Every Pool Professional Needs a PoolPro

The POOLPRO is an extremely reliable, precise, affordable, multi-parameter instrument for testing water quality in any pool or spa. If you own, operate or service a commercial pool or spa, you need a POOLPRO. It gives you instant, precise pH readings. Using colored strips or solutions can produce wildly varying, inaccurate results. pH is the most important factor in water balance and must be kept within a recommended range that also optimizes the sanitizer’s ability to work. POOLPRO is also a quick and easy way to stay on top of Total Dissolved Solids (TDS). TDS is another factor in water balance and profoundly impacts water taste and bather comfort. In a commercial pool or spa you must carefully monitor and control TDS on a regular basis to maintain acceptable levels. This prevents having to eventually drain and refill the pool or spa with new, lower TDS water — which is not only costly, but may be illegal.

The POOLPRO now features an LSI calculator that makes it easy to analyze the scaling nature of water in the lab or in the field. Using a calcium carbonate saturation index algorithm developed by Dr. Wilfred Langelier in 1936, the calculator computes the saturation index of a sample based on measured and inferred values for pH, temperature, hardness and alkalinity. You can then change any of these values in user adjust mode to analyze the effect of the change on water balance. User mode also allows you to input measured values for alkalinity and hardness as determined by other independent testing for a precise saturation index value. Saturation index values are generally interpreted as follows: An index between -0.5 and +0.5 indicates balanced water An index of more than +0.5 indicates scale-forming water An index below -0.5 indicates corrosive water.

Within the LSI Calculator is a Hardness calculator that allows you to select either ppm or grains of hardness units for saturation index calculation. The hardness unit conversion is based on the following equivalency: 17.1 ppm (mg/L) = 1 grain. The hardness range is limited to 0.0 - 1710 ppm and 0.0 - 100 grains of hardness in the POOLPRO.
