In the United States, drinking water quality is regulated by state and federal codes in place to set maximum contaminant levels (MCLs) for many pollutants. These same regulations require utilities to publish highly-accurate consumer confidence reports for their customers. Therefore, the smallest amounts of such parameters need to be detected on a regular basis. Heyl Brothers products are designed to analyze various parameters needed to ensure the safe and accurate treatment of drinking water.
One example is the Testomat 2000® DUO. The online instrument simultaneously monitors alkalinity and water hardness in drinking water supplies on a quantity- or time-controlled basis. The instrument allows for a separate, quality-dependent softening unit to be installed with the use of external control units (e.g., Heyl Brothers' Softmaster® MMP1 or Softmaster® MMP2). The instrument measures inlet and outlet hardness and can be used in two circuits with two different types of hardness or alkalinity. Other Testomat 2000® models also measure other parameters such as chlorine, hexavalent chromium, iron, or sulfite.
The Testomat 2000 DUO® has many advantages and requires considerably low maintenance. The device is operated and programmed with the use of a background-illuminated plain text display with quick menu navigation. Service addresses, maintenance intervals for maintenance requests and other settings are all programmable features included in the instrument. Plant operators are able to extend the operating period of the instrument with use of the 500-mL-sized storage bottle for the preferred reagent based on the desired parameter to be measured. Another advantage includes internal and external error documentation along with adjustable limit values. High accuracy of measurement is ensured with its internal piston-dosing pump.
In addition to successfully measuring two separate parameters simultaneously (e.g., two measuring ranges for water hardness or water hardness and carbonate hardness), the analyzer also includes a data logger, optional booster pump, and two-line LCD display for text presented in English and Mandarin with an easily-readable, menu-driven operating interface. The system's approximate weight is 9.5 kg along with dimensions of 380 x 480 x 280 mm. Further, its power consumption is 30 VA, and its operating pressure is 0.3-8 bar, with a water temperature of 0–40°C (50–104°F) and an ambient temperature of 10–45°C (50–113°F).
The instrument's range of application includes but is not limited to drinking water supplies (various types of alkalinity and water hardness), osmosis plants (hardness and chlorine), electroplating (chromate and chrome VI), de-ironing plants (iron), large-scale industry steam boilers and cooling towers (water hardness, polyamines and phosphate), and swimming pools (free and total chlorine).
