Measure oxygen concentration and percent saturation
- A great way to monitor a variety of common water quality factors without having to measure reagents
- Compare your readings to a handy color comparator chart printed right on the storage vial
- The six-way strips test: chlorine 0 to 10 ppm, pH 4 to 10, hardness 0 to 400 ppm, nitrate 0 to 50 ppm, and nitrite 0 to 10 ppm
- The five-way strips test: nitrate 0 to 200 ppm, nitrite 0 to 10 ppm, pH 6 to 9, alkalinity 0 to 240 ppm, and hardness 0 to 180 ppm
This accurate instrument features a large memory to hold up to 25 data sets with both dissolved oxygen (DO) and temperature readings. Oxygen level is displayed as percent saturation from 0 to 200% or concentration from 0 to 20.00 ppm (mg/l). Adjustable altitude compensation is 0 to 20,000' in 1,000' increments, and adjustable salinity compensation is from 0 to 50 ppt. It self-calibrates when turned on, includes auto-power off and a low battery indicator. Includes DO electrode, protective sensor cap, spare membrane cap, electrolyte, four 1.5 V SR44 W batteries, and a 48 neckstrap.
DO Range: 0 to 200%; 0 to 20.00 ppm. Resolution: 0.1%. Accuracy: ±2%; ±0.4ppm.
Temperature Range: 0 to 50 °C; 32 to 122 °F. Resolution: 0.1 °C/°F. Accuracy: ±1 °C/1.8 °F.
