HI 98201 ORP Tester with ORP Range up to ±999 mV
Oxidation is a process by which a molecule or ion loses electrons. This occurs most readily in water treatment as well as pool and spa maintenance where an oxidizer, such as chlorine, is added to the water to destroy contaminants. The higher the ORP value, the greater the sanitizing power of your water. HI 98201 ORP tester can provide a valuable indication of water quality.
HI 98201 ORP is a unique hand-held tester developed for quick and affordable tests. This tester utilizes a platinum electrode and HANNA®' unique renewable cloth fiber junction, that can be pulled out when clogging occurs, reactivating the reference and restoring the electrode.

HI 98202 (pNA) Economical Pocket Tester to Measure Water Hardness
The pNa is an easy-to-use and inexpensive instrument for determining water hardness/softness. The hardness of water is due to the presence of magnesium and calcium. These make washing difficult, waste soap and create unpleasant scum and scale deposits. With a zeolite system, the calcium and magnesium ions are substituted on a one-to-one basis with sodium ions from a conditioning resin. Once all the sodium ions are exhausted, the resin has to be regenerated. This is currently determined by estimating the volume of water that goes through the softener and guessing when to change the resin!
Even though this may work in some cases, it fails in most since the sodium content of feed water is never constant. As a result, either the resin is regenerated too early, and waste resources, or too late, risking damage due to scaling. With the pNa, you can measure the sodium content of feed water and exit water in seconds. When the resin is exhausted of sodium, there will be no exchange and the pNa will read the same value at the two ends. Only then should the resin be changed. pNa takes guess work out of resin regeneration!
| Range | pNa | 0.0 to 3.0 pNa (23 to 0.023 g/L Na+) |

HI 98203 Pocket Tester to Measure the Salt Content of Water
Worldwide, fish farming has made great strides in the past two decades with aquaculture becoming the prime source for quality seafood in an ever growing industry. As the methods and products keep changing, one crucial factor remains the same: the necessity for salinity testing of the water. The main component of salt in seawater is sodium chloride.
The SALINTEST can help you monitor the concentration of sodium chloride, assuring high surety in aquaculture systems. SALINTEST is also ideal for marine fish tanks and aquariums.
Instruments for measuring salinity of seawater currently available on the market are cumbersome and difficult to use. HANNA® has re-engineered this compact salt tester with a more durable, ergonomic casing and a larger LCD. Besides applications in aquaculture, SALINTEST is also ideal for checking salt concentrations in live fish storage tanks, tropical fish aquariums, refrigerated storage and oceanographic investigations.
