Frequently Asked Questions

Q. What is the Hach DR1900 Portable Spectrophotometer used for?

A.The Hach Spectrophotometer is used to measure the concentration of chemical parameters in water and wastewater samples. It operates across a visible wavelength range of 340 to 800 nm and comes pre-loaded with over 220 methods for testing chlorine, ammonia, nitrate, phosphate, iron, manganese, turbidity indicators, BOD, COD, and many more parameters. Professionals use it in drinking water treatment plants, industrial ETP monitoring, environmental field surveys, aquaculture farms, food processing quality control, and university research laboratories across Bangladesh.

 

Q. Is the Hach DR1900 waterproof? Can I use it in rain or near water bodies?

A. Yes. The Hach DR1900 carries an IP67 waterproof and dustproof rating, which means it is fully protected against dust ingress and can withstand submersion in up to 1 metre of water for 30 minutes. Therefore, field technicians can use the DR1900 confidently in rainy conditions, near rivers, lakes, wetlands, and in dusty industrial environments without risking damage to the instrument.

 

Q. How many test methods does the DR1900 have pre-programmed?

A. The Hach DR1900 Portable comes factory pre-loaded with over 220 Hach and Hach/Lange water quality test methods — the largest number of any portable spectrophotometer currently available on the market. These methods cover the most commonly tested parameters in drinking water, wastewater, industrial process water, environmental monitoring, and aquaculture. Additionally, users can create and save unlimited custom methods through the instrument’s intuitive interface.

 

Q. Does the DR1900 support EPA-approved water testing methods?

A. Yes. Several of the pre-programmed methods available on the Hach DR1900 are EPA-approved for regulatory water quality testing. EPA-approved reagent kits are listed in the official Hach Lab Applications Reference Guide, which is available from ASTZBD upon request. These methods make the DR1900 suitable for use in compliance testing, regulatory reporting, and environmental impact assessment work where internationally recognised analytical standards must be followed.

 

Q. How does the DR1900 data logger work? Is it GLP compliant?

A. The Hach DR1900 stores up to 500 measured values in its internal data logger. Each stored result is automatically tagged with the measurement result, date, time, Sample ID, and User ID. This data format complies with Good Laboratory Practice (GLP) documentation standards, making the DR1900 suitable for regulated and auditable laboratory environments. Data is transferred from the instrument to a computer through the USB mini port for record keeping, reporting, and analysis.
