The Hanna Free Chlorine 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 Free Chlorine 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.

Residual Chlorine MeterBrand Lohand InstrumentModel LH-C10FThis instrument adopts the DPD photometric method, which is specially used to determine the concentration of residual chlorine in water samples. A large number of experiments have proved that this method is simple and quick to operate and has high sensitivity. The instrument is small in size, light in weight, easy to carry, suitable for field and field use.

This meter offers a superior optical system that utilises a reference detector and narrow band interference filters for extremely fast and repeatable measurements.No warm up time before taking a measurementTutorial mode for step-by-step instructionsUses either powder or cost saving liquid reagentsCAL CheckThe HI-97710 has an innovative optical system that offers superior performance in accuracy, repeatability, and the short amount of time it takes to perform a measurement.This compact, waterproof meter is extremely user friendly with a tutorial mode that walks the user graphically, step by step, in performing a measurement.The use of a backlit dot matrix LED allows the use of virtual keys which makes the operation of the meter very intuitive including selecting different methods, reviewing GLP data, recalling the last 50 measurements, and customising the meter to user preferences.HI-97710 is waterproof including the cuvette holder that is designed with ridges to protect the optical path from getting scratched by the cuvette and a protected battery compartment that holds three AA batteries. The compact design fits comfortably in the hand for use in the field or on a table for benchtop use. The LCD is 71 mm (2.75") by 37 mm (1.6") and is backlit for easy viewing under all conditions.Stable Light Source:The internal reference system of the HI-97710 photometer compensates for any drifts due to power fluctuations or ambient temperature changes. With a stable source of light the readings are fast and stable between your blank (zero) measurement and sample measurement.High Efficiency Light Source:LED light sources offer superior performance compared to tungsten lamps. LEDs have a much higher luminous efficiency, providing more light while using less power. They also produce little heat, which could otherwise affect electronic stability.High Quality Filters:Improved optical filters ensure greater wavelength accuracy and allow a brighter, stronger signal to be received. The end result is higher measurement stability and less wavelength error.Greater Light Yield:A focusing lens collects all of the light that exits the cuvette, eliminating errors from imperfections and scratches that may be present in the glass. The use of the convex lens reduces the need for indexing cuvettes.CAL Check Functionality:Hanna's exclusive CAL Check feature allows for performance verification and calibration of the meter using NIST traceable standards. Our CAL Check standard vials are developed to simulate a specific absorbance value at each wavelength to verify the accuracy of subsequent readings.Multiple Measurement Methods:Users can select the use of powder reagents supplied in packets or the use of low cost liquid reagents supplied in a dropper bottle.Built-in Reaction Timer:Waiting the proper reaction time is of key importance when performing colorimetric measurements. The countdown timer displays the time remaining until a measurement will be taken, ensuring consistent results between sample measurements and users.Large Cuvette Size:The sample cell of the HI-97710 fits a round, glass cuvette with a 25 mm path length. The relatively long path length of the sample cuvette allows the light to pass through more of the sample solution, ensuring accurate measurements even in low absorbance samples.Intuitive Dot Matrix Display:Designed with a backlit, graphic LCD, plus virtual keys, a battery status indicator, and error messages. Users will find the meter interface intuitive and easy to read. A dedicated help key provides information relating to the current meter operation, and can be used at any stage in the setup or measurement process to show contextual help.Auto-off Protection:The meter uses three common AA batteries that allow for about 800 measurements to be taken. The auto-off feature automatically shuts off the meter after 15 minutes of inactivity in order conserve battery life.About ChlorineChlorine is a common chemical used by many due to is disinfection properties.Free chlorine can exist in two forms and which form is present is based on the pH. At pH less than 7.6, the predominate form is hypochlorous acid (HOCl), while at pH greater than 7.6, the hypochlorite (OCl-) form becomes predominate.This is very important when it comes to preventing biological growth in water or keeping a swimming pool safe since hypochlorous acid is 100 times more effective as a sanitiser.Total chlorine represents both the free chlorine and combined chlorine present.Combined chlorine is the chlorine bound to nitrogen substances such as ammonia. In swimming pools, combined chlorine is what we can smell and is irritating to the eyes.The free chlorine measurement is subtracted from the total chlorine measurement in order to know how much combined chlorine is present. HI-97710 is designed to measure pH and low levels of free and total chlorine in water up to 5.00 mg/L (ppm).Advanced optical systemLED that generates very little heat.8 nm narrowband interference filter that is accurate to +/- 1 nm and offers 25% increase in light efficiency.Reference detector that modulates the voltage to LED for consistent light output.A concave focusing lens that reduces errors from imperfections in the cuvette.Also available as a kit: HI-97710C pH, Free & Total Chlorine Portable Photometer KitThe HI-97710C kit is supplied with a meter, CAL-Check standards, cuvettes (2), caps (2), plastic inserts for cuvettes (2), scissors, a cuvette cleaning cloth, 1.5V AA batteries (3), instruction manual, and an instrument quality certificate.

One of the most important steps of swimming pool maintenance is water balance to keep the pool/spa water- SAFE. chlorine based tablet pool, pH needs to be correct. If pool water is not balanced correctly then chlorine sanitizer won't be working on killing germs and bacteria that can cause diarrhea/ear/skin infections.- COMFORTABLE. water balance needs to be correct or it will affect skin/eyes. pH should be neither too acidic nor basic in order to feel comfortable- CORROSION-FREE. imbalanced pool can be corrosive to the liner, ladders/hand rail and others like pumpCL2 can also get eaten up if lot of nitrogen (from debris, pee, sunscreen, sweat).It is best to test CL2 and pH levels all the time as they change daily depends on pool usage.High alkaline water leads to high pH. Low alkaline water leads to low pH. Keeping your pH levels w/in proper range is important for keeping your equipment and pool finish intact. Your chlorine will dissolve quicker with low pH level. High pH levels make chlorine inactive.This gives you useful info to adjust Chlorine and pH of your pool accordingly, if your tested results are beyond the recommended range below. A great tool that you might need for maintaining your pool water.Set Includes:1 x pH and Free Chlorine Tester with Probe1 x English Instruction Manual
