Reference class voltmeter sakuraProof

Reference class voltmeter sakuraProof

Adopts vibration capacity type microcharge meter technology at the national standard level. Uses a lock-in amplifier method in the amplifier circuit. Achieves high precision and stable measurements.

- By adopting a lock-in amplifier and using a vibration capacitor in the AC signal circuit, it has become possible to achieve amplification with reduced noise. - To minimize the influence of the human body, the operation buttons have been eliminated from the main unit. - Control and measurement are performed using an add-in software for Microsoft Excel. Additionally, the measurement values are directly imported into Excel cells, which helps prevent errors in data acquisition and reduces the burden on the measurer.

Simple Soil Eh Meter 'FV-702'

Simple Soil Eh Meter 'FV-702'

For long-term measurement of soil redox potential! Simple soil Eh meter with data memory function.

The "FV-702" is a simple soil Eh meter used to evaluate the generation of sulfides that harm rice crops and the production of methane that promotes global warming. It features a compact size and large memory capacity for easy continuous measurement. By connecting it to a platinum electrode and a reference electrode (both sold separately), you can measure the oxidation-reduction potential (Eh) of the soil (mainly in rice fields) and record it in a logger. 【Features】 - Easily measure long-term soil Eh - Equipped with data memory function, capable of recording 60,000 data points (for 2,500 days at 1-hour intervals) - Measurement range of -1.09V to 1.51V, resolution of 0.26mV (after scaling) - Can be installed outdoors (simple waterproof design) *For more details, please refer to the PDF document or feel free to contact us.
