Ion Specific Colorimeters (Photometers)

Digital Colorimeters for Ammonia, Nitrate, or Nitrite Nitrogen allow you to test water quality directly in ppm NH4, NO3, or NO2. Determine levels in soil or compost using extraction/filtration.

Portable Field Meters With Laboratory Accuracy

Simple reagents are added to each sample to produce a color change that represents the concentration of the measured parameter. Each meter reads this change in color with a silicon photocell and shows the value of the parameter on the large LCD with lab grade accuracy from the powerful microprocessor.
