อุปกรณ์วัด Multiparameter Photometer for Water Conditioning

The global distribution of freshwater resources varies greatly from region to region, and only 3% of global water resources are defined as freshwater. The definition of freshwater is water containing less than 1000 mg/L of dissolved solids, most often salt. In order to monitor the quality of water HI83208 was developed to be used for most common parameters: Ammonia detection in water treatment ... Read More »

อุปกรณ์วัด Multiparameter Photometer for Municipal Wastewater

With the beginning of the new millennium, water is becoming a strategic resource. Water has been and will continue to be a major factor for our survival, and the continuation of our way of life. Because of the limited resources of fresh water, careful use of it, as well as frequent reuse (after appropriate treatment) are requirements for sustainable development. HI ... Read More »

อุปกรณ์วัด Multiparameter Photometer for Industrial Wastewater

Pollution and excessive use seriously compromise the availability of fresh water around the world. In order to reduce the impact of industrial operators, there are numerous processes that can be used to clean up the wastewaters depending on the type and extent of contamination. Most wastewater is treated at an industrial scale at wastewater treatment plants, which may include physical, ... Read More »

อุปกรณ์วัด Multiparameter Photometer for Pulp and Paper Mills

Water is an indispensable medium for all stages of paper production. It is used for suspending and swelling, transport, the dissolution and the rebuilding of fiber bondings and more. Due to shrinking water resources, and subsequently, rising costs of available water supplies, more stringent environmental legislation has been put in place, strictly regulating industrial water consumption.  Amongst the many industries effected, ...

อุปกรณ์วัด Multiparameter Photometer for Power Plant Utilities

Ammonia levels are often tested in boiler feedwater and industrial waste. Chlorine is used to sanitize cooling towers and industrial equipment. Copper is often added to water to hinder growth of plankton and algae. Hydrazine has bactericidal properties and scavenges oxygen. Molybdenum is used as a corrosion inhibitor in cooling towers while phosphate can enter water streams due to boiler ... Read More »

อุปกรณ์วัด Multiparameter Photometer for Pools and Spas, Basic

Around the world, swimming pool and spa facilities welcome dozens, even hundreds of people on a daily basis.  A basic necessity of pool water treatment is to maintain the water in a safe and pleasant condition for the bathers. In order to achieve ideal water conditions, swimming pool water requires testing on a daily and sometimes hourly basis for disinfection residuals ... Read More »

อุปกรณ์วัด Nutrient Analysis Photometer for Greenhouses and Hydroponics, Basic

Deciding which fertilizer to use can be overwhelming, but with a bit of knowledge you can be sure your garden will get the right amount of nutrients it needs. The first question you’ll need to answer is, “What analysis do I need?” The analysis is actually three numbers you see usually at the middle or bottom of fertilizer packages (for ... Read More »

อุปกรณ์วัด Nutrient Analysis Photometer for Greenhouses and Hydroponics, Advanced

Nitrogen, phosphorus, and potassium (NPK) are often the first three factors considered when making recommendations to growers. Compared to the HI 83215, the HI 83225 provides control over three additional important growing factors: sulfur (most common as sulfates), calcium and magnesium. HI 83225 is designed for the hydroponics and greenhouse industries to measure seven nutrients commonly present in fertilizer enriched solutions. ... Read More »

อุปกรณ์วัด Multiparameter Photometer for Environmental Testing

HI 83206 is a multiparameter bench photometer dedicated to environmental testing. Critical environmental parameters such as pH, dissolved oxygen, nitrite, ammonia, chlorine and phosphorus or pollutants like chromium VI, nickel, silver and zinc can be monitored with this meter. This instrument measures 24 different methods, and has four measuring channels for a wide range of tests. The optical system of HI ... Read More »
