Supports simultaneous connection of up to three electrodes, enabling multi-parameter measurement in a single device.
GLP data management with 1,000 sets of data storage and convenient USB data output for analysis and reporting.
Built for demanding field applications — IP57 waterproof, silicone-protected sockets, and grip-enhanced housing provide excellent drop and impact resistance.
Cross-Platform PC-Link Software (Windows & Mac) — No installation required—just plug in and retrieve all stored measurements at once. Offers real-time charting, immediate visual feedback, and one-click export to CSV or professional PDF reports (including measurements, calibration date, pH electrode slope, offset, meter model and serial number).
Integrated foldable stand allows the meter to transition easily between field use and benchtop operation.
Equipped with the 201T-F 3-in-1 pH/Temperature Electrode, featuring Apera’s proprietary lithium lead-free glass membrane for fast, accurate readings for general water solutions.
Automatic 1 to 3 point calibration with reminders and last-calibration date review; automatically recognizes pH 1.68, 4.00, 7.00, 10.01, and 12.45 standards.
Built-in self-diagnosis ensures proper calibration and provides guidance for correcting common pH issues.
Universal BNC connector, fully compatible with LabSen® Series professional electrodes for specialized applications.
ORP measurement capability when paired with an optional 301Pt-C ORP electrode.
The 2301T-S Conductivity/Temperature Electrode uses a firm platinum black sensor, delivering ±1% F.S. accuracy across an ultra-wide range (0–200 mS/cm).
Single-tap switching between conductivity, TDS, and salinity modes.
Automatic 1 to 3 point conductivity calibration with reminders and last-calibration date review.
Self-diagnosis function assists users in completing proper conductivity calibrations and resolving common issues.
Adjustable TDS conversion factor from 0.40 to 1.00 for different applications and water matrices.
