Professional Waterproof Portable pH/ORP Meter Hanna Instruments HI98190

Description

Bring the performance of a benchtop pH meter with you when you use the HI98190 handheld pH meter. This professional, waterproof meter accurately measures pH, ORP and temperature. Built-in diagnostic features for the most precise measurements and logging so you never miss a measurement, the HI98190 is the perfect tool for environmental and industrial testing.

• CAL Check™ electrode diagnostics system alerts you to potential calibration problems so that you know your results are trustworthy every time.
• Everything you need for field testing in one compact, durable carrying case.
• Great for environmental and industrial testing.

For the measurement of pH, the HI98190 handheld pH meter comes with an HI12963 titanium body amplified pH electrode with a built-in temperature sensor for automatic temperature compensated readings. The titanium probe body is chemically resistant to aggressive chemicals and is virtually unbreakable. The HI12963 pH/temperature electrode features a newly designed Quick Connect DIN connector that provides a simple waterproof connection without any threads.

Hanna’s unique CAL Check™ feature alerts the user to potential problems during the calibration process. By comparing previous calibration data to the current calibration, the meter will alert the user with display prompts when the probe needs to be cleaned or is broken, and if the pH buffer might be contaminated. After calibration, the overall probe condition is displayed as a percentage from 0 to 100% in increments of 10%. The probe condition is affected by both the offset and slope characteristics of the pH electrode and is displayed on the measurement screen on the day of calibration and in the GLP data. Calibration can be performed up to five points with seven preprogrammed standard pH buffers and five custom ones to achieve a pH accuracy of ±0.002 with ±0.001 pH resolution.

Pressing the “AutoHold” virtual key seen in measurement mode, the portable ph meter will freeze a stable reading, allowing for the reading to be documented or logged. An “out of calibration range” warning can be enabled that will alert the user when a reading is not within the bracket of calibrated pH values.

The log-on-demand mode allows the user to record and save up to 200 samples (100 for pH and 100 for mV). This data, along with the associated GLP data, can then be transferred to a PC with Hanna’s HI920015 micro USB cable and HI92000 software.

The high contrast graphic LCD is easy to read outdoors in bright sunlight as well as in low-lit areas with the use of the backlight. A combination of dedicated and virtual keys allows easy, intuitive operation in a choice of languages.

The compact, durable carrying case is thermoformed to hold all necessary components for taking a field measurement, including the meter and electrode, beakers, buffer solutions, cleaning solutions, and storage solutions.
