The HI991001 meter features a large multi-level display that displays pH and temperature measurements simultaneously with 0.01 pH resolution and ± 0.05 pH accuracy.
Indicators for calibration status, stability and even tutorial messages can be shown on the display.
The HI991001 is equipped with many advanced features found on more expensive portable instruments, including automatic calibration, standard solution recognition, and temperature compensation.
The battery level is displayed when the instrument is turned on.
Main features
Waterproof- Designed to float if accidentally dropped into a tank.
Extended pH range- PH range from -2.00 to 16.00 pH.
Two-point automatic calibration
- Automatic one or two point calibration with two sets of selectable standard solutions (4.01, 7.01 and 10.01 or NIST 4.01, 6.86 and 9.18).
Automatic temperature compensation- All measurements are compensated for temperature variations.
- The temperature is displayed in ° C or ° F along with the pH value.
Stability indicator- The meter displays a symbol (clock) which disappears when the reading is stable.
HOLD button- Freezes the stable measurement on the display to allow the user to record it.
BEPS (Battery Error Prevention System)- The meter turns off automatically if the battery is low and an accurate measurement cannot be obtained.
Percentage% of battery at power on Low battery indicator- When the battery charge is less than 5%, the battery symbol flashes on the display to indicate that the battery is low.
Automatic shutdown- The meter turns off automatically after 8 minutes of inactivity to save battery power.
