HI 208 is an all-in-one pH meter designed to meet the classroom environment with features such as a built-in beaker holder, beaker-top electrode holder and 3-in-1 pH and temperature sensor. HI 208 is also equipped with an internal magnetic stirrer activated from the instrument's keypad. This instrument also features an extended pH range of -2.00 to 16.00, dual-level LCD with icons for stability and buffer recognition, automatic pH calibration with 2 sets of memorized buffers, Celsius or Fahrenheit temperature range and automatic temperature compensation. In the classroom, this compact unit reduces "clutter" and utilizes a minimal amount of space on the desktop.
Switch to battery power and the instrument can be taken outside the classroom for field studies. The units' small footprint enables HI 208 to be used in places usually not suitable for large, multi-unit set-ups. When lab time is over, the instruments are easily cleaned and can be placed out of the way - right away. HI 208 operates on either the 12 Vdc adapter or batteries.
