Introduction to the HI991300 Meter
The HI991300 is a versatile, portable multiparameter meter produced by Hanna Instruments. Moreover, it is fully waterproof with an IP67 rating, ensuring durability in various environments.
Core Measurement Capabilities
This device excels at measuring pH, conductivity (EC), total dissolved solids (TDS), and temperature all at once using a single probe. For instance, the low-range model is particularly suited for applications such as hydroponics, greenhouses, and water treatment. Additionally, it works well in environmental monitoring, wastewater management, and boilers or cooling towers.
Detailed Specifications Breakdown
Here are the key specs in a structured format:
- pH: It offers a range of 0.00 to 14.00 pH, with ±0.01 accuracy and 0.01 resolution.
- EC (Low Range): Ranges from 0 to 3999 µS/cm, featuring ±2% full-scale accuracy and 1 µS/cm resolution.
- TDS: Covers 0 to 2000 ppm (mg/L), and users can select a conversion factor of 0.45 or 1.00.
- Temperature: Spans 0.0 to 60.0°C (32.0 to 140.0°F) with 0.1°C resolution. Furthermore, it includes automatic temperature compensation (ATC) for both pH and EC/TDS readings.
Calibration is straightforward too. Specifically, it supports automatic one- or two-point pH calibration, along with single-point EC calibration. In addition, there’s a “Quick Cal” mode that speeds up combined pH/EC calibration.
Probe Design and User-Friendly Features
The meter comes equipped with the HI12883 replaceable 3-in-1 probe, which integrates pH, EC/TDS, and temperature sensing. Besides, this probe has a built-in amplifier to reduce electrical noise interference, and its body is made of tough polypropylene for longevity.
On the design side, the unit is lightweight and slim. It operates using just two buttons, which simplifies usage. Moreover, a large multi-line LCD screen displays all readings simultaneously for quick reference.
Variants and Further Resources
For higher conductivity needs, consider the HI991301 variant. This model extends EC to 20.00 mS/cm and TDS to 10.00 ppt, making it ideal for more demanding samples.
