The DULCOTEST Model DT1B is a professional-grade, portable photometer designed for rapid and precise on-site water analysis. Manufactured in Germany by ProMinent, a global leader in fluid handling technology, this instrument is built to the highest standards of quality and reliability.
It is a versatile multi-parameter device, allowing users to measure several critical water quality parameters with a single, robust instrument.
Key Features & Overview
-
Manufacturer: ProMinent GmbH, Germany.
-
Model: DT1B (Portable Photometer).
-
Origin: Made in Germany, ensuring high engineering and manufacturing quality.
-
Primary Use: On-site testing of water and disinfectant levels in various applications.
Measured Parameters
The DT1B is capable of measuring the following key parameters, which are essential for water treatment, disinfection control, and pool & spa maintenance:
-
CL2: Free Chlorine – The most critical parameter for measuring the active disinfecting power in water.
-
BR2: Bromine – An alternative disinfectant to chlorine, commonly used in spas and hot tubs.
-
CIO2: Chlorine Dioxide – A powerful disinfectant used in drinking water, food & beverage processing, and industrial water systems.
-
O3: Ozone – A strong oxidant and disinfectant used in various water treatment processes.
-
PH: pH Value – Measures the acidity or alkalinity of the water, which is crucial for disinfection efficiency and water balance.
-
CYA: Cyanuric Acid – A stabilizer used in outdoor swimming pools to prevent chlorine from being broken down too quickly by sunlight.
Technical Description & Operation
-
Photometric Principle: The DT1B operates on the principle of photometry. A water sample is placed in a reusable cuvette. A pre-measured reagent tablet (DULCOTEST-specific) is added, causing a color change proportional to the concentration of the parameter being measured.
-
Measurement: The cuvette is then inserted into the photometer. The device passes a specific wavelength of light through the sample and measures the amount of light absorbed. This absorbance is directly correlated to the concentration, which is then displayed digitally on the screen.
-
Portability: Its compact, rugged, and self-contained design makes it ideal for use in the field, at a plant, or by a poolside. It is typically powered by long-life batteries.
-
Ease of Use: The device is designed for simplicity, with clear buttons for parameter selection and an easy-to-read display, requiring minimal training for accurate operation.
Key Advantages
-
Multi-Parameter: One device replaces several single-parameter testers, saving cost and simplifying your toolkit.
-
High Precision: Offers more accurate and reliable results than simple visual test kits (test strips or comparator blocks).
-
German Engineering: Known for durability, precision, and long-term reliability.
-
On-Site Results: Provides immediate data for quick decision-making regarding chemical dosing and process control.
Typical Applications
The DULCOTEST DT1B is used across a wide range of industries and settings, including:
-
Swimming Pool & Spa Maintenance: For balancing chlorine/bromine, pH, and cyanuric acid levels.
-
Drinking Water Treatment: To monitor disinfectant residuals like chlorine and chlorine dioxide.
-
Food & Beverage Industry: For disinfectant control in process water.
-
Cooling Towers & Industrial Water Systems: Monitoring biocide levels (e.g., bromine) and pH.
-
Municipal Water & Wastewater Treatment.
