Leitfähigkeit/TDS/°C-Handmessgerät bis 20,00 mS/cm - HI99301
Designed to bring simplicity to testing in manufacturing and environmental industries, the HI99301 High Range EC/TDS Meter is designed for measurements in brackish and high ionic strength water applications. The specialized HI763063 probe features EC/TDS and temperature in one convenient, rugged probe for high range EC measurements from 0.00 to 20.00 mS/cm and TDS measurements from 0.00 to 10.00 ppt.
- ±2% EC/TDS Accuracy
- Comes with all the necessary solutions and batteries- everything you need to get started measuring right away.
- Perfect for water quality testing in manufacturing and environmental industries.
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.
Two-ring Probe - The HI76306 is a two-ring probe that comes with the HI99301, offering an accurate solution for high range EC and TDS readings. The probe features a built-in temperature probe to allow for temperature compensated readings.
Two Measurement Modes - HI99301 offers two measurement modes: EC and TDS. Users can easily switch between measurement modes with a simple press of the MODE button. EC measurements range from 0.00 to 20.00 mS/cm; TDS measurements range from 0.00 to 10.00 ppt.
Adjustable TDS Factor - The TDS value in aqueous solutions is directly proportional to conductivity. The ratio between the two parameters depends on the solution being measured. 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.
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.
Low Battery Indicator
The included batteries provide 500 hours of continuous use. When the battery level is below 10%, a warning symbol will blink to indicate low battery condition. When low battery power may affect your results, the meter will shut down to avoid erroneous readings caused by low battery level.
The auto-off feature can be set to shut the meter off at 8 or 60 minutes, or it can be disabled so that the meter continuously stays on. The auto-off feature prolongs battery life for peace-of-mind and energy savings if the meter is accidentally left on.
Two Measurement Modes
HI99301 offers two measurement modes: EC and TDS. Users can easily switch between measurement modes with a simple press of the MODE button. EC measurements range from 0.00 to 20.00 mS/cm; TDS measurements range from 0.00 to 10.00 ppt.
Built to be Durable
Designed to withstand the knocks, drops, and spills of real life, the new IP67 body ensures top performance in any environment. These meters are protected against dust and water intrusion from any direction.
Made to fit comfortably in your hand for on-the-go testing, the multilevel LCD display provides at-a-glance readings of EC/TDS and temperature from any angle and dual button operation streamlines the testing process for any user.
Quick Connect Probe
A Quick Connect DIN connector makes attaching and removing the probe simple and easy. The rubber coating protects the cable and provides a water-tight seal without twisting.
Your measurements require detailed attention; so should your electrode. The HI99301 High Range EC/TDS Meter features a replaceable HI763063 probe that has been carefully designed for use in applications as diverse as wastewater treatment, reverse osmosis, and HVAC.
The HI763063 is a two-ring probe that comes with the HI99301, offering an accurate solution for high range EC and TDS readings.
Built-in Temperature Probe
An integrated temperature probe ensures fast, accurately compensated readings even during sudden temperature fluctuations.
We believe that buying a meter should be simple. Your High Range EC/TDS Meter is equipped with everything you need for successful testing right out of the box.
12880 μS/cm and 6.44 ppt Conductivity Standard (1 each)
When performing an EC/TDS calibration it is important that the correct standards are used. We include some starter standards to get you going. The single-use sachets are individually sealed so you use fresh buffer each time you calibrate.
