Best Benchtop Conductivity Meter

Thermo Scientific Orion Star A211 Benchtop pH/ISE/mV/Temperature Meter

Thermo Scientific Orion Star A211 pH Benchtop meter with pH range: -2.00 to 20.00.
Large, backlit graphic LCD display shows pH/mV/RmV and temperature along with electrode status, time, date, sample ID, user ID and calibration points.
AUTO-READ locks in the stable reading on your screen, ready indicator alerts when readings are stable, and timed reading gathers data in specific time intervals.
Included electrode arm and newly-designed probe holder make it easier to maintain and place probes into samples.
Works with almost every AC power source with the included universal power adapter, or use four AA batteries (sold separately) to run the meter on DC power.

✅ 【Optimal Solution】 The ALANMOND plant water indicator is an advanced tool that allows you to check the volumetric water content in the soil, allowing you to make sure the plants are properly taken care of..
✅ 【How it Works】 Our plant moisture gauge makes use of the different conductivity of the 2 metals at the tip of the prove. Since water is a better conductor, then the higher the moisture level the greater the conductivity. This way, our hydrometer soil relies on durable indicators without using a battery..
✅ 【Practical Device】 The plant water meter ensures accurate and instant testing results, so you can check for the humidity level of the soil in a quick instant. The dial is large and clear, which makes it very easy to read, especially since it includes ten scales..
✅ 【Universal Use】 Our houseplant water meter is great for small gardeners or taking care of indoor plants but it’s also of great use in landscape irrigation, agriculture, and even research. Since every plant has different humidity requirements, it is important not to over-water the soil or let is get too dry..
✅ 【Extreme Accuracy】 Because it uses a mechanical device based on conductivity difference, this plant moisture meter indoor is very accurate and pr....
