The new, lightweight HHWT-13 series of handheld dip strip photometers are a more “green” and cost effective alternative to testing water for cyanide, iron, ammonia, phosphate, pH (5 to 10) sulfide, fluoride, chloride and quarternary ammonia. Instead of using a 10 ml water sample, this CE compliant product uses a 4 ml water sample, which uses up to 60 percent less chemical per test. It features simple 3-button control, 140 test memory and an automatic countdown test time. This product is ideal for wastewater treatment and in all industries which require the monitoring of their process pH.
