The meter easily fits in the palm of your hand and the bottom probe connection ensures the electrode cable doesn’t get in the way. The large, multi-level LCD displays the primary reading, temperature, and calibration guides simultaneously. Symbols and messages on the LCD indicate meter status and guides users through operations.
Automatic Temperature Compensation – Since temperature has such a dramatic effect on conductivity and TDS readings, having a meter that offers temperature compensated readings is invaluable. The probe of the HI99301 features a built-in temperature sensor that automatically accounts for the effects of temperature in the range of 0 to 60°C (32 to 140°F).
Adjustable Temperature Compensation Coefficient – The temperature compensation coefficient, also known as β, is adjustable from 0.0 to 2.4%/°C with 0.1% intervals; this factor corrects the reading a set percentage % for each degree Celsius change in the sample.
Automatic Calibration – The HI99301 can be automatically calibrated at one point in a standard EC or TDS solution. A 12.88 mS/cm standard is used for EC calibration, which will automatically calibrate TDS readings. However, if the meter is in TDS mode and set to 0.5 conversion factor, a direct calibration in 6.44 ppt TDS calibration solution can be used.
Battery Error Prevention System (BEPS) – The Battery Error Prevention System detects when the batteries become too weak to ensure reliable measurements.
Instability Indicator – The HI99301 displays a clock tag that will disappear when a reading has achieved stability.
