Once in calibration mode submerge the probe in 1382 ppm calibration standard. The use of graphite also reduces the polarization effect common with amperometric testers that use two stainless steel pins.Ĭalibration is performed by pressing the dedicated calibration button. TDS readings are performed by an amperometric graphite electrode that resists oxidation, providing better repeatability in measurements. The battery percent level is displayed at start up alerting the user to the remaining battery power that is available. The LCD screen has stability and calibration tag indicators. Temperature can be set to display in ℃ or ℉. An exposed temperature sensor allows for rapid automatic temperature compensated TDS measurements. The TDS range of the HI98301 is from 0 to 2000 ppm.

Portable High Range EC/TDS Meter - HI99301Ĭall if accurate shipping time is requiredĪutomatic, with b selectable from 0.0 to 2.4 %/ ☌ in 0.1 increments Instability Indicator - The HI99301 displays a clock tag that will disappear when a reading has achieved stability. 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.īattery Error Prevention System (BEPS) - The Battery Error Prevention System detects when the batteries become too weak to ensure reliable measurements. A 12.88 mS/cm standard is used for EC calibration, which will automatically calibrate TDS readings. 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☌ (32 to 140☏).Īdjustable Temperature Compensation Coefficient - The temperature compensation coefficient, also known as β, is adjustable from 0.0 to 2.4%/☌ with 0.1% intervals this factor corrects the reading a set percentage % for each degree Celsius change in the sample.Īutomatic Calibration - The HI99301 can be automatically calibrated at one point in a standard EC or TDS solution. The HI99301 has an adjustable TDS factor from 0.45 to 1.00 with 0.01 intervals, allowing users to choose the conversion factor that is the most appropriate for their particular solution.Īutomatic 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 ratio between the two parameters depends on the solution being measured. EC measurements range from 0.00 to 20.00 mS/cm TDS measurements range from 0.00 to 10.00 ppt.Īdjustable TDS Factor - The TDS value in aqueous solutions is directly proportional to conductivity. Users can easily switch between measurement modes with a simple press of the MODE button. Two Measurement Modes - HI99301 offers two measurement modes: EC and TDS. The probe features a built-in temperature probe to allow for temperature compensated readings. Two-ring Probe - The HI763063 is a two-pole probe that comes with the HI99301, offering an accurate solution for high range EC and TDS readings.

Symbols and messages on the LCD indicate meter status and guides users through operations.

The large, multi-level LCD displays the primary reading, temperature, and calibration guides simultaneously. 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 probe also features a built-in temperature sensor to allow for Automatic Temperature Compensation from 0 to 60☌ (32 to 140☏). The HI763063 EC/TDS probe is a two-ring sensor that resists clogging and is easy to clean. It measures high range conductivity in mS/cm and TDS in ppt. The portable, waterproof HI99301 EC/TDS and temperature meter is suitable for use in applications as diverse as wastewater treatment, reverse osmosis, and HVAC.
