The Labmart LMPH1P Portable pH Meter is a laboratory-grade portable instrument for accurate pH, mV and temperature measurement. It offers a -2.00 to 20.00 pH range, 0.01 pH resolution, ±0.01 pH accuracy, automatic temperature compensation, 1–3 point calibration, 100-data memory, USB connectivity and LCD display with white backlight.

Product Overview

The LMPH1P Portable pH Meter is designed for routine laboratory measurement of pH, oxidation-reduction potential (mV) and temperature. Its portable format makes it suitable for laboratories and applications where measurements need to be performed at different locations.

The meter supports 1 to 3-point calibration with automatic recognition of USA and NIST buffer sets. Automatic electrode diagnosis helps the user assess the condition of the pH electrode, while the auto-read function detects and locks the measurement endpoint.

The instrument provides automatic or manual temperature compensation, stores up to 100 data sets, and includes a USB interface for data transfer or connection to a power adapter.
