I found the price on the hach reagents aren’t that bad of a priceAnother option is to buy non-Hach reagents. See if the Hach part number you want is listed here:
Then search for the corresponding Lovibond part number here:
Lab Equipment, Supplies, Instruments & Tools | Nova-Tech International
Nova-Tech International provides high quality lab equipment and general lab supplies. Metering Pumps, thermometers, hydrometers and much more.www.novatech-usa.com
They don't charge sales tax or, to the best of my knowledge, $50 hazmat fees like Hach. Lovibond reagents are drop shipped from the manufacturer in FL.
For example, if you want the Hach ammonia test part # 2668000 the Lovibond part # is 535500.
