Will these work with the LaMotte 1200 colorometer?

These items likely will not. They are based on a dye developed specifically for the calibration curves in Hach products. It is highly unlikely that LaMotte will have the same calibration curves and ranges built into their instrument to allow accurate readings of the Gel Dye to occur.

Will this work with the dr3900?

Hello, The high range DPD Chlorine SpecChecks can be used with high range chlorine programs on the DR3900. Please note that these SpecChecks will only work with high range programs and they will not work with low range or mid range programs. The high range programs have an upper range limit of 10 mg/L. I hope you find this information helpful. Thank you for contacting Hach Technical Support Jody H

Will These items work with DR 300 test kit

Depending on which DR300 model you have, this high range set of SpecCheck standards may work. This set only works with the high range procedure. There is a DR300 model that is LR/HR and there is one that is MR/pH. These will only work with the LR/HR model, on the high range setting.

What is the expiration date? Ours have expired and looking to find the longest lasting expiration as possible

I ordered mine about 1 1/2 months ago and the expiration date on them are Feb 2019. I have both the HR and the LR standards.
