Hach Water Analysis

Hach has made water analysis instruments and reagents since 1947, and its methods are used in drinking water, wastewater and industrial water laboratories around the world. The instruments, reagents and standards are designed to work together, so a laboratory can run a test from sample to result with one system: digest the sample, read it on a spectrophotometer with a pre-programmed method, and check the instrument with matching standards.

CSI Labshop can supply Hach instruments, reagents and standards to laboratories and treatment plants in Malaysia. Tell us the parameters you test, your sample types and how many tests you run, and we will recommend a set-up and send a quotation.

Hach products we can supply

• Spectrophotometer: the DR1900 portable spectrophotometer (IP67, battery powered, more than 220 methods).
• Digestion: the DRB200 digital reactor block for COD, total nitrogen, total phosphorus and TOC vials.
• Reagents: TNTplus vial tests for COD, ammonia, nitrate, phosphate and total nitrogen, with a barcode on each vial that selects the method.
• Turbidity: the 2100Q portable turbidimeter and StablCal stabilized formazin standards to calibrate it.
• Meters: HQ series portable meters with Intellical probes for pH, conductivity and dissolved oxygen.
• Titration: the Titralab AT1000 series automatic potentiometric titrators.

How laboratories use Hach equipment

• Wastewater treatment plants digest COD vials in the DRB200 and read them on a spectrophotometer to report effluent quality.
• Drinking water plants check turbidity at each treatment stage with the 2100Q and calibrate it with StablCal standards.
• Industrial sites test boiler, cooling and process water where it is used, with the portable DR1900.
• Biological treatment is controlled with dissolved oxygen readings from an HQ meter and a luminescent DO probe.

How to choose

• COD and nutrients: pair a spectrophotometer with the DRB200 reactor and TNTplus vials.
• One or several parameters: a single-input HQ meter for one parameter; the HQ2200 or HQ4300 to measure several at once.
• Records: GLP records on the HQ4300 help with audits.

Frequently asked questions

Can you quote reagents and standards with the instrument?

Yes. Tell us the methods you will run, and we will include the reagents, standards and spare parts in the quotation.

Can you help us replace an older Hach instrument?

Yes. Send us the model you use now, and we will suggest its current equivalent.
