Portable Multiparameter pH/EC/ISE/Turbidity/DO Meter with GPS and Autonomous Logging Probe - HI98394
Our Portable Multiparameter pH/EC/ISE/Turbidity/DO Meter (HI98394) monitors up to 14 different water quality parameters (7 measured and 7 calculated). Test for pH, ORP, turbidity, dissolved oxygen, conductivity, chloride, nitrate, ammonium, temperature, and more, all-in-one meter. Each parameter is fully configurable.
Start testing immediately in any environment! This meter arrives in a protective, heavy-duty carrying case with all required testing supplies and is easy to setup. Simple and intuitive, users can choose to enable on-screen tutorials that provide step-by-step guidance with sensor preparation, installation, maintenance, and calibration.
Tailor this meter to fit your testing requirements and choose from several cable length options. Our meter is enclosed in an IP67-rated waterproof casing and can be immersed in water at a depth of 1m for up to 30 minutes. The accompanying IP68-rated probe is fully sealed against water and dust and can withstand continuous immersion in water.
- Handheld and durable, take stable and accurate readings conveniently on the go in the lab or field
- Equipped with a weighted, autonomous logging probe that is perfect for analyzing multiple water quality parameters at different depths
- Maintain data integrity with record, logging, and transfer capabilities. Built-in GPS enables users to track the location and coordinates of measurement data as well. Easily download log files via a USB or PC connection

Keep track of measurements precisely with GPS
Our Portable Multiparameter Meter features an internal 12 channel GPS receiver and antenna that calculates its position to track locations along with measurement data. The GPS tracks your location using satellites within 30 ft (10 m), so you can be sure that you return to the same exact location for repeated measurements. All GPS data can be customized to meet specific requirements.
GPS features overview:
- Display up to 10 parameter measurements along with the GPS coordinates on the meter screen
- GPS signal strength is visible
- Logged data is embedded with GPS coordinates
- GPS status screen will list your current position and the number of satellites
- Users can assign a custom name to GPS coordinates for easy record keeping
- Shows the actual distance and how far you are from nearby saved locations
- Your most recent position is recorded with a time stamp in case the GPS signal is lost
