pH/ORP meter METRINCO LA801P (with conformity assessment)

METRINCO LA801P is a portable LA-800 series pH/ORP meter for measuring pH, oxidation-reduction potential (ORP) and temperature of aqueous solutions. Supplied with a PG-02 pH electrode, a separate TPLA-1 temperature probe and pH 4 and pH 7 buffer solutions. The CA version includes completion of the module F conformity assessment of the meter; its cost is included in the price, and the meter is supplied with a set of supporting documents.

Please note: ‘In stock’ indicates that the meter is physically available in our warehouse. If conformity assessment of the individual unit has not yet been completed, dispatch may take up to 14 calendar days to complete the procedure and issue the documentation.

Monitoring pH and oxidation-reduction potential of water and process solutions: water treatment, industrial laboratories, incoming and production control, teaching and research measurements. Suitability for a specific method depends on its requirements.

LA801P features

• pH. Measuring range 1.00 to 14.00 pH, maximum permissible absolute error ±0.05 pH (per the type-examination certificate); display resolution 0.01 pH. After calibration the meter shows the electrode slope (PTS), which helps detect a worn electrode in good time.
• ORP. Range −1999 to 2000 mV, error ±(2 mV + 1 digit). ORP measurement requires an OG-2 or OG-3 ORP electrode, which is ordered separately.
• Flexible calibration settings. Calibration point values for pH and ORP can be changed manually to match the buffer and standard solutions in use. pH can be calibrated at 1–5 points, and each of the five point values (defaults 1.68, 4.01, 7.00, 10.01, 12.45 pH) can be changed in the menu; ORP is calibrated at one point set within 100–1000 mV.
• Last calibration information. The Cal. Info menu shows the data of the last calibration: pH — offset, slopes, temperature with the compensation mode (MTC/ATC) and calibration mode; ORP — calibration point and offset. This lets you review the last calibration parameters and assess the pH electrode condition from its calibration characteristics.
• Separate temperature probe. The TPLA-1 measures temperature from 0 to 110 °C with ±0.5 °C error and provides automatic temperature compensation from 5 to 60 °C; temperature offset adjustment ±3.0 °C.
• BNC for pH and ORP electrodes. Electrodes connect via a standard BNC connector, and the separate temperature probe allows pH electrodes without a built-in temperature sensor to be used. Please check the compatibility of another manufacturer’s electrode with technical support in advance.
• Replaceable electrodes, sensors and consumables. Electrodes and sensors are replaced separately from the meter; spare electrodes, sensors, calibration solutions can be ordered from the manufacturer.
• Convenient operation: auto-hold of a stable reading in pH mode, MAX/MIN mode, splash-protected keypad, backlit 128×64 graphic LCD, built-in stand for bench use.
• Battery operation. Powered by four built-in 10440 (3.7 V) rechargeable batteries, charged via USB Type-C or on the LA80BS base; auto power-off adjustable from 5 to 600 s.
• Field and laboratory measurements. The meter runs on its own batteries, and with the LA80BS base it becomes a bench workstation with magnetic stirring and an electrode holder. The base can be bought later.

Data logging and PC connection

The meter lets you view the last 60 manual records (Recall mode).

Readings with date and time are written to an SD card (FAT32): manually with the STO/Enter key, or automatically by timer at intervals from 1 to 600 s. Records are saved as Excel files in the MANUAL and AUTO folders. An SD card is not included.

Via USB Type-C the meter sends readings to a PC in real time. The Windows software lets you set a sampling interval of 1–600 s, view a chart and save data to an Excel file. The software is provided on request.

LA80BS laboratory base

This version does not include the base. If a bench workstation is needed, the LA80BS laboratory base with a magnetic stirrer, stand and charging can be bought separately. It does not change the meter’s rated metrological characteristics.

Metrological documents

With conformity assessment of the meter. The CA version includes completion of the module F conformity assessment of the individual meter based on the approved type (type-examination certificate UA.TR.001 29-26 of 06.08.2026, module B, SE “Ukrmetrteststandart”); the cost of the assessment is included in the price. Documents: user manual in Ukrainian, warranty card, copy of the declaration of conformity, copy of the type-examination certificate, copy of the module F certificate of conformity.

Metrological calibration in a laboratory accredited to DSTU EN ISO/IEC 17025 is available for an additional fee. Conformity assessment, verification and calibration are different procedures.
