Omega Engineering has introduced the lightweight HHWT-13 series of handheld dip strip photometers, a green and cost-effective alternative to testing water for chemicals. Instead of using a 10-mL water sample, this CE-compliant product uses a 4-mL water sample, which uses up to 60% les chemical per test. It features three-button control, 140 test memory, and an automatic countdown test time.
