Dissolved oxygen meter METRINCO LA801D

METRINCO LA801D is a portable LA-800 series meter for measuring dissolved oxygen concentration and water temperature. Supplied with a DO-LA1G membrane dissolved oxygen sensor, a separate TPLA-1 temperature probe, spare membrane caps and electrolyte.

Monitoring dissolved oxygen in ponds and fish farms, aquaculture systems and wastewater treatment stages, as well as laboratory measurements of water samples. Suitability for a specific method depends on its requirements.

LA801D features

• Dissolved oxygen. DO-LA1G galvanic membrane sensor, range 0.01 to 20.0 mg/dm³, error ±(0.2 mg/dm³ + 1 digit). Air calibration (101.7 % saturation) and, if needed, an additional zero-oxygen solution calibration. Salinity (0–50 ppt) and altitude (0–20,000 ft) compensation. Sensor cable length: 115 cm, excluding the connector and electrode body.
• Separate temperature probe. The TPLA-1 measures sample 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.
• Replaceable electrodes, sensors and consumables. Electrodes and sensors are replaced separately from the meter; spare electrodes, sensors, calibration solutions, electrolyte and membrane caps can be ordered from the manufacturer.
• Convenient operation: auto-hold of a stable reading in DO 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

In this configuration the meter is supplied without conformity assessment. The LA-800 analyzer type is approved (type-examination certificate UA.TR.001 29-26 of 06.08.2026, module B, SE “Ukrmetrteststandart”). Module F conformity assessment is available for the meter — the manufacturer arranges it as a separate order at the current price. Metrological calibration in a laboratory accredited to DSTU EN ISO/IEC 17025 is also available for an additional fee. This version is supplied with a user manual in Ukrainian and a warranty card.
