Lightweight HHWT-13 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% less chemical per test. It features simple 3-button control, 140 test memory and an automatic countdown test time. This product is suitable for wastewater treatment and in all industries which require the monitoring of their process pH. Omega
