Waterproof pH TDS Tester Hanna Instruments HI98130 Meter

Description

Product Overview

The Hanna Instruments HI98130 is a rugged, waterproof handheld instrument designed to provide precise pH, electrical conductivity (EC), total dissolved solids (TDS), and temperature measurements in a single, compact unit. Engineered for durability, the device features an IP68‑rated enclosure that protects internal electronics from immersion, dust, and accidental drops, making it suitable for fieldwork, greenhouse environments, and laboratory benches alike. The high‑range EC/TDS sensor can accurately measure conductivity up to 200 mS/cm, covering the full spectrum of water‑quality applications from nutrient‑rich hydroponic solutions to municipal water testing. A replaceable stainless‑steel pH electrode with a snap‑in connector ensures reliable performance over extended service life, while the graphite conductivity probe eliminates salt‑deposit contamination, preserving measurement accuracy even after repeated use. Power management is optimized through a clear battery‑life indicator displayed at startup, an automatic shut‑off function that conserves energy during inactivity, and a low‑battery alert that prevents unexpected shutdowns. The instrument operates on four AA batteries, which are supplied in the package for immediate deployment.

Usage

Designed with versatility in mind, the HI98130 serves a broad range of professional and hobbyist users. Hydroponic growers rely on its rapid pH and EC/TDS readings to fine‑tune nutrient solutions, ensuring optimal plant health and yield. Agricultural technicians employ the meter to monitor irrigation water quality, detect salinity issues, and verify compliance with regional water‑use regulations. Environmental scientists and water‑quality laboratories use the device for on‑site sampling of rivers, lakes, and wastewater streams, benefiting from its waterproof construction and quick‑response sensors. The built‑in temperature probe provides real‑time thermal data, which is essential for correcting conductivity readings and understanding solubility dynamics in various media. Because the instrument is lightweight (approximately 300 g) and ergonomically shaped, users can comfortably conduct prolonged field surveys, handheld measurements, or bench‑top analyses without fatigue. The intuitive interface, featuring a single LCD screen and straightforward navigation keys, reduces training time and allows new users to obtain reliable data within minutes of first use.

FAQ

What types of solutions can the HI98130 accurately measure?

The instrument is calibrated for a wide range of aqueous solutions, from low‑conductivity distilled water to high‑conductivity nutrient mixes used in hydroponics. Its EC/TDS range of 0‑200 mS/cm allows precise monitoring of both dilute and concentrated solutions, making it suitable for agricultural irrigation, laboratory research, and industrial process control.

How often should the pH electrode be calibrated?

For best results, calibrate the pH electrode at least once a day when performing critical measurements, or whenever the temperature changes significantly (more than 5 °C). Hanna Instruments provides calibration buffers (pH 4.0, 7.0, and 10.0) that can be used with the built‑in calibration routine to ensure accuracy within the specified ±0.01 pH tolerance.

Can the device be used in outdoor field conditions?

Yes. The IP68 waterproof rating protects the meter from immersion up to 1 m for 30 minutes, and the rugged ABS housing resists drops and impacts. The automatic shut‑off and low‑battery alerts further enhance reliability during extended field campaigns, while the included battery pack provides up to 500 measurements on a single set of AA cells.

What maintenance is required for the conductivity probe?

After each measurement session, rinse the graphite probe with distilled water and gently wipe it dry with a lint‑free cloth. Because the probe is made of graphite, it does not accumulate salt deposits like metal probes, but periodic cleaning ensures the longest possible service life. If the probe shows a persistent drift, replace it with the spare unit supplied in the accessories kit.

Is there a warranty or service plan available?

Hanna Instruments offers a standard two‑year limited warranty covering defects in materials and workmanship. Customers can also purchase extended service plans that include annual calibration, priority technical support, and on‑site repair options, providing peace of mind for critical applications.
