NA-T2012 Digital Handheld Free Chlorine Meter

Free Chlorine Handheld Spectrophotometer

Stock Status: In Stock


Water free chlorine detection requirements have been implemented for many years, Taiwan NIEA also announced "Free Chlorine in Water Test Standard Method - by Spectrophotometer", as a standard for free chlorine in the water.

NA-T2012 digital free chlorine and pH detector, the original standard method to further simplify the same time. And the cost is only 1/10 of a desktop spectrophotometer. The handheld spectrophotometer NA-T2012 significantly reduce your detecting costs. Moreover, it uses dual wavelengths light source to detect and improve the test accuracy (range 0.00 ~ 2.00PPM, accuracy 0.01 ppm). At the same time, the phenol red indicator can also be used to determine the pH of the sample water (range 6.0 to 8.6 pH 0.1 pH).

The instrument uses the standard 1cm sample cuvette, and Taiwan NIEA standard method also suggest the same cell.


  • Easy to read the result in and digital digital display!
  • Small and easy to carry.
  • Use highly safe DPD reagent (residual free chlorine) and phenol red indicator (hydrogen ion pH)
  • Small package DPD reagent is one-third of the cost of traditional testing
  • Power for selection, either battery or AC adapter


Measuring tap water, swimming pool water, kitchen drinking water, purified water tank, free chlorine concentration from sewage, and hydrogen ion concentration (pH)
