Hanna Instruments Launches New Calcium Colorimeter on the Checker HC Line
WOONSOCKET, RI- (July 18, 2011) Hanna Instruments is excited to introduce the new calcium colorimeter to the Checker HC line. The new digital HI 758 Calcium Checker HC is an easy-to-use colorimeter for saltwater calcium testing, which is ideal for aquaculture and aquariums applications.
Calcium presence in water supplies results from passage over deposits of limestone, dolomite, gypsum and gypsiferous shale. Its concentration may extend from 0 to several hundred milligrams per liter, depending on its source and treatment. Calcium is necessary in plant and animal nutrition since it is an essential constituent of bones, shells and plant structures. Calcium in water as carbonate is one of the primary components of water hardness which can cause pipe or tube scaling.
The HI 758 Calcium Checker HC is extremely simple to use. First, zero the instrument by adding Reagent A, deionized water and 0.1 mL of sample into the vial. Insert into the HI 758 and press the button. Next, remove the vial and add Reagent B and shake to dissolve. Reinsert into the Checker HC and press the button to read the calcium concentration in parts per million on the display. It’s that easy!
The Checker HC line of products is manufactured in our European state-of-the-art ISO 9001:2000 production facility. Each Checker HC is CE compliant to EN 61326-1 and EN 61010-1 standards.
Portable pH Meter with Intellegent Electrode & Calibration Check
Woonsocket, RI (May 12, 2011) HI 98140N is one of the most innovative portable pH meters ever offered. It features IP 67 waterproof protection, GLP (Good Laboratory Practice) capabilities, a dual level LCD and uses HANNA intelligent electrodes.
These electrodes incorporate a chip which memorizes the calibration data performed with a specific instrument. When the "intelligent electrode is attached to the meter again, it is automatically recognized. This technology allows the operator to optimize time and efficiency with unsurpassed safety. It avoids erroneous measurement readings in the event that the pH electrode is substituted after calibration. This electrode series are equipped with a built-in temperature sensor; no need for an additional temperature probe here!
The HI 98140N can also store up to 500 measurements complete with date and hour. Stored data can be displayed later or downloaded to a computer through an RS232 serial port and the HI 92000 Windows® compatible software.
