–200.0mg/L; 5–500.0mg/L; 5–2000mg/L; 50–5000mg/L; 50–20000mg/L; 500–50000mg/LLower Limit of Measurement0.01mg/L (depending on the electrode)Resolution0.01-100mg/L (depending on the measuring range)Accuracy (@25℃, pH 7.2)0-1000ppm: ±2% of measured value or ±3ppm (whichever is larger); 1000-2000ppm: ±5% of measured value or ±5ppm (whichever is larger)Response timeT90≈8 minutesDriftApprox. -1% per month (after calibration at 25℃ and pH 7.2)PH range1.0 - 8.0 (depending on the electrode)Maintenance Cycle≥90 daysOperating temperature0 - 45℃DisplayLCD liquid-crystal screenPower supply105–235VAC, 50±1Hz / 24VDC±5% (DC optional)Power≤12W (including the sensor)Analog OutputTwo analog outputs (load resistance < 500Ω)Digital outputRS485 interface, MODBUS RTU protocolRelay outputThree-way relay: 5A 250VAC, 5A 30VDC; Three-way relay: 3A 250VAC, 3A 28VDC or 120VACMaterialBottom shell: Cast aluminum with plastic spray coating; Top cover: PA66 + 30GF with paint coatingSize145*145*174mm (H*W*D)Weight1.8kg (not including the sensor)Waterway interface2-inch or 3-inch hose (custom made)Flow rateIn flow chamber: 250–500mL/minProtection levelIP65Water pressure≤6 bar (with pressure-reducing valve)Working humidity<90%, no condensationWorking temperatureInstrument: -15℃–50℃; sensor water temperature: 0.1℃–45℃Storage temperatureInstrument: -20°C–60°C; sensor: 0.1°C–55°CFAQ – Frequently Asked QuestionsProducts are designed and manufactured in China, following international quality standards.OEM/ODM services and private labeling available.Products comply with CE, RoHS, and other certifications.Fast and reliable international shipping.Samples available before bulk orders.Standard products ship within 5–7 days after order confirmation.24/7 technical support and warranty service.Remote technical assistance and English manuals for international clients.Ordering available via email or website inquiry.Over 30 years of manufacturing experience, advanced technology, and strict quality control.Characteristics / Technical SpecificationsModel: W501-DP10.1Measurement: Peracetic Acid, pH (optional)Measuring Ranges: 0–20.00mg/L up to 500–50000mg/LResolution: 0.01-100mg/LAccuracy: ±2% or ±3ppm (0-1000ppm), ±5% or ±5ppm (1000-2000ppm)Response time: T90≈8 minutesDrift: -1% per monthPH range: 1.0 - 8.0Maintenance Cycle: ≥90 daysOperating temperature: 0 - 45℃Display: LCDPower supply: 105–235VAC/24VDCAnalog/Digital Output: 4-20mA, MODBUS RS485Protection: IP65Material: Cast aluminum, PA66 + 30GFSize: 145*145*174mmWeight: 1.8kg
