pH/ORP/conductivity/TDS/salinity meter METRINCO LA802PC

METRINCO LA802PC is a portable LA-800 series multiparameter meter for measuring pH, ORP, conductivity, TDS, salinity and temperature of aqueous solutions. Supplied with a PG-02 pH electrode, a CD-2 conductivity cell (K = 1), a separate TPLA-1 temperature probe, buffer and standard solutions.

For institutional and industrial laboratories, water treatment, production control, teaching and research laboratories — when pH, ORP and conductivity are needed in one instrument. Battery power also allows work away from the lab bench. Suitability for a specific method depends on that method’s requirements.

LA802PC 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. 1- to 3-point calibration from the buffer set 1.68, 4.01, 7.00, 10.01, 12.45; 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.
• Conductivity, TDS and salinity. With the CD-2 cell (K = 1): four subranges from 1.0 µS/cm to 200.0 mS/cm with automatic unit switching; error ±2.5 % of the upper limit of the subrange. TDS and salinity are calculated from conductivity; the TDS conversion factor is user-defined. Calibration points 0, 84, 1413 µS/cm, 12.88 and 80.0 mS/cm, plus air calibration to set zero.
• Cells with K = 0.1, 1 and 10. The cell constant is set in the menu. Rated metrological characteristics apply to the supplied CD-2 cell (K = 1); alternative cells are selected by technical support.
• 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 BNC connector, and the separate temperature probe allows electrodes without a built-in temperature sensor to be used. Therefore a compatible electrode from another manufacturer can be selected if needed — please check the compatibility of a specific model with technical support.
• Replaceable sensors and consumables. Sensors are replaced separately from the meter; calibration solutions can be ordered separately.
• 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.
• Portable and laboratory use. The meter works on its own, and with the LA80BS base it becomes a 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.

Conformity assessment and calibration

Status: without a completed metrological conformity assessment. The LA-800 analyzer type is approved by type-examination certificate UA.TR.001 29-26 of 06.08.2026 (SE “Ukrmetrteststandart”). If the instrument is later needed in a legally regulated field, it can be handed over to the manufacturer to arrange the module F procedure. Arranging the procedure separately after purchase costs more than buying the CA version straight away.

Calibration in a laboratory accredited to DSTU EN ISO/IEC 17025 is available as an additional order and is not included in the price.
