PINPOINT® pH Controller (220V) is an inexpensive yet rugged controller, which includes the appropriate probe and calibration fluids.
This device will automate another electrical device such as a calcium reactor or magnetic solenoid for the addition of CO2 into an aquaculture or process system, and will control pH in both a downward and upward direction.
The user will select his or her own setpoint and any range of acceptable pH around this setpoint. This full featured controller will handle up to 5.0 amps at 220 VAC.
Warranty: Controller: 1 Year. Probe: 30 days.
* Preorder basis - Take approximately 1.5 - 2 months.
$17.00The HI774-25 are high-quality reagents that are pre-measured, allowing for users to achieve fast and accurate measurements with their Phosphate Ultra Low Range Checker® HC. These reagents follow the Ascorbic Acid Method in which the reaction between phosphorus and reagents causes a blue tint in the sample. By simply adding the packet of HI774-25 reagent to the sample, the reaction will take place and the HI774 will determine the concentration from the color that is produced. The results will be displayed in ppb of phosphorus. These reagents are designed to be used with samples that have an expected range of 0.00 to 0.90 ppm phosphate.
