Brief Description:
The Nutradip Tri-Meter (CMS) Continuous Monitoring System Meter gives you the ability to monitor pH level, Total Dissolved Solids (TDS) and Temperature all at the same time. This portable/continuous monitoring system requires no batteries, just plug it in a AC wall receptacle and the meter will remain in a calibrated mode for months. Reliable and Accurate. Comes with ac adaptor.One and two point manual calibration.For hydroponic or aquarium use. Potential Hydrogen (pH), are found in all aqueous solutions. Potential Hydrogen can be beneficial in controlled concentrations, but can quickly change to undesired levels of acidity of alkalinity of the solution. pH can accumulate to toxic levels in sensitive envionments like plants, aquariums or drinking water, therefore the need to measure pH is very important. The Potential Hydrogen Monitoring System (pHMS) is an effective pH management tool.

Brief Description:
The Green Air Products Carbon Dioxide Digital Sequencer (CDDS-2) transforms the CO2 monitor into a powerful and versatile controller. The CDDS-2 provides a easy to use set point controller which enables the user to adjust CO2 level and span. CO2 values are adjustable in 10 ppm increments from 0 to 5000 ppm. The span between CO2 "On" and CO2 "Off" (hysteresis) is also adjustable in 10 ppm steps up to 300 ppm differential. The LED changes color to indicate CO2 function status. The CDDS-2 also provides a switchable photo sensor to disable CO2 production during darkness periods. The CDDS-2 controller has a standard 110 VAC outlet to operate CO2 producing or venting equipment. The MODE button switches between CO2 enrichment or CO2 venting functions. Enrichment is the normal mode for CO2 enrichment operations. Venting mode is for purposes of removing excessive levels of CO2. This is used for excess CO2 accumulation in hospitals, class rooms, factories, conference rooms, offices, laboratories and mushroom culture facilities. The CDDS-2 Carbon Dioxide Digital Sequencer features Overshoot Protection Logic programming which will automatically maintain the proper dosing parameters necessary to keep any size area enriched within a set tolerance regardless of the particular characteristics of the enclosure. If on the initial cycle, the controller senses that excess CO2 has been administered, it will automatically compensate for the next dosage. This will assure that the proper levels are constant and maintained at all times with complete accuracy and save money at the same time.
