Description
The HI991001 meter is built for professionals who need accuracy, durability, and ease of use in the field. Its wide LCD simultaneously displays pH and temperature readings, along with calibration instructions and battery status. With a pH range of -2.00 to 16.00 and 0.01 pH resolution, this meter delivers high precision (± 0.02 pH) comparable to larger laboratory instruments. Automatic buffer recognition and calibration stability indicators guide users through measurements, while the rugged IP67 waterproof casing protects internal electronics and ensures years of reliable use.
The included HI12963 pH electrode features a titanium body resistant to harsh chemicals and an internal amplifier to reduce electrical noise. Its extractable cloth junction allows easy maintenance by clearing blockages, extending electrode life. Built-in temperature compensation ensures readings are accurate across a wide temperature range (-5 to 105°C). The meter also includes HOLD functionality, BEPS battery protection, low battery alerts, and auto-off to maximize efficiency and reliability, making it ideal for environmental monitoring, water treatment, and chemical processing applications.
