The APERA PH850-MS Portable pH Meter is engineered for professional pH measurement in test tubes and small liquid samples (>0.2 mL). Equipped with the Swiss-made LabSen 243-6 3-in-1 pH/Temperature electrode, featuring long-life reference system and unique semi-micro cylindrical sensor, this device makes precise micro-sample pH analysis easier than ever. Operating in the 0-14 pH range with ±0.01 pH accuracy and temperature range of 0-100°C (32-212°F), it supports 12 automatic calibration buffer recognition modes with auto temperature compensation and stable reading/auto-hold display function. The digital filter technology enhances response time and measurement accuracy. Smart functions include automatic self-diagnostics, out-of-range alerts, calibration error detection, and electrode validity warnings. Intelligent features also include auto-calibration, auto-lock, easy parameter adjustment, pH electrode slope display, and auto shut-off. Built with reliable design: foldable stand for benchtop operation, soft silicone case for secure grip, connector protection cap with IP57 water-resistant rating, powered by 3 AA batteries. RoHS and CE certified with 2-year warranty.

Frequently Asked Questions

What is the minimum sample volume required for measurement?
The APERA PH850-MS is designed for samples >0.2 mL, making it ideal for test tubes and small liquid samples. The semi-micro LabSen 243-6 electrode is specifically engineered for micro-sample analysis.
How does automatic temperature compensation work?
The built-in temperature sensor automatically measures sample temperature and adjusts pH readings accordingly (0-100°C range). Manual temperature compensation mode is also available if needed.
Is this meter suitable for benchtop or portable use?
Both. The foldable stand allows benchtop operation, while the compact design (88 × 170 × 33 mm) and included soft silicone carrying case make it portable for field measurements.
What is the IP57 water-resistant rating?
IP57 means the device is dust-proof and protected against water immersion up to 1 meter for 30 minutes, making it suitable for lab environments with moisture or accidental splashes.
How long does the electrode last?
The LabSen 243-6 features a long-life reference electrode system. Typical lifespan is 1-2 years depending on usage and storage conditions. The device includes smart diagnostics to alert when electrode replacement is needed.
What smart diagnostic features are included?
The meter features automatic self-diagnostics including out-of-range measurement detection, calibration error alerts, electrode validity warnings, auto-calibration validation, and automatic shut-off after inactivity.
What is the warranty coverage?
The APERA PH850-MS includes a 2-year manufacturer's warranty and is RoHS and CE certified, ensuring compliance with European and international standards.
