Time Mark Liquid Analytical

Liquid Analytical Analyzers and Probes are used to display, control, and transmit measurements such as pH, conductivity, ORP, DO, TDS, Concentration of NH3, and other variables for water quality.

Defining further the alphabet soup of acronyms:

• pH is an indicator of the level of acidity (0 pH) to neutral (7 pH) to alkalinity (14 pH)
• Conductivity is an indicator of how conductive is water which can vary for example with the the mineral. Common units of measure are micro ohms and micro Siemens (µΩ = µS)
• ORP (Oxygen Reduction Potential) is an indicator of the available oxygen in the water for fish and plant life and a measure of the quality of the water.
• DO (Dissolved Oxygen) is a measurement used in calculating ORP. Lower dissolved oxygen indicates organics are consuming oxygen resulting in higher ORP.
• Besides industrial processes, Concentration of NH3 (ammonia) in water is particularly important in agricultural areas where fertilizers are used. It is one of many ion specific electrodes that are available. Others include Chlorine, Ozone, Hydrogen Peroxide

Typical application consists of a measuring probe connected by cable to an analyzer. Analyzers can be multi-channel and multi-variable. They can optionally have a display and/or transmit the measurement as a 4-20 mA signal. Models stating Controller in literature include alarm relays and possibly even PID control capability.
