Automated pH Measurement

Automated pH Measurement

Why Automating pH Measurement is Important Automation of pH allows for a more consistent recording of measurements undertaken. However, it is important that the automation instrument has the means to accurately control the precision of the pH test been performed. Stirrer speeds, the type of stirrer used, electrode washing and pH meter settings all play a key role in accuracy and precision of any soil or water pH test. Studies have found that automated pH measurement is far more accurate than a manual measurement as the manual method usually involves using the pH electrode to stir the medium. This results in loss of sensitivity on the pH electrode junction (glass bulb) as the abrasive nature of the stirring in this manner slowly wears away the thin wall of the glass bulb.

Total Dissolved Solids by Gravimetric Analysis

Total Dissolved Solids by Gravimetric Analysis

What are Total Dissolved Solids? Total Dissolved Solids or TDS, is a measure to identify the total soluble solids within a solution. The test is usually performed on drinking water as a high total dissolved solids measurement (greater than 500mg/l) can be harmful for human consumption. Total dissolved solids do not include gases, colloids, or sediment, but consist chiefly of Carbonates, bicarbonates, Chlorides, Sulphates, Phosphates, and Nitrates of Calcium, Magnesium, Sodium, and Potassium, with traces of Iron, Manganese and other elements.

Labfit Carbon Sulphur Analyser Overview

Labfit Carbon Sulphur Analyser Overview

Labfit Carbon & Sulphur Analyser The Labfit Carbon and Sulphur analyser is designed to determine Carbon and Sulphur in minerals and organic materials. The Labfit Carbon and Sulphur Analyser uses a vertical resistance furnace that significantly simplifies the design and makes automation much more reliable. The vertical furnace provides and “airgap” around the combustion crucible inside the combustion chamber.  This method of heating prevents any unwanted thermal shocks from cold combustion boats as used in other instrumentation. More even heating and advanced thermal insulation further reduces power consumption to less than 15 amperes at temperature.
