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

ZDYG-2088-01QX turbidity sensor light scattering method based on combination of infrared absorption, infrared light emitted by the light source after the scattering of turbidity in the sample. Finally, by the photodetector conversion value of electrical signals, and obtaining the turbidity of the sample after the analog and digital signal processing. Turbidity, a measure of cloudiness in liquids, has been recognized as a simple and basic indicator of water quality. It has been used for monitoring drinking water, including that produced by filtration for decades. Turbidity measurement involves the use of a light beam, with defined characteristics, to determine the semi-quantitative presence of particulate material present in the water or other fluid sample. The light beam is referred to as the incident light beam. Material present in the water causes the incident light beam to scatter and this scattered light is detected and quantified relative to a traceable calibration standard. The higher the quantity of the particulate material contained in a sample, the greater the scattering of the incident light beam and the higher the resulting turbidity.Any particle within a sample that passes through a defined incident light source (often an incandescent lamp, light emitting diode (LED) or laser diode), can contribute to the overall turbidity in the sample. The goal of filtration is to eliminate particles from any given sample. When filtration systems are performing properly and monitored with a turbidimeter, turbidity of the effluent will be characterized by a low and stable measurement. Some turbidimeters become less effective on super-clean waters, where particle sizes and particle count levels are very low. For those turbidimeters that lack sensitivity at these low levels, turbidity changes that result from a filter breach can be so small that it becomes indistinguishable from the turbidity baseline noise of the instrument.This baseline noise has several sources including the inherent instrument noise (electronic noise), instrument stray light, sample noise, and noise in the light source itself. These interferences are additive and they become the primary source of false positive turbidity responses and can adversely impact the instrument detection limit. The subject of standards in turbidimetric measurement is complicated partly by the variety of types of standards in common use and acceptable for reporting purposes by organizations such as the USEPA and Standard Methods, and partly by the terminology or definition applied to them. In the 19th Edition of Standard Methods for the Examination of Water and Wastewater, clarification was made in defining primary versus secondary standards. Standard Methods define a primary standard as one that is prepared by the user from traceable raw materials, using precise methodologies and under controlled environmental conditions. In turbidity, Formazin is the only recognized true primary standard and all other standards are traced back to Formazin. Further, instrument algorithms and specifications for turbidimeters should be designed around this primary standard.Standard Methods now define secondary standards as those standards a manufacturer (or an independent testing organization) has certified to give instrument calibration results equivalent (within certain limits) to results obtained when an instrument is calibrated with user-prepared Formazin standards (primary standards). Various standards that are suitable for calibration are available, including commercial stock suspensions of 4,000 NTU Formazin, stabilized Formazin suspensions (StablCal™ Stabilized Formazin Standards, which is also referred to as StablCal Standards, StablCal Solutions, or StablCal), and commercial suspensions of microspheres of styrene divinylbenzene copolymer.
