Hanna HI991301 Portable High Range pH EC TDS Meter
Portable Waterproof pH/EC/TDS Meter (High Range)
Designed to bring simplicity to testing, the HI991301 pH/EC/TDS Meter is designed specifically for use in manufacturing and environmental testing protocols. The specialized electrode combines 3 sensors in a single rugged probe body featuring a polypropylene body, integrated temperature sensor, and cloth junction.
- 3-in-1 probe measures pH, EC/TDS, and temperature.
- Comes with all the necessary solutions and batteries- everything you need to get started measuring right away.
- Perfect for water quality testing.
Low Battery Indicator
The included batteries provide 1400 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.
Probe Condition
An on-screen indicator provides visual confirmation that your probe is working at its best.
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.
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 pH 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.
