  • Auto-Off function conserves battery power. The unit shuts off automatically after 20 seconds
  • Dual range; measures from 0 - 999 ppm, with a resolution of 1 ppm. From 1,000 to 9,990 ppm, the resolution is in 10 ppm increments, indicated by a blinking 'x10' image
  • Factory calibrated, our meters are calibrated with a 342 ppm NaCl solution. Meters can be recalibrated with a mini-screwdriver
  • Comes equipped with 1/4 inch Mur-lok® quick connect T-fittings. Also available with 3/8" or 1/2" fittings
  • Installs quickly and easily
