Mini Digital Pocket pH Meter

The portable pH meter model 9020 mini is a compact, ultra-light, and easy-to-handle instrument, designed for quick pH measurements in the field, mobile laboratory, or applications outside conventional environments. Its reduced format and intuitive operation make it a practical solution for spot checks in aqueous solutions.

The equipment covers a pH measurement range of 0–14, with an accuracy of ±0.1 pH and a resolution of 0.1 pH. It incorporates automatic temperature compensation, which allows maintaining the stability and reliability of the readings in the face of thermal variations during use.

It features a one-point manual calibration system that facilitates its adjustment and maintenance. The sensor is integrated and non-interchangeable, which simplifies the design of the equipment and its daily operation. It runs on two 1.5 V batteries (included), allowing immediate use upon reception.

It is supplied with an adjustment tool and two vials of buffer solution to perform the initial calibration, ensuring correct operation from the first use.

Thanks to its reduced dimensions and ease of transport, it is especially suitable for applications in water control, agriculture, aquaculture, effluent treatment, industry, and education.

To obtain reliable results, it is recommended to rinse the electrode with distilled water before each measurement and to perform periodic calibrations with appropriate buffer solutions. In samples of high viscosity or emulsions, it is advisable to prepare an approximate 10% dilution with distilled water to facilitate the measurement.

For sanitary reasons, this product does not allow returns once used, as the electrode may deteriorate and not be suitable for reuse. It is recommended to verify its suitability before use.
