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.
Automatic Shut-off
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
HI99300 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 to 3999 µS/cm; TDS measurements range from 0 to 2000 ppm.
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.
Portable Design
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 HI99300 Low 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.
Two-Ring Probe
The HI763063 is a two-ring probe that comes with the HI99300, offering an accurate solution for low 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 Low Range EC/TDS Meter is equipped with everything you need for successful testing right out of the box.
1413 ?S/cm and 1382 ppm 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.
