Get Hanna and test with confidence! Designed to bring simplicity to salinity testing during the any process, the HI98319 Marine Salinity Tester measures conductivity (EC) to determine the salinity of natural and artificial seawater. Within seconds, the salinity and temperature are digitally displayed on the LCD. Displays results in parts per thousand (ppt), Practical Salinity Units (PSU), or specific gravity (S.G.). Comes with all the necessary solutions and batteries- everything you need to get started measuring right away. Ideal for testing salinity in aquariums, field, and industrial settings. **For best results, please calibrate monthly.**. {To ensure accuracy of measurements: Use fresh calibration standards for each calibration. Rinse the tester with purified water and dry off with a soft tissue before calibrating or taking measurements. Calibrate monthly with regular use or more often with frequent use. Inspect the tester to see if foreign material is detected in the openings housing the electrodes. A more thorough cleaning may be made using a non-abrasive detergent, and a soft material such as cardboard, to dislodge the material. Rinse thoroughly with a steam of running tap water and jetting the steam through the opening. Shake excess water and rinse in purified water. Dry off and recalibrate the tester before using. Store with the protective cap on.} *Remember the black button to change the settings is underneath the battery cover* Care and Maintenance To ensure accuracy of measurements: Use fresh calibration standards for each calibration.

• Waterproof and floats!
• Includes 4x of the Salinity Calibration Fluid Packets.
• Automatic Calibration – A 35.00 ppt solution is used for calibration and automatically recognized when in calibration mode.
• Displays results in parts per thousand (ppt), Practical Salinity Units (PSU), or specific gravity (S.G.)
• Salinity readings are performed by an amperometric graphite probe that resists oxidation, providing better repeatability in measurements. The use of graphite also reduces the polarization effect common with testers that use two stainless steel pins.

The Hanna Ammonia Low Range Checker bridges the gap between simple chemical test kits and professional instrumentation. Chemical test kits have limited accuracy and resolution since they rely upon the human eye to discern differences in color. Professional instrumentation incorporates a light source such as an LED or tungsten lamp with a filter and a light sensing detector to precisely determine absorbance and ion concentration. Professional instrumentation offers greater resolution and accuracy but can cost hundreds of dollars. The Hanna Ammonia Low Range Checker uses a fixed wavelength LED and silicon photo detector to provide the accuracy of professional instrumentation at the affordable price of a chemical test kit.

Product description

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 ppm on the display. Use for quick and accurate on the spot analysis. Single button operation: zero and measure. Range: 200 to 600 ppm. Resolution: 1 ppm. Accuracy at 25 degree C: +/-6% of reading. Light Source: light emitting diode at 610 nm. Light Detector: Silicon Photocell. Environment: 0 to 50 degree C (32 to 122 degree F); max 95% RH non-condensing. Battery Type: 1.5V AAA. Auto-off: after 10 minutes of non-use. Dimensions: 81.5mm x 61mm x 37.5mm (3.2" x 2.4" x 1.5"). Method: adaptation of the zincon method.

The HI781 Marine Nitrate Low Range Colorimeter is designed to accurately determine low range nitrate levels in saltwater aquariums and marine applications. With a digital read out, there is no more struggling to determine colors visually. The HI781 CheckerHC (Handheld Colorimeter) is a simple, accurate, and cost-effective way to measure nitrate from 0.00 to 5.00 ppm (as NO3–) in your saltwater aquarium. For samples containing 5.0 to 50.0 ppm nitrate, follow the approved dilution procedure. Nitrate is a by-product of the Nitrogen cycle. Excessive amounts of nitrates in a reef aquarium can promote the growth of undesirable organisms including algae and dinoflagellates while insufficient amounts can lead to starvation in which SPS and other corals will show signs including the loss of color and paleness. The HI781 Nitrate Checker HC is a handheld colorimeter that uses the Beer-Lambert principle to determine the concentration of nitrate colorimetrically. The HI781 is designed specifically to measure low levels of nitrate in a saltwater aquarium.

• More accurate than chemical test kits.
• Built-in timer so you don't miss a step.
• No errors with a digital readout
• Ideal for aquariums and marine biology applications
• For samples containing 5-50 ppm nitrate, follow the dilution procedure
