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

Hanna Instruments - The world’s leading manufacturer of electro-analytical instruments has the right solution to solve the problem of measuring water parameters in an easy, inexpensive and accurate way. Ion specific meters are a simpler alternative to Ion Selective Electrodes and time-consuming chemical test kits.

Specifications: 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.
