Product Description

The Labmart LMPH15 pH Meter with Thermal Printer is a benchtop laboratory pH/ORP meter featuring 1–5 point pH calibration, automatic temperature compensation, automatic electrode diagnosis, Auto-Read endpoint detection, built-in thermal printing and 1000-data memory. It measures pH from -2.000 to 20.000 with selectable 0.001/0.01 resolution and provides ORP measurement up to ±2000 mV.

3. Detailed Product Description

Product Overview

The LMPH15 pH Meter with Thermal Printer is designed for accurate laboratory measurement of pH and ORP, with integrated temperature measurement and compensation. Its large 7-inch TFT LCD provides a clear interface for measurement, calibration and data-management functions.

The instrument supports up to 5-point pH calibration with automatic recognition of USA, NIST, DIN and user-defined buffer sets. Automatic electrode diagnosis displays pH slope and zero offset, helping users assess electrode condition during calibration.

For ORP measurements, the LMPH15 provides absolute and relative millivolt modes and 1-point offset calibration. Additional features include Auto-Read endpoint detection, high/low limit alarms, calibration-due alarms, password protection and storage for up to 1000 data sets.

An integrated thermal printer allows measurement information and calibration reports to be printed directly from the instrument. The supplied catalogue also shows dedicated print formats for pH analysis and calibration reports.
