Overview
The Sanxin Peray Portable and Benchtop Electrochemical Analyzer Series represents a comprehensive family of precision pH, conductivity, ORP, dissolved oxygen, ion concentration, turbidity, and acid/alkali concentration instruments engineered for laboratory, field, quality control, environmental monitoring, food & beverage, pharmaceutical, and educational applications. Built upon potentiometric, conductometric, polarographic, and optical sensing principles, each instrument integrates robust analog signal conditioning, high-input-impedance (>1×1012 Ω) circuitry, temperature-compensated measurement algorithms (ATC or manual), and multi-point calibration routines compliant with ISO/IEC 17025 traceability requirements. The series spans entry-level pen-type meters (e.g., SX600) to GLP-grade benchtop analyzers (e.g., PH9500, PC9500) featuring 0.001-pH resolution, ±0.002-pH accuracy, and dual-sensor simultaneous measurement capabilities — all calibrated against NIST-traceable reference standards.
Key Features
- Modular electrode architecture supporting interchangeable, application-specific sensors: LabSen® glass pH electrodes (food-grade titanium穿刺, pure-water L-membrane, HF-resistant, high-alkali HA-membrane), platinum ORP electrodes, polarographic DO probes (DO500), optical DO sensors (DO803), solid-state ion-selective electrodes (F−, Na+, Ca2+, NO3−), and platinum black or glass conductivity cells (K = 0.1–10 cm−1).
- Intelligent auto-ranging and automatic parameter recognition — instruments detect connected electrode type (pH, EC, DO, ISE) and configure measurement range, units, and compensation settings without user intervention.
- Advanced temperature compensation: Automatic (0–100 °C) or manual; supports linear, non-linear (pure water/ammoniated water), and configurable β-coefficient algorithms per ISO 7888 and ASTM D1125.
- GLP-compliant data management: Up to 2000 storage slots with timestamp, electrode ID, calibration history, operator ID, and audit trail export via USB or RS-232. Select models support FDA 21 CFR Part 11–compliant electronic signatures and secure user access levels.
- Rugged industrial design: IP67-rated pen meters (SX6xx); splash-proof benchtop housings (MP5xx, PH9xx); corrosion-resistant POM, titanium, and stainless-steel probe bodies; and chemically inert sensor membranes certified for repeated exposure to aggressive matrices (e.g., HCl, NaOH, dairy, soil, wastewater).
Sample Compatibility & Compliance
Sanxin Peray analyzers are validated for use across diverse sample matrices including aqueous solutions, beverages, dairy products, meat and cheese (via穿刺 electrodes), soil slurries (GS2, SX811-SL), hydroponic nutrient solutions, ultrapure water (LabSen803/801), wastewater (LabSen333), high-salinity seawater (5052), hydrogen fluoride solutions (LabSen833), and viscous emulsions. All pH and ion-selective electrodes meet ISO 8655-4 performance criteria for repeatability (<±0.02 pH over 3 h) and drift (<0.002 pH/h). Conductivity cells comply with ASTM D1125 Annex A2 for cell constant verification and are supplied with NIST-traceable KCl standard solutions (1413 µS/cm, 12.88 mS/cm, 84 µS/cm). Dissolved oxygen sensors adhere to ISO 5814:2012 (electrochemical) and ISO 15839:2006 (optical) for response time (<30 s @ 90%), zero-current residual (<0.1 mg/L), and salt/pressure compensation protocols.
Software & Data Management
Instrument firmware supports full bidirectional communication via USB or RS-232 using the proprietary PC-Link suite (Windows/macOS compatible), enabling real-time graphing, report generation (PDF/CSV), calibration certificate printing, and batch export of GLP-compliant datasets. The software implements secure data encryption, version-controlled method templates, and automated compliance checks for ISO/IEC 17025 Clause 7.7 (result reporting) and USP analytical instrument qualification (AIQ) documentation. For regulated environments, optional audit-trail modules log every parameter change, calibration event, and data export with immutable timestamps and user credentials — satisfying FDA 21 CFR Part 11 Subpart B requirements for electronic records and signatures.
Applications
- Food & Agriculture: pH profiling of dairy, fermented foods, meats, fruits, and hydroponic nutrient tanks; TDS/salinity monitoring in brines and irrigation water; acid concentration (H2SO4, HCl) in processing lines.
- Environmental & Wastewater: Field-based pH, EC, DO, and turbidity (TN500/TN450) measurements per EPA Method 180.1 and HJ 1075-2019; ORP monitoring in bioreactors and denitrification zones.
- Pharmaceutical & Biotech: USP pH validation in purified water systems; conductivity testing per USP ; ion quantification (Na+, Cl−, F−) in excipient solutions.
- Academic & Research: Teaching labs utilizing SX7xx portable platforms with multi-parameter capability; research-grade ion-selective analysis (Ca2+, NH4+, NO3−) on MP523-series instruments with dual-reference electrode configurations.
- Industrial Process Control: Continuous monitoring of boiler feedwater (YD200/YD300 hardness), plating baths (acid/alkali concentration SX5150), and semiconductor rinse water (PC9500 ultra-low conductivity mode).
FAQ
Are Sanxin Peray instruments compliant with international calibration standards?
Yes. All pH and conductivity instruments ship with factory calibration certificates traceable to NIST SRM 186, NIST SRM 3159, and NIST SRM 1861. Calibration protocols follow ISO/IEC 17025, ASTM D1125, and USP /. Certificates include uncertainty budgets and as-found/as-left data.
Do the portable meters support GLP data logging?
SX800-series and higher portable models (e.g., SX825, SX836) store ≥1000 GLP-compliant readings with date/time stamp, electrode ID, calibration history, and operator code. Pen-type meters (SX6xx) provide basic timestamped storage but lack full audit trail functionality.
Can I use third-party electrodes with Sanxin Peray benchtop analyzers?
Yes — all MP5xx, PH9xx, and PC9xx instruments feature universal BNC + mini-DIN inputs compatible with standard pH, ORP, conductivity, and ion-selective electrodes from major manufacturers (e.g., Metrohm, Thermo Fisher, Hanna), provided they meet input impedance and voltage range specifications.
What is the warranty and service support coverage?
Sanxin Peray offers a 24-month limited warranty on instruments and 12 months on consumable electrodes. Global technical support includes remote diagnostics, firmware updates, calibration assistance, and access to an authorized service network across North America, EMEA, and APAC regions.
Are software updates and firmware patches available post-purchase?
Yes. Registered users receive free lifetime firmware updates via the Sanxin Peray Support Portal. Critical security patches, regulatory compliance enhancements (e.g., new 21 CFR Part 11 features), and metrological improvements are distributed quarterly with version-controlled release notes and installation guides.
