Waterproof Portable pH and Temperature Meter

Simplify your pH and temperature measurements with the HI991001 portable meter, built for durability and dependable readings in diverse applications.

Confident Probe Status

A clear visual indicator on the display confirms that your connected probe is performing optimally, providing assurance with every test result.

Extended Battery Life with Alert

Power your testing sessions with long-lasting batteries, offering up to 1400 hours of continuous use. A blinking icon warns you when the battery drops below 10%, and the meter will automatically power down to prevent inaccurate readings due to low power.

Adjustable Auto Shut-Off

Conserve battery and enhance safety with the automatic power-off feature. Choose to shut down the meter after 8 or 60 minutes of inactivity, or disable it for continuous operation, providing flexibility and energy efficiency.

Engineered for demanding environments, the HI991001 boasts a robust, waterproof construction and a user-friendly quick-connect probe system.

Reliable Waterproof Design

With an IP67 rating, this meter is built to endure the challenges of daily use, resisting dust and water ingress from any direction. Its durable housing ensures consistent performance even in harsh conditions.

Comfortable and Portable Operation

Designed for easy handheld use, the meter features a clear, multi-level LCD that provides simultaneous pH and temperature readings from wide viewing angles. Simple two-button operation makes testing straightforward for all users.

Seamless Probe Connection

The Quick Connect DIN connector allows for swift and secure attachment and removal of the pH probe. A protective rubber sleeve on the connector ensures a watertight seal without the need for twisting, enhancing the probe's longevity and measurement reliability.

Ensure precise pH analysis in manufacturing and environmental applications with the HI991001's specialized HI12963 electrode, engineered for robustness and accurate measurements.

Purpose-Built for Manufacturing & Environment

The HI991001 features the HI12963 replaceable probe, specifically designed for the pH conditions encountered in diverse manufacturing processes and environmental testing protocols.

Durable Titanium Body

The titanium body of the electrode provides exceptional protection against accidental damage, making it ideal for use in challenging environments like plating baths. It also acts as a matching pin to minimize interference from electrical noise.

Integrated Temperature Compensation

The built-in temperature sensor ensures rapid and accurate temperature-compensated pH readings, even when sample temperatures fluctuate quickly.

Renewable Cloth Junction

If readings become slow or erratic, simply pull a small portion of the cloth junction outward to expose a fresh, uncontaminated surface, restoring optimal performance.

Everything you need for reliable pH and temperature testing is included with the HI991001, right out of the box.

General Purpose Electrode Cleaner

The included cleaning solution is specially formulated to remove common contaminants, keeping your electrode clean and ensuring accurate, consistent measurements. This concentrated formula helps maintain your probe in optimal condition.

Convenient pH Buffer Sachets

For precise pH calibration, we provide starter sachets of pH 4.01 and pH 7.01 buffer solutions. These single-use sachets are individually sealed to guarantee freshness and prevent any contamination, ensuring a reliable calibration process every time.
