Hanna HI98304 DiST 4 Waterproof EC Tester
The Hanna HI98304 DiST 4 is a rugged and reliable pocket-sized tester designed to provide quick and accurate readings of Electrical Conductivity (EC). As part of the world-renowned DiST family, this tester has become an industry standard for its durability and ease of use in both field and laboratory settings.
Advanced Graphite Sensor Technology
Unlike standard testers that use stainless steel pins, the DiST 4 features an amperometric graphite electrode. Graphite sensors provide better repeatability because they do not oxidize, ensuring the distance and surface area between the pins remain constant over time. This design allows for more dependable results and a longer lifespan for the probe.
Automatic Temperature Compensation (ATC)
Conductivity measurements are highly sensitive to temperature variations. The HI98304 includes an exposed temperature sensor that provides fast response times. The device automatically compensates for temperature changes from 0.0 to 50.0°C (32.0 to 122.0°F), ensuring your EC readings are accurate regardless of the environment.
User-Friendly Interface and Large LCD
The tester features a large, multi-level LCD that displays both the EC and temperature readings simultaneously. The display also includes helpful indicators for calibration status and stability. Operation is simplified with just two buttons: one for turning the meter on/off and another for entering the automatic calibration mode.
Versatile Applications
The DiST 4 is widely used across a variety of industries to monitor water quality and nutrient levels. It is an essential tool for:
- Hydroponics & Agriculture: Optimizing nutrient solutions for plant growth.
- Water Treatment: Monitoring drinking water, reverse osmosis systems, and wastewater.
- Industrial Use: Cooling towers and the printing industry.
- Aquaculture: Maintaining ideal conditions for fish and aquatic life.
- Laboratories: General-purpose conductivity testing.
Built-In Durability & Efficiency
Designed to withstand harsh environments, the HI98304 features a waterproof casing. It is powered by a CR2032 Li-ion battery, providing approximately 250 hours of continuous use. To preserve battery life, the tester includes an auto-off feature that can be set to 8 minutes, 60 minutes, or disabled entirely.
